Airline reviews

There was a lady pilot. She helped an older lady get on and off the plane and she helped me with my crabby children get off the plane. It meant the world to me. One of the flight attendants was berating a family in front of me about the 2 year old child’s inability/willingness to wear a mask. I am all for wearing masks, but a little child who doesn’t understand why it’s important to wear a mask and is melting down - is it really that important. I understand the need to follow policy’s.

Read more about Delta

We flew First Class to LA from Denver on the Delta-branded contract airline - Sky West. On the way back, we flew First Class on a Delta Airlines owned jet, and the experience was so much better. The flights should have been comparable; but unfortunately cost-cutting by Sky West was evident.

Pros: "The staff at Delta are always friendly and helpful and they were able to squeeze me onto a very full flight."

Cons: "The main economy seats were far too narrow."

Pros: "I always have a consistently good experience on Delta. Everything was great."

Cons: "It was a Great flight. I always enjoy flying Delta"

Cons: "Not really an experienced flyer. Overall the flight seemed good. No issues with airline or airport. Just don’t understand self-important people that feel compelled to push the overhead storage limits with their bags."

Cons: "It was hot"

Cons: "Flight was delayed and completely packed so our family could not get seats together"

Pros: "Love the fact that the head rests move to support your head better."

Pros: "The male crew member was excellent. He was responsive and speedy with trying to find a solution. He gave me a few flyer miles for my trouble and was empathetic, which is rare."

Cons: "The tv/monitor didn’t work so there wasn’t any entertainment for the majority of the flight."

Cons: "No meal option and my video screen volume did not work"

Pros: "Boarding was easy."

Cons: "I am 6' 1" tall and weigh 220, so not out of the ordinary and I felt like I was stuffed into a sardine can."

Pros: "Entertainment"

Cons: "Boarding at JFK.Always messy"

Pros: "Boarding was quick"

Cons: "No entertainment, plane was small"

Pros: "Good entertainment selection and great crew"

Cons: "Seats are more uncomfortable relative to other airlines"

Cons: "First delay notification: 1 hour 20 minutes 1 hour later, Second delay notification: 3 hours 15 minutes 2 hours later: Third delay notification: 3 hour 50 minutes Fourth delay notification: 4 hours 25 minutes Fifth delay notification: 4 hour 32 minutes No explanation for reason. Last time flying Delta."

Pros: "Early and middle seat was open!"

Cons: "Coffee tasted like fish. :("

Pros: "Entertainment choices were excellent, many new movies available, so I was able to see movies is been meaning to watch. There were drinks available."

Cons: "The air vents barely trickle out any air anymore. No relief to be had. Airline crews say hi and goodbye but that doesn't make them friendly."

Pros: "The crew on the airplane was great. We had 2.5 hours turbulences but the crew started to give out drinks as soon they got the ok from the pilot"

Cons: "We went in LGA to the Baggage drop off and the employee there was super rude. On the flight to New York with Delta we had to check our carry ons at the gate because it wasn't enough room for bags in the airplane.so we asked when we checked our one suitcase if we can/should check our carry ons to avoid having to do it at the gate. The delta employee told me sure no problem. He checks in my one suitcase I purchased gives me the tracking paper and says ok have a good flight. I asked him so what is with our carry ons and he told us that that would cost 25$ and we can't check those in at the drop off?!?We ended up taking the carry ons with to the gate and then off course there wasn't enough room on the airplane that we had to check it in. And surprise it was free?? We had never issues with Lufthansa, icelandair etc. with checking our bags at drop off to not needing to carry it around and than still end up to check it at the airplane. Every airline has been more than happy that we volunteer to check our bags that they don't have the trouble at the gate."

Pros: "We boarded close to on time, no hassles. Allowed my husband and me (retired military) to board early, thank you."

Cons: "LAX security is awful. We never left the airport (arrived LAX from Sydney AU) yet were forced thru security again. Had to remove shoes, was scanned and "frisked" by TSA to get to Denver. To go to Australia, Denver TSA waived the removal of shoes, skipped the scan for the metal detector and no one touched me, ditto for LAX on the trip to Sydney. Where's the uniformity or standards for TSA?? Why did I have to be subjected to this garbage on the way home?? This is why I despise flying. It makes no sense to me. This ruined what was a great vacation."

Cons: "Very little leg room."

Pros: "JFK to Denver the flight Attendants were once again great. Lots of entertainment choices again. The usual rough air coming into DIA."

Cons: "From JFK to Denver the seats were to close for leg room by an inch or two. The temperature was hot most of the flight."

Pros: "Love the built in tv’s with free entertainment."

Cons: "The plane got delayed on the runway and the shut the engines off so the plane got super hot, but even after we got up in the air it never cooled down. Normally I’m freezing on flights, but I just sat sweating this whole flight. It was terrible."

Pros: "I usually have had great experiences with Delta. The meal selection was limited. By the time they made it up to my seat they had run out of what we wanted. Also, the entertainment system at my seat and my husbands wasn’t working well. One of the bathrooms had a cabinets Tvst oliiiooooiiooooioiooiiiooiio"

Pros: "The staff really helped me out getting on standby so that I didn't have to wait for a 9 hour layover. Overall great experience and great staff."

Pros: "Everything was perfect !! Staff friendly"

Pros: "Excellent piloting and cabin crew."

Pros: "It got me home, eventually."

Cons: "Poor communication, a 6 hour delay followed by a 7 hour layover (during which we had to sleep on an airport floor because Delta couldn't offer us any hotel vouchers). Gate agents disappeared after 7pm becuase they were due to be done with their shifts when our flight was originally supposed to leave at 6 pm. It felt like we were trapped in the movie The Terminal. Oh! And our bag was misrouted, because that was just how things went those 2 days. All in all a 6 hour trip turned into 18 hours. I could have driven home in that amount of time!"

Cons: "Check in lines were crazy long"

Cons: "My daughter was stuck in SLC for 5 hours because there 1 cancelled flight and 1 delayed flight. It was very upsetting not knowing when she going to arrive in Denver."

Pros: "First leg from San Diego was excellent."

Cons: "Arriving in SLC discovered out flight to Denver was CANCELLED! Had to reschedule to the next day. Not fun!"

Pros: "App is good and convenient to use."

Cons: "The app went down just as we were getting ready to board and luckily i had a printed pass and it took some extra time to check in."

Pros: "really helpful and friendly service and nice seats."

Cons: "We left late, it was delayed then maintenance issues. Twice. Seating was very tight and uncomfortable, no movies or entertainment at all. U.S. flights are the worst. Even on short flights with aeromexico outside the U.S. you get movies and food. Zero stars for comfort, food and entertainment."

Pros: "free texting and entertainment!"

Cons: "our flight was delayed half an hour."

Cons: "I don't like that I already completed this survey several days ago and have been receiving reminders to do so. I guess you don't have a good system in place for knowing who has and has not completed your surveys. That's too bad."

Pros: "The boarding process in Atlanta was as smooth as could be expected given that it was a full flight. I appreciated the gate announcer's suggestions to everyone about how to ease the overhead baggage crunch."

Cons: "Economy is very tight quarters."

Pros: "The plane, crew was clean, newer and had TV's in the backrests. Remember to bring headphones! Seats are tight, but the crew was friendly and may the flight experience positive."

Pros: "Friendliness of staff. Second flight was a newer plane - sweet!"

Cons: "For a long flight perhaps a little more in the snack department."

Pros: "Crew was all very nice"

Cons: "Flying is always uncomfortable"

Cons: "Excellent service excellent pilot"

Pros: "Flights were both on time and boarded quickly. Crew was wonderful!"

Pros: "Free in flight entertainment"

Cons: "One of my bags went to Santa Fe"

Pros: "Entertainment"

Cons: "This is my third flight this year with Delta and every time we wait for the "crew" to get off from another flight. And as soon as they get there we can board. It's getting very annoying. Fix it."

Cons: "I'm tired of Delta making it IMPOSSIBLE to experience benefits of my loyalty. I flew literally AROUND the world in the past 6 months and it STILL doesn't qualify me for anything more than Silver elite? Seriously? When you use a voucher because of their error to lower your ticket price, but still pay cash for it, why does that then automatically exclude you from upgrades? Poor customer loyalty, in fact, non-existent these days."

Pros: "Early arrival. And service"

Cons: "I was assigned very last seat and there is no reclining option."

Pros: "WiFi, good flight attendants"

Cons: "Would like to see Direct TV along with Delta Suite so can watch live TV"

Pros: "Attendants and entertainment"

Cons: "Delays for no explained reason"

Pros: "plane had individual movies for free with each seat!"

Everything went smoothly except the 15 minute wait for ground crew to move the jet bridge to let us off the plane.

Cons: "Too much to write down. Start at the counter and work yourself to the plane. I hope you get it right eventually, I’ll be flying Southwest"

Cons: "Feed me"

Cons: "Less crowded."

Pros: "Crew was great. Love that the soft drinks are still free, unlike some other carriers. More leg room in the plane as well"

Cons: "Delay of 1.5 hours for “fuel” reasons that were sketchy at best. Luckily we were not one of the many that missed connections"

Pros: "Flight was on time"

Cons: "Carry-on luggage needs to be monitored more closely. I saw one passenger with three pieces. Meanwhile, I had to stow my bag 10 rows behind me."

Pros: "Friend service"

Cons: "Food, seat comfort."

Pros: "I feel like there is more leg room in the seats then in other discount airlines! I like the snack and drink, this breaks up the flight a bit. This is nice for me because I don’t like to fly."

Cons: "The staff seemed miserable. No one was nice or even smiled. Just felt like they couldn’t wait for this leg of their day/trip to be over."

Cons: "Ticket agent was rude and 3 flights later found a super sweet ticket agent but 10 hours longer to get to my destination"

Cons: "We stay stuck in PVR"

Pros: "Seating was comfy with techy was to entertain yourself."

Cons: "Boarding was delayed due to the plane not being ready. Baggage handling absolutely destroyed my wife’s new luggage. Her suitcase came with a cover to help keep it clean. The cover was ripped in several locations and the whole side of her suitcase was blown out. We will have to purchase new luggage."

Cons: "This plane needs to be retired! It was the most uncomfortable seat I’ve ever had! Also the plane was extremely warm. Like a sweat box or a sauna. Miserable flight. Glad it wasn’t long!"

Cons: "Usual uncomfortable seating. Plane was not pulled into a gate. DCA should be an embarrassing operation for American."

Cons: "Very good"

Pros: "It got us there"

Cons: "Beverage service was cancelled due to turbulence but I’ve been in flights worse and they kept their service Had to wait long for a ramp at a remote terminal then take 2 shuttles to terminal."

Pros: "Lots of legroom with good complimentary foods and drinks."

Cons: "Overhead speakers in he plane weren’t very loud."

Cons: "Very confused as to why I am receiving messages regarding confirming flight and post flight review when I did not purchase this flight. I watched it, did NOT book it. I should not be charged for it."

Cons: "To many delays."

Pros: "Great service and sweet attendants"

Cons: "Person next to me was a little large and it was uncomfortable."

Cons: "Delayed for mechanical."

Pros: "I loved the attitude and helpful approach of the female flight attendant working the AA gate for the flight I took from DFW to COS last night (6/13). Truthfully, it was almost like I was back with Southwest. She was kind, calm, polite, efficient, and capable. Very rare in my experience with American Airlines yesterday. Interacting with her was refreshing."

Cons: "Getting home to Colorado Springs at 11:30 PM, taxiing for 15-20 minutes, and then waiting another 20-30 for checked luggage! Never have I waited that long during and after a Southwest flight! AA could truly learn something from their more modest counterpart. I have all but decided to resume my drives to Denver every other week rather than risk more and more time and poor experiences with AA flying in-and-out of Colorado Springs."

Pros: "Flight attendant actually seemed to enjoy job even had genuine smile. Made that the most enjoyable flight I’ve had in awhile"

Pros: "Time of flight and on time flight"

Cons: "Lack of gluten free snack Cramped knee room"

Cons: "Horribly made me cancel flight because of 1min after 30 min cut off for boarding pass. Sat at the front desk for 29 minute arguing until my plane left."

Pros: "Everyone was nice"

Cons: "No gluten free snacks. Flight was late"

Cons: "Racist gate agent made me check my baggage even though it fit."

Cons: "Three hours delay. I paid for a upgrade to first class. But because of the flight change i didn't get to keep my upgrade and I had to beg for a refund. I have had two trips in the past 5 days and all flights have been anywhere from 1 to 3 hours late. Worst experience with AA I have had in a long time."

Pros: "Great service"

Pros: "Love the entertainment system, watched a movie and was able to charge my phone too"

Cons: "Gate the boarding process but that's about it"

Pros: "Absolutely none of it"

Cons: "The entire experience was the worst flying experience of my life"

Cons: "there was screens but no movies or anything"

Pros: "Flight was super cheap to France. Excellent value"

Cons: "I could not use the automated kiosks with my ticket"

Pros: "Very nice in flight staff"

Cons: "Flight delayed and the costumer service was very bad in terms of providing information to the costumers, I have called and there was no proper line to reach them at, I got my information from British Airways, as they were operating the flight."

Pros: "I liked that the internet connection was free because I am a T-Mobile customer."

Cons: "Boarding the plane was a bit clumsy. I felt like everyone was tripping over each other since the front of the plane was boarding first."

Pros: "We didn't crash."

Cons: "No safety briefing for infants, rude gate staff, primitive fleet, terrible customer service at all levels."

Pros: "Courteous and professional crew"

Cons: "Delay taking off, due to technical issues with aircraft. Seat area is much too small for an adult."

Pros: "On board flight entertainment did not work No kid friendly meal options Bags checked onto the wrong flight from PHL-DEN"

Pros: "All flights were on time. American Airlines personal is extremely friendly"

Pros: "Priority boarding provided by my credit card"

Pros: "I did not like any of it."

Cons: "We couldn't hear any of the group calling. There were so many different reward members that by the time group B was called I had to check in my baggage. I was not able to pick another seat during ticketing. When I fly for business I generally have a carry on so I can quickly catch my ride however dour to check in of my baggage I had to wait another 30 min before I received my baggage. Air hostess were not very friendly or helpful."

Cons: "The flight was incredibly delayed."

Pros: "Kind and attentive crew"

Cons: "Was a bit delayed"

Pros: "The crew was very nice and warm"

Cons: "The entertainment was poor and not visible from everywhere (understandable from an old plane)"

Cons: "the flight was 4 hours late. we were constantly shuffled to different gates. the internet on the flight didn't work."

Cons: "American canceled my original itinerary on direct flight to Los Angeles and put me on a flight to Dallas, Dallas to LA, and charged me for the change. After 8 hour delay at airport (boarding plane, on the runway) they turned us around and flight was delayed to the next day. I luckily got a direct on United and will avoid American at all costs."

Pros: "The flight was on time, and the crew was friendly."

Cons: "The boarding was very disorganized and took a long time, and there was no silverware on board, which I needed."

Pros: "N/A"

Cons: "It took so long for me to leave this airport. I got there around 11:30pm and my flight wasn't till around 9:45am the next day and so when it came to that time they had cancelled my flight so I got another ticked for around 2pm and they didn't board that flight till around 4:30. My experience there was to much to handle. I was supposed to get to Colorado Friday night but didn't even get here time Saturday afternoon. Really upsetted me because I leave wednsday so I don't have enough time to be with my boyfriend. I honestly don't think I'll be flying American Airlines again"

Pros: "Good entertainment choices, boarding in both the front and rear of the plane was great - it's common sense to board both when available or to at least board the rear of the plane first."

Cons: "No food"

Pros: "The flight attendants were nice and the plane was on time."

Cons: "I tried to switch my flight to an earlier time. First, they charge $75 (Southwest is always free). Second, the gate agent charged me and let me board, but her boss came on the plane and pulled me off because I wasn't Executive Platinum status! The plane took off with an empty seat and I had to wait two more hours for the first flight. When I complained to AA about it, they sent me a $50 voucher. I don't plan on giving any business to AA for the rest of my life."

No frills airline. Aircraft are clean and staff friendly.

Not a flashy airline but they got the job Done.

Cons: "Flight delayed due to plane problems."

Pros: "Comfortable leg room"

Cons: "Delayed as usual"

Cons: "The landing. the approach was so rough. I've flown 6 times this year. And that was the roughest approach ever"

Pros: "Not much after sitting in the airport for two extra hours on both flights"

Cons: "They could have boarded flights on time or at least explained why the flight had been delayed."

Pros: "Direct flight was very nice. Took off on time and arrived slightly early. Flight crew was friendly and efficient."

Cons: "Baggage check not staffed until 2 hrs before flight and then it's a 20-30 minute wait to check a bag. Seats were uncomfortable, but tolerable for 2 hrs."

Pros: "Nothing"

Cons: "Flight attendants talked loudly the whole flight. Very uncomfortable"

Cons: "Amazing flioght and service."

Cons: "Unclear pricing for carry on bag, could have saved $30 by paying at the ticket counter (even though I was sent an eticket and boarding pass); got stuck paying $50 at the gate."

Pros: "No leg room & very misbehaved children sitting behind me. The children screamed the whole time, kicked our seats, and the mother had no control. If you are any taller than 5’9”, you may want to consider an exit row seat to have room for your legs. My knees were jammed in to the seat in front of me."

Pros: "The crew was good , plane was delayed and late for departure. Second flight was delayed by 2 1/2 hours , I just can’t catch a break !!"

Cons: "I could not log onto the website and check my carryon bag , cost me $50 at check in. It would not recognize my number for the first flight. I’m a known traveler on Frontier so I did log in with them ."

Pros: "On time flight... good stew's, all around pleasant experience."

Cons: "the seats are hard and very narrow."

Pros: "Definitely the price. Fairly quick boarding process, just a little congested. Decent priced drinks."

Pros: "Crew was good, quite friendly and helpful. Seats are a bit uncomfortable but what airline isn't."

Pros: "Nothing"

Cons: "Still in Reno. Aircraft broke down"

Pros: "Timely"

Cons: "Signs at the airport and terminal info"

Pros: "The staff was friendly"

Cons: "The flight was delayed multiple times, the directions on having boarding passes on the app or printed prior were not given so found that our last minute to avoid paying the front desk clerk $5.00. The flight landed 5 hours later than scheduled which is completely unacceptable."

Pros: "Timing and ease of travel"

Cons: "Nothing"

Pros: "The plane was very clean and well lit. The crew was excellent. Very friendly and nice."

Cons: "The seats are pretty uncomfortable. They are so close together and there is no room to store anything. The tray tables are a joke, you can't even fit an iPad on them. The bag check process was trouble at both legs. They have lower weight limits than the major carriers and that really should be highlighted better when you book with Allegiant. Also, bag checkin for the flight I was on started at 7:45am. There were only 2 people at the checkin counter and one of them was busy doing something and ignoring the customers. So that was a little annoying."

Pros: "On time"

Cons: "initially assigned to center seat."

Cons: "Flight was delayed 6 hours."

Pros: "Non-stop flight at a reasonable price"

Cons: "Food choices are very limited"

Cons: "Seats are hard"

Pros: "Quick and easy boarding, on schedule and the cleanliness of the cabin."

Cons: "Extra charge to make use of the overhead bins. This does not include extra work or cost for Allegiant. Lack of legroom; take out two rows of seating and make the current size of travellers comfortable."

Pros: "Great price, flight on time , great trip would use again"

Cons: "I am so angry booking with them. I booked the flight and then thought, ok I will add a rental car. It said clearly that the rental Car could be canceled up until 24 hours before the flight. Well, 2 weeks before the flight, my friend said, don’t get a rental car, I will have my car. So I cancelled and only then did I find out that once I booked it through their site I could not get a refund for the car and I could only get a voucher for use on one of their flights! And only after they take out any fees and costs that was accrued! So angry!"

Pros: "The entire crew we're so accommodating and Robin was hilarious, made the hassle of traveling enjoyable and entertaining."

Cons: "Nothing all was great!"

Pros: "Everything the service for breakfast , the interpretation for more information about when you’re in a plane what to do in case something happened and stuff"

Cons: "They didn’t have a WiFi on for the plan I couldn’t use my phone at all"

Pros: "Friendly staff"

Cons: "Last minute delay due to a plane malfunction. Was told very last minute. Seemed like there were no quick resolutions in play. Had to wait over three hours to fly out, doesnt that entail compensation by law?"

Pros: "Priority check-in and boarding were pleasant."

Cons: "Very tight seats, even for a small person. No recline. Screaming children throughout the cabin."

Pros: "We got the brand new AB 320 on both flights! Nice plane!"

Cons: "Lightning delayed boarding and departure for hours. Not Allegiant's fault but it happened."

Pros: "The original booking price was great."

Cons: "All of the additional charges for the flight may make other airlines cheaper. You even have to pay extra if you pick a seat before you check in at the airport. If you don't print your ticket online or save it to your phone, you have to pay extra for that too! Overall, the worst part about the flight was that the seats are actually very uncomfortable. I'm not sure if this flight was now worth the original case posted."

Pros: "Great service and very clean plane. Staff did everything to accommodate everyone's needs."

Cons: "There was a lot more turnulance than expected which could have made for our shaky landing but the pilot did a great job regardless."

Pros: "Best flight for its Price. It was on time."

Pros: "Cheap"

Cons: "Literally had to pay for every little thing that is usually included in other airline tickets."

Cons: "Even snacks and water are only available for a fee. Seats do not have much padding and are not comfortable."

Pros: "Cost. I felt like I got what I paid for. With big name carriers I'm never quite sure what I'm paying for. Allegiant got me from point A to point B in the same manner. I just didn't get complimentary peanuts. And I'm quite okay with that. Seating, space, cleanliness was the same as other carriers. As long as Allegiant maintains their planes I'll keep flying with them."

Cons: "Everything was satisfactory. I don't have any complaints about this flight."

Pros: "Setas were good. Good price and good boarding system"

Cons: "Aircraft cabin was a bit dirty"

Pros: "Yes"

Pros: "Crew on both our flights were very nice and accommodating."

Pros: "United delays"

Pros: "Nothing"

Cons: "Arriving on time to make my connection!!!!!!"

Pros: "Plane wasn’t full, crew was great"

Cons: "They could have better food options for a 7 hours flight."

Pros: "Nice crew, good take off and landing"

Cons: "We were an hr late taking off."

Pros: "Good leg room"

Cons: "Seats are narrow. Not much shoulder space"

Cons: "Wouldnt refund my ticket or change my flight when I needed to change it fee for everything"

Pros: "Flight was ok"

Cons: "Flight delayed 3 1/2 hours because there was no hydraulic fluid available and had to be driven up from Phoenix."

Pros: "Nothing, worst experience I’ve ever had traveling. Up for nearly 2 days and with no help from the local airport staff."

Cons: "Everything, no customer service whatsoever"

Pros: "Everybody was wonderful. All the staff were friendly and the flight was great."

Cons: "I volunteered to gate check my instruments (which I NEVER do because it’s not my hobby, it’s my livelihood). When I did, I made very clear that I’ll ONLY do it if it’s handed to me at the gate when I arrive. It CANNOT go into baggage claim because it’s 2 $3000, left handed, vintage Paul McCartney basses packed in one bag. The gentleman assured me that I’d have it handed to me upon arrival. It isn’t designed to go through the rough handling of people I’ve never met or trusted. So I got to Denver and waited at the gate until someone told me, “oh no that’s gonna be down in baggage claim” Needless to say, I’m scared to death and I don’t even know where $6000 worth of instruments of mine, is right now. I wish people would communicate when they promise things."

Pros: "Seats were comfortable, we were in first class. United provided a good selection of recent movies."

Cons: "United stewardesses have little to no interest in their duties. Questions were clearly an annoyance to them. The leg of flight from Denver to Des Moines was very uncomfortable, seats much to tigh, no leg room. Gate staff in Denver were exceptional. United needs to revisit their time for loading. We preloaded, I had a broken leg, I was traveling with a special needs woman. We just reached our seats when other passengers were prodding us to sit so they could board no time to settle. Not impressed"

Cons: "Lost bags and every time I called to find out where they were I would get a different story. I was told it would be on the next flight for the next 5 flights."

Pros: "The flight attendants were so nice, and although our flight was delayed and hour and fifteen minutes and our layover was an hour and fifteen minutes, we were able to make our connection! Since our connection to Portland in Denver was the last flight of the night, they were able to hold it for us. This was wonderful because there weren’t many flights out that weren’t booked solid for the next day. The attendants on this flight were great about updating us with information for the connections and telling us when we would land in Denver."

Cons: "The plane was delayed over an hour for cleaning. It was frustrating to say the least."

Pros: "The flight was on time"

Cons: "This was a smaller plane (4 seats across). Knowing this, they didn't bring enough luggage carts, so they only brought some of the luggage to the baggage claim and didn't tell us this. 5-6 of us waited and waited and finally asked someone who told us that they had to go back to the plane to get the rest of the luggage. Those of us still waiting got to wait another half hour for our luggage. Talk all they want, United just can't seem to get it right. PS: those of us who had to wait were the ones who got to the San Antonio airport the earliest and thus our luggage was on the plane first."

Cons: "Seats to small. But I am 6'3"" and my son traveling with me is 6'5"."

Pros: "The leg from Denver to vegas was awesome"

Cons: "The first leg didn't have any snacks and a cold continental breakfast. American and Delta's breakfast is much nicer. But worth the price for that portion of the leg."

Pros: "Nothing"

Cons: "The plane was freezing. I needed to put on socks--really wished I had packed wool ones. The seats were cramped and mine did not recline."

Pros: "free movies on the flight with the united app"

Cons: "The flight attendant was late delaying boarding 20 minutes. Once they started, people were lining up to board. This is a normal behavior however, there employee decided to stop boarding because she said people were crowding. she stop boarding for another 20 minutes. Now, this was a large flight and there wasn't enough room for everyone to stand off to the side. She was rude and there was no reason for this especially when the flight attendant was already late. The plane was delayed 45 minutes due to this"

Pros: "I was sat in an exit seat."

Cons: "The lady in the seat next to me was so overweight that I couldn't sit comfortably for the entire flight - I had to lean out and it hurt my back!"

Pros: "Nothing I won't be flying united again!"

Cons: "The lady at the gate when boarding was not friendly and was not willing to help us get seats together. I was traveling with my mother, husband and two infant children. And it was like pulling teeth to get any information out of her. She did not even tell us we could board early to get situated on plane! I also called earlier that morning and spoke with a man on he phone at united who told me he put us all in the same row. That was a lie bc when we checked in at the gate to get our seats the lady said no one was sitting next to each other! That lady was rude and short tempered! Awful experience will never fly again!!"

Cons: "The default on the browser defaulted to April 9 when I was actually booking the ticket for April 2. So I had to forfeit the $317 ticket. I use kayak a lot - can anything be down ?"

Pros: "Everything went fine and they sorted out a spot for me to sit even though the flight was overbooked"

Pros: "Food was edible, nothing special"

Cons: "Boarding was very slow, as was cabin staff. Not very attentive. Made a big deal about letting passengers with connections off first, although we arrived. We waited, as requested. Finally got up,after realizing everyone in the 20'rows behind us was gone."

Cons: "My friends dad passed away and was unable to get money back to go to his funeral. Plane was a small express plane which was never mentioned. Had to check bag because overhead bins were too small. No wifi. Dad and Kid took my assigned seat."

Cons: "Total flight was cancelled got trapped in Denver next flight was going to be out 3 days later. Customer care locations were closed. Still lost baggage. Had to rent a car in Denver and drive 2 Durango on icy roads. Totally terrible Airline and a terrible experience."

Cons: "Flight was delayed to 4 hours now I'm rushing all over to get to my connecting flights"

Pros: "Small airport, comfortable seating, polite crew"

Cons: "Snack wasn't my style"

Cons: "Unable to pre-check online. Unable to check at the check in machines--had to go up and check in at the counter, long wait because there was only one clerk. We were then given a ticket just to get through security and had to check in a second time when we get to the gate for seat assignment, which is ridiculous. Why couldn't that be done at the 1st check-in? The clerk told me she will call me when she has the seat assignment/ boarding ticket but she never did and I had to go back up to ask for them when it was getting close to boarding time. At the last moment minutes, volunteers could check in their carry on for free....It would have been nice (and less hassle) to have that option at the 1st check-in."

Pros: "Quick and easy boarding, friendly staff, On time/early to arrival"

Cons: "Not a lot of space for passengers- even someone small like me at 5'2 and 120 lbs. Flight was also a bit turbulent"

Pros: "Nothing"

Cons: "I'm usually a patient person, but my flight was supposed to leave at 525am and didn't leave until 730. This was the first flight in the morning. We boarded, waiting 30 minutes on the plane, they told us to get off because there were computer issues. Why wasn't that checked before everybody was boarded? Once we got on the plane we had to wait another 30 minutes for the crew to get someone's luggage from under the plane. Why wasn't that done while the computer was getting fixed? I didn't get to Denver until 1040am missed my flight and didn't get to get on my connection until 500pm. In the meantime I called to get on a different flight at 1, but the guy on the phone didn't actually book me a seat. The gate people weren't very nice."

Pros: "We were on time. Crew members were good"

Cons: "Snacks were too little!!"

Cons: "The flight attendants were disrespectful to not only me but to other passengers. They were not attentive! The plane was dirty."

Pros: "Boarding was very fast and efficient. Seats were as expected on an airplane. The flight was only 45 minutes so there was no entertainment or food to really be able to rate them on it."

Cons: "The one flight attendant spoke super fast so it was a little hard to hear her clearly."

Cons: "A la ahora de irnos hubo muchos contratiempo por el tiempo pero por el vuelo después que nos fuimos fue excelente"

Pros: "Very friendly and helpful staff."

Cons: "The fact that we had a connecting flight to minot from Denver. Arrived late to Denver because of weather, but my stroller that I had left on the jetway in Seattle was never put on the plane which I didn't know until I got to minot. I was going to wait for it in denver, but I would have missed my flight to minot had I waited 5 more minutes. We arrived to minot only to find out that our 3 suitcases, one stroller and 2 car seats were never in the flight. Awful! And my connecting flight was even delayed an extra 55 min so I don't quite know where my things are."

Pros: "Crew were fine."

Cons: "Seats are narrower and make for a lot of discomfort when stuck in the middle seat. I do not like other stranger's bodies touching mine. That is just wrong."

Pros: "The staff was very helpful"

Cons: "Turbulence was horrid. Had to re route the landing causing me to miss my connecting flight. united had no other options for 23 hours. Therefore I chose to return to my starting destination. I still had to spend the night at the airport, and missed a 10 hour day of work due to no other flight options. All I received was a verbal apology. Glad I paid for a flight to a one night stay at Denver airport and back."

Cons: "One strange thing happened on my United airlines flight. The crew announced before we boarded that there wasn't enough overhead space for rolling bags and encouraged us to check them in. Upon boarding they announced that all overhead space in the back was full. I sat in the back and noticed that the crew closed the overhead compartments even though they were mostly empty. Another passenger opened an empty one and the crew came over and closed it right away, though many people were still boarding. What's going on?"

Cons: "The airplane was freezing, and I'm 23 years old and very used to flying."

Cons: "Additional fees for extra space were 1/3 the cost of my flight"

Cons: "My flight was scheduled to leave at 4:51 pm. I arrived at the airport 2 and a half hours before my flight was to leave and I read the departure board to see that the flight was delayed due to maintenance. Then I saw that it was delayed again because we were waiting for a flight coming in from the Bahamas. Well my flight didn't take off until about 7:30 pm. I arrived in Denver around 10:00 pm which made me miss my shuttle to the Springs. I am a diabetic and was in need of my medication so I needed to get home. I spent extra money to take a bus to downtown Denver and a grayhound bus to the springs and a cab to my home. So my trip cost my an extra $55.00 dollars I didn't have. I have always taken United but after this experience, I will never again take United."

Pros: "The crew is AMAZING!!! Personal, professionals, they go above and beyond my personal standard of customer service. Very comfortable atmosphere. Not to be mistaken with the uncomfortable seats. I like to think United doesn't overlook the work ethic their employees represent the company with on a day to day basis."

Cons: "I travel for work from Grand Junction, Colorado to Dickinson, North Dakota every 4 to 6 weeks. I always fly United. On one occasion I met family in Colorado Springs, so I bought a round trip ticket from Dickinson to Colorado Springs. I missed the second half of my round trip flight from Colorado Springs to Dickinson. I had to pay my own cab fare from Colorado Springs to Denver to catch my flight, because your plane, that i paid for a flight on, had mechanical issues and didn't make it to Colorado Springs. Second, my flight in Denver was cancelled 3 times and almost a fourth. I all but got down on my knees and begged to catch the fourth flight they tried to cancel. Third, I didn't even get to fly into Dickinson. So instead of somebody coming and picking me up in Dickinson which is a 30-minute drive from where I work, somebody had to drive 3 hours to Williston where you guys ended up getting me. Which cost me 3 hours of gas money to get picked up, instead of 30 min of gas money. I didn't get either of the flights back to North Dakota that I paid for. I've asked for the reasonable request that I be refunded 50% of the cost of the airfare and the $235 it cost for cab fare. When I contacted United about this I got the runaround from everybody. At this point I've pretty much accepted the loss, and the financial hit. I'll continue to fly United only because it's pretty much my only option. Just make sure you keep the crew around. They're great. I'd hate for the experience to go from unsatisfying, to miserable."

Pros: "they gave us the whole can to drink on the flight for drinks"

Cons: "the stupid old white man at baggage check in in New YOrk who was EXTREMELY rude and made me HATE flying with UNited"

Cons: "My TSA wasn't tagged to my ticket"

Cons: "didn't make the flight"

Pros: "My flight started off with getting to the airport only to find my flight had been canceled in the morning and rescheduled at an earlier time while I was at work. I don't check my phone or email while at work. Fortunately, your staff was quickly able to put me on a flight that left an hour and a half after my original flight, but would put me on a connecting flight with American Airlines in Chicago. The AA flight had engine trouble so it turned around and we borded another plane after we landed. The original flight would have had me to my destination by 9:30 pm. Instead I arrived at 1:08 am the next day. I am frustrated that my flight was canceled so close to my departure. It was a great inconvenience to those picking me up at the airport. It added to my stress. It made it much less likely that I will fly United again. Maybe you had good reason to cancel my flight at such short notice, but it severely tainted my experience and opinion of United and American Airlines which had been fairly positive until now."

Cons: "The inconsideration for my schedule. The last minute change."

Pros: "Punctual flight, lack of major issues. Friendly staff helps on a long flight. Handled minor issues in the cabin well."

Cons: "Boarding the 747 was a bit disorganized, using doors on both sides of the gate desk led to confusion."

Pros: "Not only do I get the best price. The fact that you told me what carousel to get my bag from was new to me. I alway check kyak first but now I love u guys. I know my travel site and its kayak"

Cons: "My flight was many hours delayed due to bad weather in Denver. Then my flight from Denver to LAX was eventually cancelled so I took a direct flight from Phl to LAX on American. That flight was fine."

Cons: "No masks requirement and beverage/snack cart"

Pros: "The price and availability of the flight was good."

Cons: "The planes are cramped the seats are stiff and a bit uncomfortable, but that’s not why you fly."

Pros: "One enthusiastic elderly flight attendant was inspiring to see"

Cons: "After flight was delayed, I've never had a worse experience with an airline. My final flight leg could have waited 10 minutes and gotten me back on time. Instead there was an atrocious line at customer service, where they finally denied me a hotel room, cot, blanket, pillow...after absurdly allowing a man to cut over ten of us in line simply because he requested a translator. Multiple employees lied/gave misinformation, adding heavily to the feeling that Frontier cares little about customer service. Terrible experience!!"

Pros: "It was cheap. You get what you pay for."

Cons: "Being late. Really late. It started in the morning, 12 hours before the flight and was told it was going to be 1.5 hours late. Of course you know that is only the beginning. Then like a suspense thriller, every episode is a cliff hanger. As the moment approached for the flight to leave late, it was extended yet another hour then two. Like Tantalus, never quite reaching the object of desire, we were strung along till 10:30 for a 6:30 flight. Yet as bad as it was, it was better than coming by hand-cart. But it was a bit of a pioneering experience."

Cons: "My fiancé and I have both had awful experiences with Frontier. Both of us have had so many issues with our flights being delayed with no real explanation, apology, or compensation for our inconvenience. This most recent time I was supposed to get to my destination by 8 am and didn’t end up getting in until after 6 pm. The time before I was delayed for 12 hours before they finally decided to cancel the flight. You REALLY cannot expect anything. It’s a cheap flight and absolutely nothing more. You also get charged for every tiny little thing- including your carry on. My fiancé and I have never completely written off an entire company before but we will truly never fly Frontier again. I’d rather pay double the price to fly with a different airline than save a couple dollars and fly with Frontier. Good riddance."

Pros: "Friendly crew and desk agents"

Cons: "Fees and fees and charges and charges. No bargain in the end"

Pros: "Got to Denver on time!"

Cons: "I feel the security people went a bit overboard. I was comparing to other cities and with the scanner and shoes and taking iPads out and no food in bags.... it was overwhelming?!?"

Pros: "The crew was so warm and kind. The really made the trip."

Cons: "I fly often. Mostly internationally for work, but often enough domestically that I am a learned flyer. I hated that there was no complimentary anything on this airline. When checking in, I had to pay for my seat, after paying the stated price on this site (btwn 13-45 $). There was food and beverage, that you also had to pay for, no complimentary soda or nuts on this airline. Also there was a carry on baggage fee!!!! Like wtf. Overall, though the crew was great, I would NEVER fly this airline again."

Cons: "11 hour delay .....Flight 740 From phx to den departure @6 am had a mechanical. First it was going to be delayed until 10 am them 11 am then 4 pm then 530 pm .it left at 6 pm . It got in at 9 pm by the time we got the car and got to out friend home it would have been close to 11 . We would have been up for 20 hours ( got up at 3 am to get there for a 6 am flight . We were going to a business meeting in demver in the morning in the afternoon a 70 th birthday lunch for my best friend. This trip was planned for months . We live in phx after it was clear we had missed both events we went back home @5 We ended up paying for a supper shuttle and a rent a car in Denver . We paid all that money To go noware the customer service woman there , was uncaring to everyone on board we were just on our own . I am heartbroken we missed the party ."

Cons: "Flight delayed 2-1/2 hours, which I understood, the weather was horrible - BUT First the desk clerks were rude and as if people weren't irritated enough this didn't help Then the flight attendants were rude - all around miserable flight AND they charge for EVERYTHING - you may think you are getting a good deal on tickets, but you pay $40 for a checked bag, the same for a CARRY ON you pay for a decent seat they don't even give you peanuts without charging you I am done with Frontier - will never fly it again!"

Pros: "The crew was great. The pilot lightened the mood with humor and the announcements were useful ( weather, time zone changes, ETA etc... ). The plane was clean and the price was low."

Cons: "You have to pay forty dollars for a carry on and for any beverage or snack on the flight. There was confusion about the seats as we boarded, which we did by zones, but still had aisle traffic which defeated the purpose. My connection was moved to another gate and they failed to announce it ( yes it was on the screen, but I don't travel that often and was lucky to notice it just as we were boarding... luckily just a few minutes walk away ). The plane offers no entertainment at all ( which is fine for me, but worth knowing... bring a dvd player or something for long trips )."

Pros: "I really enjoyed the camaraderie i shared with my fellow passengers. Adversity really brings people together."

Cons: "Frontier as a whole, I was unaware, is a 'not good' airline. Smallest seats I've yet experienced, no recline, no legroom. If you don't want to pay $35 to check a bag, it's cool they understand, they'll happily take $40 to let you carry a bag on. Well, not happily. More begrudgingly than happily. Customer service was poor, bordering on hostile from one sky waitress in particular. It's hard to blame the airline's employees for their poor attitude, as I would be disheartened and upset if I was surrounded by a plane-full of customers vowing to 'never fly frontier again'"

Pros: "The trip was excellent, the flight boarded and took off on time, and we arrived early! Great flight"

Cons: "The seats are not angled to fit the figure of a person. The back of the seat leans back and the head of the seat is perfectly straight up. It meets at a point where that does not line up with the persons body height depending on the person. If you just leave it at one angle of give it the potential to lean back just enough, People will be that much more comfortable. I wasn't the only person who mentioned this on my flight, in fact I spoke with 3 people and overheard others complaints as well. One angle or at least a centimeter of space to lean back...I don't think it will mess with people behind them since there's no tv or entertainment and I think it will continue to bring more people into frontier."

Pros: "Got me where I wanted to go,"

Cons: "I am allergic to dogs and cats. This is a growing problem for me because it seems that the rules are looser and people keep a pet on their lap and service animals are increasing. There were two on board ( One not a service animal, the other one was) and I spoke to the gate agents who were mostly uninformed and unsympathetic . There is an overall lack luster with everything about FRONTIER and I get the no-frills / buy what you need concept, but there is no accommodation for people with serious allergy, and there is an increasing ability to get the certificate to have a service animal for just about any malady it seems. I respect the need for a service animal. However the passengers who have to sit in an airplane with recirculating air with dander are largely misunderstood. I asked to speak to a FRONTIER supervisor and there was no one to be seen and I got a stock answer from the gate agent in Orkando who was chewing gum so hard, it was difficult to have a conversation. Eventually I gave up my good seat to go further back from the animals who were seated up in front rows. That makes it worse when you have to pass by them to get back to your seat. And again, the gate agents were not helpful in getting me on the plane pre-boarded. Yes I take medication and sometimes I am OK and for the record, there is no truly "hypoallergic dog" for me. That is the excuse I also get. It is tough to live with when people around you do not understand . I was also recently deplaned on United airline because of this problem. I cannot stop flying it is always something now I have to worry about until I get to the gate. I do not wish it on anybody but if you had the reaction of welts itching and swelling it would be better understood as something that needed to be addressed by the airlines. Thank you for reading this long note."

Pros: "The crew were very nice and professional, the flight was on time as well."

Cons: "Yes it's a budget airline but the seats are not very comfortable and there is absolutely no leg room unless your 5'4 and they do not recline. The seating arrangement is nuts they choose for you, you can choose yourself if you join their club and you still have to pay. The carry on/checking fee is $30 if your bag is 50 lbs or less. Otherwise you will pay $75 I believe. The only thing that is free is water by the cup otherwise the small bottle water is expensive. Yes it's a budget airline so remember, on longer flights I think I would rather pay more and have a more comfortable flight. Also the Airbus 319/320 that they use suck. They are old and you feel a lot of turbulence."

Pros: "The flight arrived 10 minutes early"

Cons: "There was a lady sitting next to me with a small dog that was not in a kennel and it tried to bite not only one of the flight attendants, but me as well. The man who almost got bit told the woman that dogs should be in kennels during flights and she said "oh I don't know he's never done this before." Well awesome for you but I've never been bit by a dog on an airplane before either. The guy let it slide and moved on. The tray tables are a joke. They ONLY offer complimentary WATER. No leg room. Would not recommend."

Pros: "The staff were the only saving grace."

Cons: "There should be a place to mark horrifying. It always appears that Frontier is the least expensive until you get hit with all the little charges. We paid an extra 18$ each to choose seats, bad ones, and then the seat next to me is filled by someone who choose not to pay. Some folks paid $30 for a carry on and others just lugged uge free bags on. The flights are always delayed and the plane was filthy. I know there was no time for staff to do there short cleaning routine, this was not from a single flight,looked like floors and seat have NEVER been cleaned. UGH"

Pros: "Nothing"

Cons: "We had already paid the luggage fee and just needed to drop off our bags for our MCO to DEN flight. It started with no curbside check-in. Incredibly poor service at ticketing/baggage check. A mass of people. No directions. Even employees (when asked, not one volunteered any information) didn't know which line was which. Only four people working the counter. And then the airline called for people leaving on a flight after ours and brought those passengers to the front of the line. When we got to the front of the line the employee's response was "You need to be here three hours before the flight." For a midweek domestic flight? ATA treated us like this once. They're long gone. Goodbye Frontier."

Pros: "Not much."

Cons: "Frontier Airlines Lost My snowboard bag. No electronic system to track bags means you must rely on their human communication, and this is terrible. I can't believe they haven't invested in this type of tracking system....its 2017!!! Very bad customer service. No communication or mis communication on status of lost bag. Really they have no idea where it is. Promises to deliver lost bag at certain times and never do. Took time out of my day to stay home and wait for bag between 12pm - 6pm as they asked. Never showed up. Never called to say they wouldn't be showing up. They did this to me 3 times! It's 1 week later and I still don't have my bag. My ski trip was completely ruined. I've flown domestically, internationally, and I have never felt so uncared for as a customer. Tales of this terrible airline were told to me before I chose it. I can't stress this to any future potential customer. Choose another airline. Not worth it no matter how low the price is. Hidden baggage fees and terrible customer service will get you in the end!"

Pros: "The flight was on time and the plane was clean. The crew was very friendly."

Cons: "The airline did not provide seat assignments at booking or prior to the flight. To secure seats together with my 11 year old son, I was upcharged at the airport ($85 for tow flights). No amenities were provided. Apple juice cost $3. No in flight entertainment, not even a magazine. This flight cost as much as a major airline when I booked it--the only convenience was timing back to our original airport. Add the seat up charge and I probably paid more. This experience proved to me that it might be ok to pay a little extra for a major carrier, especially on long trips."

Pros: "They totally failed. Never again. Totally ripped me off. Almost didn't make my scheduled visit with my daughters I only see twice a year. I had to spontaneously book emergency flight with United, which was great by the way. But cause was such short notice cost me 900 dollars. Frontier did not refund my checked bag fee and left my bag in la-la land. I found it. Thank God. Then they, frontier, only refunded me 50%. Do t k of why. Will dispute. What a headache, inconvenience, rip off, and waist of valuable time. I learned. You get what you pay for people."

Pros: "Both flights were early."

Cons: "45 minute wait for baggage in DEN. No personnel available to check passengers in in PIT. We waited for 30 minutes for them to show up. Different prices for baggage depending on whether you book it when you book the ticket or if you do it at the airport. Charging for a seat reservation is nonsense. Of course so free food, not even peanuts! I am so tired of being nickeled and died by airlines that I now will actually refuse to make certain trips unless I can drive. No other industry in this country treats its customers as shabbily as the airline industry."

Pros: "The flight attendants were very helpful."

Cons: "Other than paying for the actual ticket, which was NOT cheap (approx. 40% more than getting there AND it was a "red eye" to boot) everything else was an "add on".....pay for "carry on", pay for seat assignment, pay for coffee......everything was extra. On top of this, most of the seats did not recline and had very little padding.........I guess you could pay for reclining seats. Although the Exit seats were empty, you could not sit in them unless you paid for them. My wife's reading light did NOT work.......I guess she didn't pay for the light!!! The flight attendant apologized and said it's been on a work order to fix and offered to provide another seat ONLY for her!!! I'll NEVER fly Frontier again."

Pros: "The only positive is that I actually did make it to my destination and back."

Cons: "I have never flown Frontier before, and I never will again. First off, I always travel light and never check bags. This usually means I can check in via the kiosk right away with flights, but this was NOT the case with Frontier. For some unknown reason, I had to check in with the desk agent. There was a line. A LONG line. Not only that, but there actually weren't any desk agents, as they don't show up until 2 hours prior to the flight. It took over an hour to accomplish a task which usually takes less than a minute, and due to the long line I barely made it to my flight, despite showing up at the airport 2 and half hours early. Flight #1 - Like I said, I have never flown Frontier. I didn't know it was possible to make an airplane so uncomfortable. I understand it is a budget airline, but there are ZERO comforts. The seats are grey plastic, completely rigid and with no tilt. They are crammed together so close that finding any sort of sleeping position is nearly impossible. The fact that you have to pay an extra $30 for ONE carry on and then pay for ANY sort of drink/snack equates to actually paying about the same for a flight with another airline. Want to check an item? You're actually paying MORE than you wold with another airline. Flight #2 - Took off over an hour and half LATE because the system was down. The gate agents literally read off EVERY NAME one by one, over 200 people, to check them in and get them on the plane. They also filled the plane from back to front, which is proven to be the SLOWEST way to board passengers on a plane. Flight #3 - This was an early flight. 6am. I woke up with an email alert from Frontier saying that the flight was delayed until 7:30. Understandably, I was upset. This would cause me to miss my connecting flight. Luckily, I decided to go the airport anyway instead of getting another hour of sleep. Good thing too, because the flight was in fact NOT delayed. If I had heeded the alert email, I would have missed my flight for being late. Flight #4 - This flight, on the other hand, WAS delayed. 2 hours. The gate was changed 3 times and another aircraft had to be found due to malfunctions with the first. Honestly, I don't understand how Frontier is still in business. Worst travel experience of my life. I will never fly Frontier again and I have already started telling all of my friends not to use their services. -Adam"

Pros: "Absolutely nothing."

Cons: "Where to begin in this one. To start the flight was delayed for about 10 hours. Life happens delays are inevitable but thy way frontier handled this was absolutely the worse customer service I have ever witnessed For starters after the initial delay the flight was removed from the departure board. Only a single intercom call was made regarding the delay of the flight. After this every passenger was left in the dark. Only by asking other airlines were we able to find our new exit gate and leave time. Tens out that was wrong as well and the frontier employee in staff left as soon as possible and refused to answer questions. I contacted customer support, who belittled me for missing my flight. I was told that the plane had departed at 1245 and that I should have been at the airport an hour before the departure to ensure I was on the plane. During this entire time I was staring at the plane right outside the window. There system had lost track of the plan. After being transferred to a supervisor he spent about 20 minutes trying to figure out where the plane was before he listened to me telling him t was right in front of my eyes. They lost a plane... He then attempted to explain the delay which I already knew more about than him from all of the other passengers pooling our knowledge. The supervisor (id#881311) refused to give me a guarantee or promise that e would provide a way for us to all be informed. As of this point no annocumebts ha been made, the departure board was empty, and all websites stated that we had left an hour ago. However after my phone call in about 10 minutes the website updated to show that we were now delayed until 730. Sill no information was provided in terminal. The entire flight proceeded to go to the ticketing counter in an attempt at some reimbursement for this inconvenience. There was only two frontier employees inside the entire terminal at the time. They had to be badgered for refunds. After hours we were finally given 15 dollars in food coupons... The only reimbursement for this entire debacle. No more information was provided until we boarded the plane around 830. The flight crew provided no reimbursement or sincere apologies and the entire passenger base was treated as if we were the issue. When leaving the aircraft the flight crew was unsure if which baggage claim we would be going to find our luggage so we were directed to three different claims Frontier is a disorganized uncaring and unflinching airline that is only still around by some unknown miracle. They have a 1 star review across the board on all review sites I could find and it was well deserved."

Pros: "The crew was very accommodating and pleasant."

Cons: "If I had known that Frontier charges for carry on baggage, I would have chosen another flight. I usually fly United or Air France and I shall do the same from now on. There was 0 leg room and the "tray" is only a few inches deep, which hardly fits a laptop. I was surprised they didn't charge for the use of the bathroom. I am sure that is next. I have to say the majority of people around me were expressing the same sentiments. I was also assigned the middle seat in the very last aisle. A flight attendant moved me to a better seat as soon as he could. I was very happy it was only a 2 hour flight."

Pros: "great price."

Cons: "When I arrived at the airport (pdx) I was informed immediately that I would be refunded. I knew before hand, via Google, that my flight would be delayed so I checked in at the counter to make sure I would be able to make my second flight from Denver to San Antonio, when I walked up to the counter, they asked for my name and then golf me I would need to be refunded. At this time, I tried to find out if they had another flight to San Antonio only to have the woman helping me ask "do you want me to refund the money or not? I'm about to press send." I'm sure that had the flight actually existed, I would be able to give a better review and I don't really want to mark down the crew for something, I imagine, was out of their control, but I can't give them any stars as my interaction with the staff was very limited to just the ticket counter. I will most likely NEVER fly with Frontier again based off of this experience."

Cons: "We landed in Denver and landed a little behind schedule. The flight was below average as the pilot was navigating in "bad" weather. It was not even raining. Once we landed the pilot continues to get on the radio to tell us we would be sitting for 10 minutes. After over an hour we finally moved to a gate. Now that we are over 1.5 hrs after our schedule time frontier took over another hour to get the bags to baggage claim. This is embarrassing for a company that is inflexible in changing flights, charges you to pick a seat, charges you to check a bag, and charges you to carry a bag on. They should return all their customers money from this flight I will not be flying frontier again."

Pros: "Gate agents and flight crews were very nice people."

Cons: "Seats were barely minimum quality, no entertainment systems, no food (not even a little bag of peanuts or pretzels), flights were late, and on the last leg I missed my connection, partly because we were late, but also because there was no ground crew to get the plane to the gate, so we waited over 15 minutes just meters from the dock, and watched the ground crew handle several other planes down the line, during which time my last flight must have taken off. I was rebooked on the next flight to my destination, even mentioning my checked bag, which I hoped would also be placed on the next flight out. That last flight was also delayed in departing, and when I arrived at my destination, my bag did not. I filed a claim, and was told I'd receive an email with a claim # and contact info, and my bag would be delivered to my home the following day. No emai arrived, and no bag arrived. I have filed another claim via the airline's web site, so we'll see what happens. Also, they charge high prices (IMO) for checked bags, carry-on bags (1 personal item is free), and seat selection. Not as economical as it seems at first! I doubt I will ever use this airline again."

Pros: "My husband said that there was a little more room than usual in the seats, in part bc the seats don't have a full size drop down tray. I did appreciate that the seats were comfortable even though they don't tilt back, and since they don't tilt back, it means you don't have the person in front of you tilting all the way back into your space."

Cons: "Frontier is really just another cheap airline that will charge you extra for everything now. It's annoying enough that you have to pay to get a seat assignment and to take a bag (carry on or check) but when the flight attendant said it would cost be $1.99 to get a cup of coffee, that was it for me. I also found the dinky little half trays annoying - there's no way to do anything on them. and since they don't lock, every child on the plane spent the entire trip dropping them down to hear the loud sound they made. Also with the arm rests. Oy. Also, the board of our flight out of Denver was ridiculous. The flight was delayed quite a bit and then Frontier check in person not once but twice announced we would begin boarding only to then realize it wasn't ready yet and shut the doors. It was really weird."

Pros: "Nothing"

Cons: "First leg of our trip was delayed so we could not make our connection. We were told they could fly us to Denver and catch other flight home 3 days later or completely rebook to the next closest city. (They do not partner with anyone so you are stuck with their flights) Which we then needed to book a hotel, cab fares to the megabus station, then cab fares back to our original destination. Once arriving, and even though we checked in hours before our flight, our baggage was missing along with about 10 other passengers. Frontier had no one at their baggage service when we arrived. So I had the drive 2 hours back the next day. Called the help line. The person was rude and began getting loud with me, even though they are the ones that lost our bags. 90% of all the customer service people we encountered were extremely rude and would not help. Nor were they very accommodating for all their mess ups. For all our troubles, the rude "customer service" people, and out additional hundreds of dollars; Frontier sent us a coupon for a whooping $50 to use on their airline. No thanks, will never fly this airline again."

Cons: "I've always been dedicated to Frontier but am quickly losing hope. They gave our gate away to another flight that was 3 hrs late. While boarding that flight, the gate attendant announced the Captain was on the wrong plane so passengers deplaned and started over. Our gate changed eventually. When arriving, our gate wasn't ready, and the crew had difficulty pulling in. We had a 2 hour delay with 40 minutes waiting for our baggage. Very poor communication. We found out more info on line than at gate. This was coming home. My story getting to Chicago on Frontier was as bad if not worse. Many other stories were being shared as well. Sad to see an airline that fought so hard to survive treat their loyal customers like this."

Pros: "Plane was clean. Seats were very comfortable l, but not much leg room"

Cons: "They charge for for everything on this flight. Checking in - it cost $35 to check your bag in - $40 of you want to board with it! I do all the work and I have to pay more? Then to pick a seat - any seat - it is another $5 - $25. I understand that for premium seating (ext, etc) but any seat? Finally - drinks and snacks - that costs money too. While the fare looks cheap - beware of all the add ons. At a minimum, you have an additional $70 to $100 to the price of the ticket This does not turn out to be a cheaper price....beware."

Cons: "Told at the checkin desk it's $35 per person to "confirm our seats" -- two in the exit row as all that remained. Why? I paid $250 per person to confirm I wanted on the aircraft. I showed up 1.5 hours early to check in. Also told at the desk it's $40 per checked bag ($45 per carry on!). So when I get to the airport I'm forced to pay $150 more, just to fly to my destination. Credit card only. The lady checking in next to me paid me cash so I'd help her pay her extra fees. Not how to treat your customers. That's what I call a scam. If all this was in the small print, I missed it, and it was tough to find, having booked through Kayak. Won't be duped again. Goodbye, Frontier."

Pros: "I liked that I received a text from Frontier at 430am letting me know about the first delay. Unfortunately not everyone was as lucky as me. I liked how polite the crew was. I liked how they provided me with a $100 voucher to make up for my delayed flight and allowed me to use it to pay for my carry on bag and seat on my return flight."

Cons: "The flight was scheduled to take off at 8:00 but was delayed over 8 hours until 4:30pm. It was then delayed again and ended up take off at around 530pm. Then upon landing we were told there was no gate available and we ended up sitting on the runway about 20 minutes. So I got off the plan about 10 hours after I was scheduled to get off the plane. I also didn't like that you had to pay for everything: checked bags, carry on bags, snacks, soda. I mean I thought we would at least get one free cup of soda."

Cons: "First, flight was delayed over 1 hour for non weather reasons. Next, my seat had NO arm rest cushion. It was missing. I asked the flight crew for a pillow or blanket, i was told they don't have any. They did not care about my seat not having an arm rest cushion. Next, no in flight entertainment. Once we landed, had to wait 15 minutes for an open terminal to pull up to. Then i still don't understand this, we all get up to get our overhead suitcases, and then the flight crew gets on the speaker and tells everyone to sit down because they need to get their suitcases first. Guess customers are not important to Frontier. Then lastly, not frontiers fault, but we then had to wait 1.25 hours to get our checked suitcases."

Pros: "The crew was very friendly and the plane for the most part was clean."

Cons: "This is a very stripped down way to travel. Expect to be nickeled and dimed for everything. Carry on ran me $40. However, they don't check if you actually paid the carry on fee and put your things in the overhead compartment. I watched people putting the backpacks and other items up there (and they did not pay). Additionally, nothing is for free on board- food and drinks will cost you (even a soda). The worst was not realizing you are assigned a seat (free), I got the middle seat (yay)! If you want to check in and select a seat, it will cost you $9 to $45 for any seat (they also do not recline)... Just crazy! My trip ended up costing me the same amount as a Virgin America ticket I passed up because it was too expensive."

Cons: "They charge more to carry-on than to check. By the time they made that clear, it was too late to check and they just threatened to raise it from $40 to $60 if I didn't act quickly. Everyone involved—from the gate attendant to customer service—has an impatient, condescending response about how these policy was made clear at the time of purchase. They are obviously very well practiced at explaining their ostensibly clear policies to throngs of ignorant masses who somehow didn't understand them when they purchased their ticket. In fact, their speech is so well rehearsed that you'd almost—almost!—start to question if they have actually made their baggage policies as clear as they think."

Pros: "The flight was punctual."

Cons: "I'm claustrophobic and was stuck in an aisle seat. My air vent wasn't working and I tapped the flight attendant, a woman in her late 50's to mid 60's, asking her to help me with it. She said she was about to give the presentation on safety procedures and that it was "more important than air right now." This happened pre-takeoff. I was upset about it and she never did help me with the air vent. Then, they do the service where they charge for everything and no one can get up to go to the restroom until they pass through, and they take a long time to do it. I was very unhappy, but kept to myself."

Cons: "Your check in on line is too confusing. Too much advertising mixed in with the check in process. Your food and beverage service SUCKS. No snacks or drinks unless you pay. Prices are rediculas for a drink. One little bag of peanuts or crackers and a soda is not too much to ask. We already pay too much for the ticket and luggage fees now we have to pay for a snack and drink. This may be my last frontier flight. And when are you going to get a better boarding system so I don't have to crawl across two people to get to my seat??"

Pros: "NOTHING"

Cons: "They cancelled my flight. Soonest Frontier flight they could re-book me on was EIGHT DAYS LATER. They have no agreements with other airlines to book cancelled passengers with. They would NOT pay any hotel expenses. It was left to me to find alternate transportation home as well as book a hotel room for the night and pay for it. This was the absolute worst airline I have ever flown on in all my years of air travel. Did I mention that they even charge for the in-flight soft drink? Oh yeah, The seats don't recline, none of them."

Pros: "The crew was very pleasant. The flight was the cheapest I found. The pilots on the round trip were very capable."

Cons: "The reason why it's so cheap is that they charge for everything. For some reason the site combined my first and middle name. I noticed when checking in and was prompted to change it. I was then showing a $400 balance even though I had already paid for my ticket months ago. I called customer service and they luckily updated it for me. The person then proceeded to tell me if I check a bag, bring a carry one, or want to choose a seat, there will be a charge. $60 just to bring a checked bag (27 lbs by the way) round trip. I opted not to spend even more money on the carry on and seat. I've seen other airlines charge for seats, but they're typically upgrades and you can choose another available seat for free. Not Frontier. If you don't want to pay the site tells you it will choose a seat for you. I don't know what the point of checking in 24 hours in advance is juat to be put in the last group no matter what. Speaking of seats, these were plastic, tiny, and uncomfortable. Speaking of uncomfortable, the plane felt like it was going to fall apart with even a hint of turbulence. Overall not great and I may have to go elsewhere for plane trips in the future. But that's up to Frontier."

Pros: "Nothing."

Cons: "Didn't like being misled on price. Charges for "a bag" and "a seat" were not made known until AFTER the reservation was made. Refer to the original business/pricing model. 1. Everyone has some baggage. Deal with it. Enforce carry on limits 100% and openly offer check bag at a reasonable price. 2. Seats are NOT a profit option. Seats are increasingly uncomfortable, cramped and added with premium charges. Finally, the travel experience should be a pleasant and memorable one, considering the time strapped in a seat. Its OK to have Coach & Premium seating, but stop adding "option pricing" for an increasingly poor experience. I will not fly Frontier again."

Cons: "Flight was scheduled to depart at 9:20 PM on the 24th. On way to airport, I was advised of a 5 hour delay. At that point I returned home (1 hour 15 minutes from TPA airport) by which time the delay advice was increased to 7 hours. I called Frontier and they agreed to rebook me (at no charge) on a flight on Feb. 26th since all flights on the 25th were booked. I just checked and saw that Flt 291 actually departed TPA at 5:02 AM on the 25th. As always, it was stressful trying to talk to an agent having to listen through numerous recordings before I couold connect to ascertain times and make changes. I contacted Frontier at least 5 times and had language difficulties every time."

Pros: "The plane is clean and the crew nice."

Cons: "I'm sure you get this all the time and you clearly have thought about it but when you add up all of the ala carte extras, then the fact is another airline would likely be better. I spend $16 on the seat and $40 on the carry on. Interesting nickel and dime concept for sure. But then I get to the seat and it doesn't recline. OK, that's fine I guess I only paid $16 for the seat. But what's with that thing you call a "pull down tray". You can't get a computer on it, even my tiny MAC. So I put my briefcase on my lap and I guess made my own little table. That's a bit much."

Pros: "All was on time, crew was friendly, emergency on board was handled well."

Cons: "The seats are not movable, so you could not lean back a little. No screen for entertainment, tray table was less than half the normal size, uselss, snack choices, had little that one might consider healthy. A lot of junk food, and a huge offering of alcoholic beverages. Could we maybe have healthier food. It could still be pre-packaged somehow. Cost of carry on: $30. Checked suitcase: $25. That did not really make any sense, other than they make more money that way. Also irritating that if you want to have a specific seat, rather than waiting for what you might get at the airport, you have to call them, and pay $13 for a seat reservation. They are nickel and diming you, or rather in dollars. It is a rip off."

Cons: "Arrived late. Baggage was overcharged. They charged me for carry on bag besides baggage claimed. Upon late arrival waited an hour till I got my baggage Arrived late. Baggage was overcharged. They charged me for carry on bag besides baggage claimed. Upon late arrival waited an hour till I got my baggage Arrived late. Baggage was overcharged. They charged me for carry on bag besides baggage claimed. Upon late arrival waited an hour till I got my baggage Arrived late. Baggage was overcharged. They charged me for carry on bag besides baggage claimed. Upon late arrival waited an hour till I got my baggage"

Pros: "Clean, comfortable plane. Pleasant and polite staff."

Cons: "When I checked in I had to pay for my seat - minimum $13 up to $35. I did not see an opt out option. Checked bag is $35 which isn't great but is reasonable. Carry on bag is $40 and "more at the airport" - are you kidding me!? One personal item is allowed but if it doesn't fit entirely under the seat you will be charge a fee "greater than $40" to change it to a carry on. My personal item did not fit and I was not charged for a carry on. Personally I would be very upset if I had paid for a carry on and seen people like me get around this. No free snacks or drink on the flight either. Frontier needs to be more transparent with their pricing and take a lesson from an airline like Alaska that gives free beer and wine on their flights. Their website is very difficult to use on an iPhone and the only option is to print the boarding pass - not to email it or add it to passbook. I do not have a printer so I had to download the frontier app in order to avoid printing at the airport. It is clear that Frontier Airlines is pushing the bounds of "calculated misery""

Cons: "Once I payed for the overpriced checked luggage fee and the hidden carry one fee and then had to purchase a seat on every leg of my flight, it cost me $166.00 to print my boarding pass. WHAT!!! Biggest scam I of airline moguls I have ever dealt with. Not only will I never fly Frontier again or never recommend Frontier to anyone, I will surely go out of my way to make sure everyone knows what a rip off it is to fly Frontier. I could have flown on a decent airline non-stop with a soda and maybe even a movie for what it cost me to fly frontier."

Cons: "We left early but then had to wait on tarmack for 10 min or so. More comfortable to wait in Memphis terminal."
