Airline reviews

"We paid for preferred seating for extra leg room. On 3of the 4 flights the preferred seating were regular seats with no extra leg room. It was deceitful to advertise those seats at preferred seating. I would not have wasted my money paying extra had I known what I was getting."

"It was hard to hear the PA announcements for boarding. Maybe also post the info on the screen? Or allow the attendant to pull down his mask when speaking into the PA system?"

"Pilots found a smooth flight path! Wowza!!"

"Our favorite flights. Straight shots, with as much comfort as one would expect."

Cons: "No baggage space in overheads. Despite being in an early boarding group"

Pros: "For full plane went well"

Pros: "Excellent"
Cons: "Nothing short"

Pros: "NA"
Cons: "Informing that the flight would delayed by three hours ahead of time would have been amazing. Instead of extending the delayed time every 45 min making us miss all the other opportunities to fly out"

Cons: "100% as always.. delta has never disappointed! Keep up the good work guys"

Cons: "Better choices for food"

Pros: "Very courteous"

Cons: "Delta.... they’rrrrrr Grrrreaaate!"

Pros: "The crews were super accommodating and my seat was so comfortable I actually feel asleep which is something I have never done on a plane before."
Cons: "Load the plane from back to front. It makes sense as people leave the plane from front to back"

Pros: "Great crew, comfy seats and efficient boarding!"

Pros: "Most of the crew was great with the exception of curbside check-in in Denver."
Cons: "Curbside needs to stop chasing cash tips and do their jobs. If they focused on that tips would be easy to come by. The curbside attendant that took my bag didn’t even bother to check my id. He asked me my name and asked where my destination was. I told him Cincinnati as a layover then LaGuardia where he said that was wrong. He then proceeded to print a boarding pass that wasn’t mine and load my bag into the conveyor. Not 5 mins go by when I realize what happened I wound up having to go to special services to rectify the situation. Which ultimately consisted of me waiting another hour in LaGuardia to get my bag. Please delta have these curbside handlers actually want to do their job and stop chasing cash tips."

Pros: "Crew was very pleasant. Boarding and deplaning was smooth and easy!"

Pros: "Good services in anticipating our next leg"

Cons: "I would ask that the gate does not share in detail reason for delay in seat assignment is related to getting a family sitting together when the basic rules should apply unilaterally."

Pros: "The crew was good"
Cons: "The plane was extremely hot."

Pros: "Quick flight...ahead of schedule"
Cons: "Cheese It’s are boring...miss the snack mix"

Pros: "Good airframe."
Cons: "3+ hours delayed; didn't arrive until 3AM."

Cons: "Flight was delayed, for unkown reasons."

Pros: "Nothing"
Cons: "I bought a ticket thinking i bought it through kayak but I actually bought a ticket through a third party in India. Where no one spoke good English. I called the agency to find out if I needed a Visa for my visit to Australia and the told me no. So when I showed up to the airport I didn’t have the right documents and I MISSED MY FLIGHT. Also the wouldn’t just change my flight and charge me the change flight fee. They cancelled my flight entirely and made me buy a whole new ticket!!! Worst flight experience I’ve ever had and this is not my first time flying to Australia or out of country."

Pros: "It was water or water no soft drinks"
Cons: "Only water"

Pros: "Check in Denver super helpful Gate staff hustled to turn around flight Flight crew excellent"
Cons: "Flight delayed, almost missed international connections"

Pros: "The flight & landing were smooth, and we arrived a few minutes early."
Cons: "The entertainment system & WiFi were out. Wasn’t able to charge my phone either as the outlets weren’t functioning properly."

Pros: "Short flight"
Cons: "In SLC they boarded by row numbers and not zones. Weird..."

Pros: "I got to fly where I needed to go."
Cons: "The vents above my entire row of seats did not work, meaning there was never any air coming out even when they were fully open. This made for a long, hot, claustrophobic ride. The flight attendants seemed first disbelieving and later unconcerned that no air came out of our vents. I doubt they even reported them as broken after the flight. Delta's new boarding process is absolute chaos. More than half the plane had no seats assigned until 20 minutes before boarding, and the seats were displayed on a screen a good 25 feet away from the gate, meaning people had to constantly walk back and forth between the doorway and the screen. The gate agents were clearly overwhelmed. If this is how Delta is organized now, I won't be flying on them again."

Pros: "The exit row seat on this leg out of PHL to SLC did recline! No need for Delta Comfort+ unless you want to get off of the plane ... faster."
Cons: "For some reason, the pilot couldn't figure out how to adjust the cabin temperature for the first hour or so. This made the flight (and I was sitting in an exit row seat, right by the door which is usually cooler) uncomfortably hot and muggy. Food? No food. Thank goodness for Delta Lounge (even if it was the one in PHL). Just snacks make this a poor option for many. I don't know what is up, but the USB charger on the two monitors didn't work and neither did the outlet between the seats. And I have two different sets of cables "just in case" and they're the 3-in-1 so I can try to charge multiple devices (Apple, Android and Samsung) but nothing worked."

Pros: "Everyone was fairly friendly"
Cons: "Cramped foot room"

Pros: "Great people and crew early arrival nice passengers"

Pros: "Nothing!"
Cons: "Everything"

Pros: "Delta is great"

Cons: "Poor Delta DEN counter agent experience. Name on ticket didnt match Delta profile name nor TSA [rofile name. Delta counter agent would do nothing, except blame TSA. Would not check ticket name vs profile name. Happened two consecutive flights. Flight tomorrow morning has no TSA Pre clearance on boarding pass. This will be three consecutive flights. Also seated me next to a person who needed 2 seats to himself. Please never seat me next to a passenger who cannot fit in their own seat. I am switching to SWA."

Pros: "Able to download boarding pass into apple wallet"
Cons: "Flight was almost an hour late departing, bag is a carry on but storage too small to keep bag, then wifi didn't work the entire flight. Had to run to our connection since our layover time was taken up in Boise. If we had missed the flight, we would have been re-routed to another airport over 1 1/2 hrs away since ours closes. Next flight was not much better, oh and wifi did I t work on it also - last 3-4 delta flights I've taken have been late and didn't have working wifi - starting to think their system doesn't work at all - seriously going to take any other carrier but Delta going forward"

Pros: "Flight wasn't full so the service was very good lots of food and snacks and we arrived early too"
Cons: "Music was a. Bit limited"

Pros: "Nothing"
Cons: "That I couldn't reschedule due to the hurricane. I got stuck in Texas because of the hurricane. They didn't want to reschedule the flight because Denver was not apart of the affected area."

Pros: "Good Snacks, crew is friendly, toilet was clean and we arrived on time"
Cons: "Nothing"

Pros: "Great,I loved it!"

Cons: "Two overhead bins burst open during takeoff. it's pretty scared when luggage could potentially come flying at your face."

Pros: "Staff as always was very attentive and courteous. The board process proceeded smoothly and we were able to depart a few minutes early."
Cons: "One attendant did display a slight level of un-professionalism after spilling a drink on my mom and not apologizing. I chalk it up to her embarrassment and she probably just forgot."

Pros: "Entertainment options"

Pros: "Frequent food offerings throughout the flight."
Cons: "Boarding the plane was not easy. We had to show our passports to a man who quizzed us on where we were coming from, where we were going, and asking questions about our luggage. After that we had to go through another security point and scan our boarding passes, but most people could not get through with our boarding passes, so we had to get in another line to show our passes to our agent. It was very stressful since we were running late since the border control line was so long! While it was stressful, I am glad that they were careful regarding the security,"

Pros: "Loved the 757 layout with 5 first class rows and then economy plus to the left of the entrance door."

Pros: "Reassignment was pretty easy."
Cons: "No accommodations were available for overnight stay due to delayed flight."

Pros: "Free movies, lots of leg room, interesting for purchase food items."
Cons: "Food item selection limited - they only had snack boxes. The options looked interesting, but didn't quite taste as good as they sounded."

Pros: "Love the sofa and cookies."
Cons: "The leg room was reduced to the least I've ever seen on this flight. My knees hit and I'm 5'9'."

Cons: "I drove 5 hours to get to the airport and unfortunately ended up delayed because of traffic and slow shuttles from parking. I arrived 1 hour before the flight, but security was so slow I didn't get to the gat until 10 minutes before arrival. There were no gate agents present and despite banging on the gateway door and other Delta agents at the adjacent gate, no one helped me. I can only surmise that they had already given away our seats, which were award tickets, GAINED BY BEING A LOYAL DELTA CUSTOMER. The gate agents were unapologetic and useless at rebooking, and I bought a ticket from Southwest instead. As i was trying to get to my sister's wedding, and repeatedly told the agents this, their behavior was particularly abominable. DELTA, YOU'VE LOST A LOYAL CUSTOMER."

Pros: "I was upgraded to First at the gate. The crew was very professional and friendly. Food mini-minimal, but OK."
Cons: "On this A320 craft, old style, the First class seats are a joke. I had seat 2B. The pitch is apparently less than in the Comfort+ rows. The passengers in 1A and 1B started reclining even before departure, and during the whole flight. For me and my neighbor, with that seat on our chest, it was impossible to reach down to the seat-back pocket, not to mention to the bag stowed under the seat in front. To get out of the seat, I almost could not get my legs through the 5-in. interval between the back of the front seat and the irremovable armrest. I shook the passenger sleeping in 1B rather violently a couple times. The lady in seat 2B apologized, but she had to climb and put her feet on my seat to get out of hers, there was really no other way. Delta needs to address this ridiculous situation of their First Class seats urgently."

"I need to go back to waterloo this week"

Pros: "All was as expected, lights were out for a late night flight, and attendants were quiet and nice."
Cons: "Our flight was delayed by 2 hours, so that had it's normal difficulties. This was I believe due to the weather, and not a fault of the airlines."

Cons: "Nothing! it was great! I was especially impressed with the crew’s politeness."

Cons: "Nothing"

Pros: "Yes made sure mask was in place"
Cons: "No"

Pros: "Seats were great! No snackage... #covid19"
Cons: "Drinks"

Cons: "The plane was cold. The entertainment was mediocure. The staff was telling the people to get in their seats quickly as they had missed their scheduled time for take off. Yet, they 1st said we would board a little late because og clearing out the previous flight. And, no one could get carry-ons above their own seats and had to go back to then come forward. The attendants should monitor better what is brought onboard. I thought they were rude. And it took almost an hr to get our luggage at the carosel."

Cons: "Everything was dandy!"

Pros: "Our crew."
Cons: "Flying at supersonic sound."

Pros: "The seats were comfortable"
Cons: "Waiting to board took almost 2 hours ! We were delayed so many times and sat on the plane for an hour after boarding. I was supposed to land at 6:55 and didn’t land til 9:30 and I was late for work due to poor planning. The pilot even admitted in the announcement that there was a crew problem and maintence problem. I was not happy"

Pros: "Nothing."
Cons: "Everything"

Pros: "Nothing extraordinary, just solid positive experience from checking in on my phone thtough disembarking"
Cons: "I like the convenience of the built-in multifunctional screens (like on Alaska flights) that AA are lacking"

Pros: "We didn’t crash and die. That’s the only positive."
Cons: "Before we boarded I listened to a couple described how they always went ahead in line at boarding because no one ever stopped them. They described how they waited until group 3 was called and then went right through. While we were waiting, we watched them do it again. If you need to cram people into tiny spaces to be profitable, then you cannot allow them to make it worse by putting back their seats. I spent 90 minutes with a seat back jammed into my chest. We were ignored when handing out snacks, probably because we were invisible behind the seats pushed in our faces. It was one of the most miserable flights I’ve experienced."

Cons: "Rude crew member who yelled at me from across the cabin. I had stopped at an empty row to sit and look out a window. She yelled at me to return to my seat."

Cons: "It was cramped; it wasn’t overcrowded."

Pros: "Nothing"
Cons: "Had to change our plans, and AA wouldn't give us a refund. We never got on the plane but had to pay for the tickets anyway. I'll never fly AA again."

Cons: "You were out of earphones"

Pros: "We were allowed to board early with my father, who is disabled."
Cons: "Denver airport was a nightmare with my disabled father. We were given a “wheelchair” but no escort through a nightmarish security scene. Airport is terribly designed, lacking clear signage and navigation. TSA was a disaster and no one seemed remotely concerned about my father’s comfort or needs."

Pros: "Absolutely nothing!"

Pros: "Captain asked passengers not making close connections to allow passengers with connections to deplane first was very helpful."
Cons: "Flight left late and arrived late making my connection in Philadelphia for a flight to Budapest a very close call."

Pros: "Flight attendants were very good."
Cons: "Pilots need to do a better job of communicating delays. Especially the ones piloting this particular flight."

Cons: "The flight was delayed which caused us to miss our flight in London our family was delayed for 12 hours"

Pros: "Crew on the plant was friendly."
Cons: "I think at least some small food should be offer even tho it wasn’t dinner time."

Pros: "The plane was super comfortable"
Cons: "Long check-in lines in Denver - there were two sky caps outside who had no line which allowed me to reach my gate in time. Otherwise I may have missed my flight"

Cons: "Checked baggage untimely, causing me to miss the train"

Pros: "The flight was on time."
Cons: "The seats are absolutely horrible. I feel crammed like a sardine in the plane. Seriously, can we adjust the seat widths and distance to the seat in front and make them a couple inches bigger?"

Pros: "Great service, friendly staff. Plenty of in-flight entertainment options"
Cons: "N/A"

Cons: "90 mins late leaving LA caused us to miss connection from Brisbane to Darwin now delayed additional 12 hrs. LA Qantas rep lied and said every 2 hrs there were flights from Brisbane to Darwin and not to worry. Truth is only one per day."

Pros: "Food was good. Staff was polite."
Cons: "Both flights were late leaving. Plus then we waited on board for a long time. Once on board and waiting, no explanation, no updates. No idea what was going on or why. An announcement would have helped a lot. Philky-Prg: Long delays with food , staff was slow on the Philly -Prg flight. Seemed like they didn't want to be there. No info from flight crew. Phily to Prg - Crappy old plane that should not be flying over seas anymore. Applies to both flights unless specified."

Pros: "Good is that they sent you to Finnair to correct AA created break in service...why would they pay for it? AA is just an operator per itinerary! Why would you care if ppl get help with connections!"
Cons: "Checked in online on Finnair and automatically for the second connecting flight...and not the first -AA. So, had to check-in again for the first flight at the terminal. Board passes were printed 2 out of 3 by AA and both had errors - wrong gate for the first flight and no boarding info for the second connecting flight - just blank! AA did not provide connecting info until I found an unoccupied employee at the terminal and customer service lines were about 20 people in 2 locations I went to. The connecting info should be in the itinerary they said at customer service...nope, it was not there either!"

Pros: "seat"
Cons: "Staff seemed exhausted. American has no customer service phone to explain to customers what is going on. Bad experience all together."

Pros: "The crew on both legs were attentive, especially in helping people with connections deplane in Dallas. Boarding was easy. Checking one suitcase for free was good."
Cons: "the first leg of the flight was delayed. The information about when it would leave kept changing at the gate. I would have appreciated some extra food due to the delay... I was unable to get food in Dallas, which my scheduled layover time would have allowed."

Pros: "Good movie selection, there’s new titles available to see and it’s perfect for flight time from Denver to Dallas"

Pros: "Comfortable aircraft with an efficient and present crew."
Cons: "First, passengers had to wait in the main terminal for a bus ride to a remote terminal to wait to board. The only food items offered in first class were unhealthful packaged snacks. On a flight such as this, at 8:12 am, something like a breakfast wrap would be more appropriate, especially considering the fare charged."

Cons: "We had five pieces of luggage lost during our flight from the U.S. to Spain. When we arrived in Madrid we were told that all five pieces had been located. When we went to pick them up the next day there were only four pieces at the airport. We were told the fifth suitcase would be delivered when it was located. It's ten days later and there's no sign of the luggage. It has taken multiple phone calls to get the information about the luggage correct. They assure me that they have everything correctly documented and then when I call back they haven't changed a thing. It has been a very frustrating process overall."

Cons: "Escape row seat in a non-escape row wasn’t too fun or comfy. Took half the flight to connect to the WiFi to watch movies to discover that the selection was limited and poor selections at that."

Pros: "I hope I never fly American again!!! We were supposed to leave at 2.pm, but dud not until 11 pm. The AA customer service staff wanted to charge me $ for my carry on! We missed our connection of course! Had to wait 2 hrs at next airport for a hotel. Did receive food vouchers and luggage was checked in right away (good thing). But overall ridiculous! Missed an entire day due to AA not having another plain? Or not finding another way to put passengers in other flights."
Cons: "Customer treatment and lack of interest on custmer satisfaction. The Denver staff was changed so often they had no clue about customers needs and it was all about making the bucks for the airline."

Pros: "extremely friendly, smiling, and helpful service by the flight attendants, comfortable upgraded first class seat, timely arrival."
Cons: "No food service other than snack/ junk food."

Pros: "Nothing."
Cons: "First of all, the announcements that come on after we take off and last for 20 minutes is very annoying. We have brains, we can figure out how to plug our head phones in to watch the inflight entertainment. After saying the “show” was going to start, it never did. The screens were down the whole time and it remained black. good thing I had my phone with a movie on it, or I would be very bored for the 3 1/2 hour flight. Never flying with American Airlines again."

Pros: "The crew was friendly. Ticket cost was appropriate."
Cons: "Seats were HORRIBLY uncomfortable. I’m slender but tall and in my window seat my head hit the ceiling so I had to either slouch or turn my head to the side for the whole flight. In flight entertainment was awful (some weird sitcom loop) and the WiFi didn’t work with my phone nor laptop. Basically sat uncomfortably sideways with nothing to do for 2 hours. Flight also arrived late, causing transportation issues."

Pros: "Loved entertainment system need bring wireless headset however they will handout some later in flight."
Cons: "Seats were leather didn't let back air out."

Pros: "The America flights were all ON TIME."
Cons: "The seats on this particular flight were not as good for my back and they no longer offer pillows to put behind my back."

Pros: "Ease of boarding"
Cons: "That AA does not follow my preferences. I was assigned a middle seat even though my preference is an aisle seat."

Pros: "I like that American offers free movies thru their app but there was a glitch and I couldn't get it to work!"
Cons: "Couldn't get the entertainment app to work"

Pros: "Flight was good, there was no entertaiment, so i put one, but the flight was only almost 4 hrs. At night."
Cons: "I like the service I got and the service I got. I have back surgery and walk with assistance and the lady that helped me a the the birding desk took care of my needs and it was so much appriciated.. Thank you."

Pros: "Biscotti, pilot, crew"
Cons: "Seating is so uncomfortable, unable to recline more than an inch or so, then everybody rushes around making you return to an upright position! What's the point?"

Pros: "Great crew with an attention to details!"
Cons: "40 min late and a bumpy ride the whole time but good flight"

Cons: "The flight was delayed 9 hours for mechanical issues and they were not able to do anything. Since booking with Kayak neither Alaska airlines or American Airlines would help in getting us an earlier flight and both airlines said they couldn't help after repeated calls. Won't be booking any American Airlines flights throug Kayak again."

Pros: "The crew was very helpful at each stop even though they weren't responsible for the disasters."
Cons: "Initially we thought we were flying with British Airways. We then had to do some digging to realize it was all out of American Airlines. Then we couldn't get proper boarding passes and luggage tags until one of the crew members spent a significant amount of time untangling each leg of our trip so they were in the proper order. We got delayed by 4 hours in Chicago and missed our connection in Manchester. We had another 5 hour wait there. By the time we got to Dublin, our bags didn't also arrive. After almost 24 hours of travel, we arrived but without all of our stuff."

Pros: "Getting through security was a lot better than I thought. Also, I had plenty of room and the overall ride was smooth."
Cons: "I just wish that there was a little more room and easier ways to earn miles and entry into the lounge."

"Be on time"

Pros: "Na"
Cons: "Na"

Pros: "efficient, punctual"

Pros: "Staff was all friendly and exhibited positive and helpful attitudes. I also think the price and route was an excellent deal for this flight. It was actually such a good deal, it’s the main reason I even went."
Cons: "I think the baggage restrictions thing is really slimey and a shameful scam. I actually wouldn’t have minded paying around $50 more for my ticket and hand the bag included than be misled into thinking I could take luggage and finding out after it’s too late that I have to pay for my luggage. I think it’s a really sleazy business tactic (akin to resort fees). Fortunately for me however, I don’t travel with luggage so it doesn’t directly affect me. Still think it’s. Shitty way to do business though."

Cons: "I never got there."

Pros: "On time."
Cons: "Flight attendants were dis-engaged. No smiles. Not pleasant. RUDE to those wairing for bathroom. Not polite nor particularly helpful. Could not understand pilot at all. No one could dicipher his message. NO emtertainment without extra cost... on 4 1/2 hour flight!! Shame on you United! BOOO. Hardly anyone paid for entertainment. Very boring and hard flight. Will give another airline my $500 next time. Everyone who buys a cross-country ticket should get free entertainment. NO food except one cookie on 4 1/2 hour flight. Are you kidding?? I was starving! A small snack-meal was expected for the high cost we pay for ticket. BOO UNITED. UNTIL UNITED PUTS CUSTOMER SERVICE AND COMFORT FIRST... I and my family will be flying another airline. Very very disappointed."

Pros: "Nothing.... Seats were terrible!!!!!!!!"

Pros: "That they put my luggage on the wrong flight but at least they got it to me quickly when I got home"
Cons: "That I put my luggage on the wrong flight"

Pros: "Staff was friendly"
Cons: "United has a system glitch and we were delayed. I got in around 1 am instead of 11 pm. I decide to order a glass of wine and since they don’t give receipts. I found out i was charged for 2 glasses instead of one. To top it off the co-worker i was traveling with didn’t get charged due to the inconvenience and delay. i travel a lot with United (higher status than him) and would have liked that offer (and not get charged one i didn’t order) being a mileage plus and credit card holder. I did go on line and ask for a credit and they did make it right and give me a credit."

Pros: "I went to go talk to an employee about my flight boarding without me, when an Edwin Rodriguez of EWR New Jersey United Airlines employee started screaming at me. He told me to “wake up” and go run after my flight then while going after my flight he yells at me to come back. He apologized a few minutes later and then proceeds to yell at me again. My flight was canceled and reset for a later time. I have prior medical conditions that Edwin Rodriguez agitated through consistently harassing me at the help desk and am now in distress. I’m being relocated due to active duty military service and this is how you treat military veterans and their families."
Cons: "Edwin Rodriguez of the EWR airport in New Jersey. If I screamed whenever I didn’t get my way I’d be arrested. I will never fly United Airlines again because of Edwin Rodriguez."

Pros: "Chief flight attendant was nice and attentive."
Cons: "Our section of the plane was very warm. When we mentioned it to one of the attendants, she pointed to the overhead vents and told us to use them. (We already knew this and had them open all the way!) Then the chief flight attendant came by and she was VERY responsive and went to tell the pilots. It got a little better but still stayed on the warm side the rest of the way. Your boarding process makes no sense and does nothing to get passengers settled faster. After priority seating is done, let the people in the BACK of the plane board first, then the middle section passengers, then the Eco Plus passengers."

Pros: "Nothing"
Cons: "Our flight was delayed which caused us to miss our international connection. Flight attendants did not care, did not attempt to get us out faster, or put on a different flight. Asked for an announcement to be made on board or to be moved to seats closer to the front so we could get off the plane quicker, did not happen. Offboarded and sprinted across the airport for our international connection and was notified by gate attendents that the gate closed five minutes ago and that they could not let us on the plane. Meanwhile, the plane sat there for an additional 30 minutes while it fueled and waited for release from air traffic control. There were six travelers total stuck there in San Fran at that gate, all of us begging to be let on the plane to Beijing, the last one for over 24 hours. Zero compassion from staff at the the airline gate. They did not care about us and did not care about leaving their travelers stranded. Our total travel was Denver to Bangkok, 26 hours of travel including layovers in San Fran and Beijing. In San Fran (after missing the gate connection), United rerouted us through Haiwaii and the customer service agent that did this reroute did not finish the reroute to our final destination. We got to Haiwaii and were stranded again, at the United service desk for four hours having to once again provide documentation of our initial travel plans to Bangkok, having them build a new itinerary to our final destination. Overall, 20 additional travel hours have been added to our itinerary, almost double our initial travel time. We have had to call and cancel pre-arranged bookings in Thailand as we are now missing two full days off our trip. I am absolutely disappointed and heart broken as I write this still stuck in the Beijing airport waiting another six hours to connect to Bangkok. My fiancé and I were traveling to Thailand to get married and have received no compassion from anyone at this airline to try and get us there. I fly United for work quite frequently and have never experienced such horrendous service and lack of basic human compassion. I am flat out disgusted by United and will not be using them again, for personal travel or work related trips, because of this horrendous experience."

Pros: "Crew did a great job. Air China had much better food service."
Cons: "Seats two small, not enough room to stretch your legs. Bathroom to small. Designed for people less than 150lbs, and 5'-6" in height Not comfortable for people over 6' tall."

Pros: "The flight actually had hot food for sale! The cheeseburger was pretty good."
Cons: "I had a really hard time getting the cabin crews' attention during boarding for a piece of safety equipment. I hit the call light, tried to catch them as the crew was distributing headphones, and the light got turned off by an off-duty flight attendant without checking that we needed something. I got it in the end with an apology from crew but I still don't feel terribly safe Also, the paid entertainment system that my neighbors purchased seemed to be down with static for a portion of the flight."

Pros: "Seat 7 A on this type of aircraft - and United's configuration - had the most leg room and space, esp. when the seat next to you is empty. The flight crew was friendly and great!"
Cons: "Boarding gates/ area in Denver airport for these small aircraft was almost as bad as a bus station! Crowded and most cramped/ uncomfortable. Denver United staff at customer service center was most unhelpful, unsympathetic and dismissive about the fact that in spite of a flight delay that completely their fault (no weather delay), which made me miss the memorial service for my friend's daughter - my main purpose for visiting Cincinnati - they refused to even give me a patient hearing much less consider my request to try and put me on a different flight!"

Pros: "Pretty good crew but much less communication regarding flight and connection times."
Cons: "I wish the pilot would have told us what we were flying over!"

Pros: "The flight was good and we arrived on time, despite the fact we left Denver late. Didn't buy any food."
Cons: "The Entertainment choices on this flight were lousy...I also didn't like the fact that I had to buy Economy Plus because my wife and I were not only not assigned seats together after booking, we were not assigned seats at all. When I booked the flights I was only allowed to choose seats for the first flight - Charlotte to Houston...but not for the other three legs of our Charlotte to Seattle trip. The only two seats together from Houston to Seattle were in the very last row. And, on our return flight we had to purchase Economy Plus in order to sit together."

Cons: "Cant take carry on AND personal bag if im not premium member."

Pros: "The Captain kept us apprised of the delays in our flight."
Cons: "How the Denver airport has their gates set up for 77/78/79 and others, having to walk down stairs? then down a long hallway to go out on the tarmac to board the plane, then when having to deplane, repeat what we had just done in reverse, some customers were traveling with small children/babies, no offer to help these people were made, except to tell them they could use the elevator. Thought it was ridiculous that we had to go all the way to original gate when we were told we would be loading again on the gate next to the one we just came in from."

Pros: "Nothing"
Cons: "That my flight got delayed in Denver over an hour and I missed my flight from LA to BJX because of that. I was suppose to land in BJX At 6am on Friday April 28th for a family emergency and now my next flight isn't till 1pm! This is the worst flight experience I have ever had in my life. Never in my life will I ever fly with united again. My plans got ruined, I was forced to sleep on the cold dirty floor of LAX. This cost me a lot of time and money, and I am upset about it. I will tell all my peers about this horrible experience and encourage them to never fly with united ever again. I do expect some sort of compensation over this horrible experience."

Pros: "On time in spite of a late start Gate attendants were nice and helpful Comfortable as is possible in economy without spending a lot more money. Food (pretzels and drinks) as good as possible without spending more money. (I remember the good old days when you got much more in seating and food for your money)"
Cons: "This flight I had a window seat and I felt like I couldn't get up to stretch my legs or use the bathroom. (I am 70 and 4 hours is too long to sit) I usually get an isle seat but ALWAYS have to give up my bag at the gate - my bag which you tell me I can bring ON the plane with me. I do not like having to waste time claiming my bag that you told me I could have with me on the plane. I can pay $25 for that privilege!! The flight attendants always seem like they have their defenses up. One even held up the people trying to board so she could serve a drink to someone in first class. REALLY?? They couldn't wait till the plane was loaded?? I gave this flight a 'good' rating because it was mostly as good as it is going to get with economy passengers needs stripped to the bare minimum."

Pros: "Cute nice attendant."
Cons: "Pretty sad their old planes are way more comfortable than their new ones. Overall flights to get home were much better than flights out of town. Overall though, hoping to never fly United again."

Cons: "No entertainment and no where to plug in my phone."

Cons: "EVERYTHING. My flight was originally scheduled for 650p. I understand that weather can cause delays. That's OK. However, the flight departure kept getting shifted. We ended up boarding for a 9:58p departure. I was told there was no more overhead space for my bag and forced to check it. When I got on the plane at 930p, there was clearly enough overhead room for my bag. I'm not sure why I was forced to check it. We then sat from 930p to 958p. We pulled away from the gate and then were told that we had to wait another 20 min. We turned off the engine and then waited until sometime between 1130-45 ON THE AIRPLANE on the runway. Is this even legal?? We finally took off and landed at 115a PST. I waited for 35 min for my bag that they forced me to check. They loaded our bags onto the wrong carousel, which caused all of us to be waiting for our bags in the wrong place for 10 minutes. This was the worst experience I've ever had flying. It wasn't the delay but the lack of clarity, being forced to sit on that plane for hours, and having my bag taken. I got to the airport in Denver at 550p PST and got home to SF at 3a PST for a 2 hour flight."

Cons: "Customer service at united sucks like always. Hlped remind me why I fly SW or Delta."

Cons: "I think a whole can of soda is the least that should be provided for any flight."

Cons: "Upon approach we were suddenly deverted to Seattle. I had a few issues. Number one you could not hear the pilot so that made it worse. The lack of communication was horrible. I have been on flights when there has been clarity given a change in plans but this was bad. We sat at the gate for an hour and a half, again no real communication, the fligh attendant t hope was joking when he said there was a half a bottle left for the whole plane...much later we were served water. Announcements were made but no clarity. We were told to collect baggage at number 2. Get a voucher for a hotel. After deplann9ng about 25 of us stood in line at the customer service desk where there were two staff working slowly. Then after an hour they announced we were in the wrong place, couldn't that have been explained earlier? Once we made our way out of the terminal to the ticket count the line was all the way down the hall. still with little info we waited. We landed at the alternate airport at 945, at 130am I had my vouchers, the food not useful until the following day, the hotels were full, no one picked up the phone for the shuttle bus to the hotels. I finally elected to sleep at the airport on a bench. We had actually all been reassigned a flight on our same plane. So I am not sure why we had to wait in line all that time. Our bags were not removed from the plane an irritated baggage claim attendant told me. It was a mess. The flight the next morning was fine, short, without problems for me. united needs to work on its communications. It would have been helpful to have someone out side running the line giving out info. And at customer service they should have been paying attention to their line. Would have been helpful."

Cons: "I had problems my flight"

Pros: "Only good thing was the flight was fast and on flight staff friendly."
Cons: "Flight to Denver was supposed to leave from Albuquerque at 9:55. Screen said flight was on time. No rep at desk and screen changes to Houston and only way we found out our flight was delayed because the plane was diverted to Durango is because another passenger called United. Finally at a quarter till 11am the screen at the gate changed back to Denver but still said 9:55am departure flight on time but united's website stated flight delayed till 11:55am. Upon return to Albuquerque from Denver bag was not on my flight so I had to hang out in Albuquerque although, I live an hour away because I have prescription meds in my checked bag I need to take 4 times daily. Would not fly United again"

Pros: "Nothing to like. 6:00pm flight delayed and kept rescheduling takeoff. Boarded plane about midnight and after ninety plus minutes we were made to deplane because current crew was over their allotted airtime. Kept on plane awaiting a new crew but they couldn't get them so flight cancelled. Attendants told us we would be compensated for cancellation. A big airline like united should have a better grasp on scheduling flight crews and stand bys available instead of putting us through this hell. No hotels available so we all had to stay overnight in uncomfortable chairs with many sleeping on floors. I felt bad for myself as a 69 ur old woman with some health issues but felt even worse for the parents flying with little toddlers who just wanted to go home. The day of my flight Denver had 8" of snow that stopped by 9am yet I couldn't get a flight out till the following evening. Psp to Denver to Newark should have taken six hours but took me over 38 hrs of travel time. Denver should be used to snow and 8" shouldn't cause such extreme disruption at that airport. And united needs to better coordinate its flight schedules and working crews. I will be contacting customer service regarding compensation as cancelled flight was due to company musmagent. Finally it would have been nice if united opened its club to the travelers who couldn't get hotels. Sitting in a comfortable place would have been so much better especially to the elderly and small children traveling. Thank you"

Pros: "I liked the mobile app and everyone was friendly. I ended up being frisked by tsa, but they were just doing their job so whatever."

Pros: "I made it home"
Cons: "When I got to the ticket counter my reservations had been canceled by united. Worst part is the flight is now completely booked. I was lucky enough to make the flight thanks to a late flight from vegas where 7 people were connecting from but it was pretty stressful to walk up to the counter to be told the reservation you have had for 2 months was no longer reserved. This was one of the rudest staffed planes I've been on. These guys aren't over worked. I don't know why they can be so hateful. I loved united but this experience has left a sour taste in my mouth. It all worked out in the end, but I still can't follow why my flight reservation was canceled without me being notified. I shouldn't find something like that out when I get to the airport with my luggage in my hand."

Cons: "Never was able to make this flight. See above."

Cons: "Planes have mechanical issues, but they could have done more things at the same time like reboard while the post repair system checks ran and sort out baggage weights so that there weren't delays on top of delays. That was after not noticing issues with the plane until after waiting for late passengers and taxiing out. We arrived 4hrs late for a 3hr flight. They also only had one agent to rebook flights and assign hotels at the end even though they had hours to know the connections would be missed."

Pros: "the customer service rep was very professional and helped us out."
Cons: "my girlfriend and I were removed from the plane. she had received troubling news from her family that kept stacking on, not to mention we were tired from traveling all day thanks to delays making us miss our flights. and when we gestured for an attendant to come by, light dark skin, facial hair, glasses. he had customer service come by and we reiterated the question if we decided we would like to get off the plane would it be possible to receive a voucher for the flight. but we told him that we were just trying to consider options and we were good to go, and the customer service told us that the attendant did not feel comfortable with us on the plane, and that my girlfriend reached out and touched him and he did not feel safe. we never even raised our hands our eye brows. they caused us all kinds of hell, we couldn't get another flight till 2210, they embarrassed and humiliated my girlfriend because she was crying. unacceptable."

Pros: "The airplane was new and clean"
Cons: "The pre-boarding staff were rude and not helpful. I had requested an aisle seat when I booked my flight. Somewhere along the line, my seat was changed to a middle seat. When I asked the staff if I could switch to an aisle seat to help accommodate my sciatica, they told me, "sorry, we can't help you, you'll just have to ask another passenger." Neither crew member was willing to work with me or hear my concerns. So much for flying the friendly skies...well I guess we were still on land, so may that principle had not yet taken effect."

Pros: "The employees were very helpful on both legs of the journey and the conneting flights were conveniently located in the same area. Pilot was good about letting us know time frame of mechanical issue repair while on tarmack."
Cons: "The seats were incredibly uncomfortable. Must be the type of plane because never really had issues on other flights. We noticed many carry on bags others brought on bosrd were oversized. On leg from Kalispell to Denver the crew were diligent in spotting larger bags and tagging them for under plane storage for the flight. From Den to SFO however not so much. This led to most bins being filled ahead of our group 4 boarding with larger than permitted carry on bags. Obviously larger! Luckily we were able to put our smaller bags (which we made sure fit to overhead storage specs ahead of time) under the seat for flight but that made an uncomfortable 2.5 hour journey. Actually over 3 hrs because there was a mechanical problem which had us sitting on the tarmack for over 30 minutes from Den to SFO. We've flown United before without much incident but this trip in particular was pretty crappy."

Cons: "I Purchased 2 round trip tickets for myself and my son. My son had a change of plans and purchased another one way ticket to leave a week earlier. So his first leg of my purchase was not used. They resold that seat on May 27. So they made money Twice on that seat. Then when we checked in to return on 15 June. We were told his ticket had been cancelled and I had to purchase another ticket for his return. The flight was NOT sold out. My entire row of seats was empty. So I paid for 2 seats for the same flight. This is theft, coming and going and I am calling my lawyer!"

Pros: "The flight was on time, and the attendants courteous."
Cons: "However, the seats were so cramped, it was pretty miserable, even for just a 2 hour flight. With no snacks even offered because of turbulence, and no working wifi or seat back TVs, there was nothing to distract from how uncomfortable we all were. Plus, Austin's airport layout requires travelers to walk awfully far to get bags and then a rental car. Don't dare be disabled or feeling unwell--you'll never make it! Of course our gate was furthest from baggage claim, & someone's has to be. Nevertheless, it's a terrible layout, w/ pedestrians pushing through boarding queues and where others are lined-up to buy food."

Cons: "On April 15 we flew from Sacramento to Basel, via Los Angeles and Munich. We did exactly what we were told re reserving seats. We were told to call 23 hrs. in advance to reserve seats. When we tried to follow directions, we were not able to check in. Without checking in, we could not reserve seats. After numerous phone calls, to various numbers, we were not able to check in or reserve seats. By continuing to ask questions, to try and understand, we were told we were "under airport control". This was an "at random" situation and online check in was not available. Only 5 minutes earlier, we were still being instructed to check in online! We had never heard of this. I contacted a neighbor, who flies often internationally and within the U.S. He said it had happened to him once. He agreed that driving to the airport in Sacramento was a wise decision. This is not what we wanted to be doing 1 day before departure. At Sacramento we found a kind gentleman who saw our dilemma and checked us in as a favor. We saw assigned seats. He suggested we request to improve our seats the following travel day. It was a very challenging morning. As I tried to improve our seating the following day I was told, by airport staff, that this happened because we booked through Kayak? Rather with an attitude that we should have booked differently. This was a vacation we had looked forward to for years. I worked hard at not letting this difficult start damage my trip. Upon arrival in Amsterdam, I tried to learn more, to prevent a similar situation on the way home."

Pros: "I liked how the flight attendants treat people in this flight. Thank you all."
Cons: "N/A"

Cons: "I HAVENT EVEN GOTTEN THERE YET!"

Pros: "Everything. Great easy flight"

Cons: "Flight delayed 3hrs because there was no crew."

Pros: "Safety"
Cons: "Wish the problem with plane could have been detected before we were on the plane."

Pros: "I upgraded to first class so the food and service was very good. Loved the super adjustable lay flat seats."
Cons: "Even in first class, it was clear United doesn't care about repairing anything that won't keep the plane from flying. The entertainment console was damaged to the point it wouldn't even fit back together and none of the headphone jacks were operational on an 8 hour flight. We were also understandably delayed by a medical emergency onboard but United saw fit to further inconvenience the entire plane of passengers by searching the cargo hold for the the deplaned passengers luggage long after they were gone, rather than send it back on the next return flight. The crew said the decision came from corporate and clearly thought it was as ridiculous as we did. Given that United was valuing this seat at well over $2k, I think it's reasonable to expect the amenities to be in good repair."

Pros: "I liked that it was a direct flight from DEN to FLL at a decent time of day."
Cons: "I don't like being in Boarding Group 4 all the time. I don't fly United as often as I used to, but still it seems I should be able to get group 2 or 3 occasionally. I often have to travel with my suitcase carry on and it's difficult to insure I will get on at a decent time to get a space. My husband who rarely flies, but has a United credit card, gets Boarding Group 2 every time. This is frustrating to those who travel United still but can't seem to get a break on the boarding. It discourages us from flying United because of this approach. Charging for bags and boarding in the manner they do does not promote efficiency in the boarding process and only frustrates customers and discourages people from flying United. Changing their priorities would help both efficiency and make them a friendlier airline."

Pros: "Although the flight was delayed and the passengers were not happy, the crew were patient and helpful during boarding and flight."
Cons: "The constant delays, gate changes and late departure of the flight."

Cons: "The plane was an hour late! I was sitting with twins ten months old who screamed the entire trip!!! Having children I totally understand but the flight attendants acted like it made them angry instead of helping!!! I have flown United several times this year and there were problems on every flight! Lots of complaints!"

Pros: "The in flight crew was nice."
Cons: "The people at the ticket counter were rude and not helpful when my boarding pass wouldn't print. When I bought my airline ticket, I was not informed that I would have a checked bag fee, and it was expensive. The flight was late coming into Denver as well. The flight was delayed multiple times for reasons the airline would not tell anyone why. After we were able to board the plane, the gate attendants were rude. The in flight crew was nice, but they were not helpful with people trying to figure out seating. After everyone was on the plane, we were delayed once again. Once we finally got in the air, I tried to watch a movie. The movies were expensive also. The movie would not play for some reason. There was no leg room or room for me, or the person next to me. I would not recommend flying with this airline. This was the first time I have flown with them, and will be my last time. I don't like to write bad reviews but I have to with as many problems as I had with this airline."

Cons: "Frontier made me miss this flight"

Cons: "No allowing passengers in the back run to the front when the plane stops"

Pros: "quiet, no crowd, easy, early"
Cons: "light design on plane"

Pros: "Nothing"
Cons: "The flight was delayed twice after boarding, we had to sit in the plane for almost 2 hours. I dont think frontier is worth the price anymore, you definatley get what you pay for. I had to check a bag both ways because a checked bag is cheaper than their fee to carry on a bag. There were no complimentary drinks or snack even after having to sit on the plane for so long. I requested an aisle seat and got stuck in the middle. Overall, think I will be paying the extra for any other airline than frontier."

Pros: "I liked the fairs. plane was nice friendly crew"
Cons: "My wife and I didn't get to sit together No drinks, peanuts Seated next to a 400 pound women who had to used 1/4 of my seat"

Pros: "Nothing"
Cons: "Flight was delayed, then we board plane to have to get off and move to another plane and wait more than an hour before we actually left"

Cons: "Frontier fraudulently bumped us off our connection at Dulles and rebooked us on a connection 4 hours later. On arriving at Denver we found that the Frontier flight that we were originally booked on was still on the ground and had been held back. Frontier gate agent Sonia for the SLC flight was extremely rude. Lodged a complaint with the manager Rema who was not helpful either. Had to go through Security and rechecking in of baggage all over again, not to mention the time that we were robbed of."

Cons: "Flight was more than 1 1/2 hours late taking off after we had already boarded with only one update from captain explaining that there was a computer problem and he had no idea when it would be fixed but that they were working on it. When we finally did take off, we waited for an additional 30 minutes in Salt Lake while we waited for a gate and another 30 minutes to be allowed off after reaching the gate. Given the amount of time for security and early check-in protocol, I could have rented a car and only arrived an hour later to my destination without having to endure this flight."

Pros: "Great flight from start to finish. Had boarding passes, so easy, Quick luggage checkin, easy boarding, and easy, Quick luggage retrieval at end of flight."

Cons: "The ticket was cheap so of course we booked asap! Additionally you pay for your seat, some airlines there is free options, sometimes not. But with the price of your seat and ticket with any other airline, it comes with a free carry on bag and even some small free snacks on the flight. Nope. Pay extra hefty fees for small carry on, and of course pay extra for peanuts or even water. So after everything, it’s the same price as any other airline. At least delta has TV or United has snack options or American has decent leg room. Didn’t like either Frontier plane I flew on. Now I know for the future, it’s not as cheap as I thought."

Cons: "All of the unexpected baggage fees ($40 for a carry on bag? Really?) and fees if you wanted to pick your seat. You even had to pay for snacks and drinks that are always complimentary! And I have never sat in more uncomfortable airplane seats (they didn't recline AT ALL). Plus could they have made a smaller seat tray? Frontier is a joke of an airline"

Pros: "That my gates were close to exits. That it was on time. That flow was perfect."
Cons: "Liked it. Nothing didn't like"

Pros: "Crew was fine."
Cons: "Please forward this to everyone you know! Do NOT EVER fly on Frontier Airlines!!!!!! They are a total joke and charge fees for EVERYTHING!!!!! Want to carry on a bag or push everything you need into a small backpack? Oh, need to take clothes? Well that's $40...per carry on, $60+ at the airport. Oh, you wanted to sit down? That will cost you...$10 per seat minimum, again more at the airport. Btw, those fees only cover one leg of the trip. You can save by leaving your luggage there. See how helpful we are? You think you are getting a good fare but the fees have made my trip almost three times the initial fare. United is testing similar "economy" fares. None of this information is presented upfront so it's a bait and switch scenario. Also, trying to reach a human being is nearly impossible. I feel sorry for the customer service reps, they should get hazard pay. They have to try to justify these ridiculous policies. Save yourself money and frustration and NEVER FLY FRONTIER AIRLINES!!!!!!!"

Pros: "That I bought a ticket on a Southwest flight and will never have to fly Frontier again"
Cons: "Not flying home tonight"

Pros: "price"
Cons: "no customer service --- NO US BASED CUSTOMER SERVICE - - THEY DO NOT HAVE THE CAPABILITY TO SOLVE PROBLEMS --- THEY AE ONLY EMPOWERED TO APOLOGIZE"

Pros: "Boarding"
Cons: "Seat comfort , no water"

Pros: "The flight attendants were nice."
Cons: "After a 10 hour layover, they stopped the boarding process because a toilet malfunctioned and we had to wait another 45 minutes. The lack of complimentary beverages was pretty annoying as well, especially considering that after buying my tickets, I spent an additional $75 on checking bags as well as another $50+ to choose my seats at on-line check in. Of course nowhere did it mention that if I simply checked in at the airport instead of doing it online beforehand, I could be assigned seats and it wouldn't cost me anything. I drop $1000+ on airfare, checked bags, and sneaky extra fees, and you can't even give me a $.50 can of soda for free? I've flown Frontier before, but the customer service has gone downhill in the past few years. I will never use this airline again and I encourage others to do the same. They're providing an inferior service and staying in business by offering "cheaper airfair" which they make up for by tacking on exorbitant luggage fees, sneaky online fees, and neglecting customer comfort."

Pros: "Frontier is horrible"
Cons: "So many hidden fees. Frontier BLOWS"

Pros: "The flight attendants were cordial and funny. The ground crew was great to deal with too. The new airbus seats were comfy but lack entertainment and adjustments. The thing that irks me about Frontier is that every time we fly we have to pay for bags, whether they are checked or carried on. It makes the cheap flight deceptively more expensive compared to the other airlines and you have to pay for them separately. Lose-Lose"

Cons: "No real complaints about the flight, HOWEVER, Frontier's luggage handlers (probably in Denver) ruined a piece of my luggage. I got home very late and didn't notice the problem until the next morning. I checked their baggage policy and noticed there was a four-hour window to report lost or damaged luggage, so I was out of luck on a $100 piece of luggage. I recognize damage can be caused by any airline, but when you have to pay to check a bag AND carry one on, you would think you'd be given more than four hours to report a problem."

Cons: "I've never felt more taken advantage of by a company than I have for Frontier airlines. I purchased my ticket on a tight budget, only to find that the cost more than doubled from fees when I arrived at the airport. I was expecting to pay extra for a checked bag, but have never flown with an airline that also charges $40 for an overhead bag. I ended up spending more on luggage than my actual ticket (2 bags), which turned what would have been the cheapest flight option, into the most expensive. They also have a seat fee- yet another last minute slap-to-the face charge."

Pros: "At least I did not have to wait on the tarmac for 4.5 hours like I did in Denver."
Cons: "the aft steward was a power-hungry tyrant. He kept telling me to get into my seat which was occupied. When that could not be resolved, he told me to get out of the aisle so others could board. I was in the penultimate row and the people in my row needed to move to the last row. So who was I blocking from boarding? Also, the flight was extremely turbulent and not one seat in the last 4 rows had barf bags. As I deplaned, it looked as if 10-12 others did not have them either - - good luck cleaning that plane. The seats are sized for 5-yr olds. And lastly - you stick it to passengers with all the non-disclosed fees."

Pros: "getting off the plane"
Cons: "one crew member (aft steward) was a little tyrant. I was waiting for a seating error/confusion to be resolved and he kept harping to get out of the aisle and take my seat (which was occupied). He then closed all the overheads when we were half boarded - making new arrivals scrambling for storage. Also, all the hidden fees!! I paid 1 1/2 times my airfare in more fees. I'll fly another airline before choosing you again. I have flown over 500,000 miles in the past 20 years and this was the worst."

Cons: "See above"

Cons: "Seats sucked"

Pros: "Crew did a fine job."
Cons: "Booked over Kayak which did not inform me of the excessive charges for things like booking seats or carry-on luggage. In addition, the new Airbus planes have seats that do not recline, made of rigid foam padding, and tray tables that are smaller than an iPad Mini. There was no food or beverage without an extra fee. There was no entertainment. Frontier would be a lot further ahead if it worked with services like Kayak to report consistent cost of fairs compared to other vendors. The bottom line is that this is the last time I fly Frontier, and the last time I book using Kayak."

Pros: "The plane was clean, comfortable, and the crew was great."
Cons: "Everything has a price tag. Pay more for specific seats, pay more to select a seat at booking, pay more for carry on bags. No beverages, no snacks, unless you pay more. Last time I rode Frontier they had warm cookies. Now it is the most low budget, no frills airline still flying. Inevitably there will be credit card slots on the lavatories. Credit card slots to allow the seat belts to extend, and the O2 masks only drop if you swipe your card, yet again."

Pros: "We got to our destination."
Cons: "Seats are like sitting on a piece of plastic and they don't recline, which was funny every time we landed or took off they would ask to have the seats put in the upright positions. The minimal savings you think you are going to have go away quickly when you find out you have to pay for a carry on and pay for a checked bag. Oh and you want a soda and a snack on your 3.5 hour flight? better be prepared to dish out for them as well. When you are getting on the plane they have billboards going down the walkway that say Featured on Frontier and Showing soon on Frontier, but no TVs to view on. No place to plug in your devices to charge like the other airlines I use."

Cons: "Rude crew, horrible boarding procedure, late take off, later arrival, tell us wrong terminal for bag claim"

Pros: "I find it absurd they frontier charges you to choose a seat, they charge for checked bags and for all carry-ons."

Cons: "I contacted Frontier about a week before my flight to let them know my friend I was flying to visit had to make an emergency trip to see her father who was dying of liver failure. On the first attempt I was notified that only immediate family members were would be an excuse but that I could try to request through a different faucet of emergency circumstances. I put through another request and was never contacted. I did not fly to Salt Lake but I was still charged even though they could very well have sold my seat to another person and made double the money for the seat. I am very disappointed with the service I received from Frontier."

Cons: "I think I overpaid because your website is not clear about when you need to pay extra for your seat and one carryon."

Cons: "they didnt offer water on the flight. and before the flight on there website as I was trying to sign in they almost charged me 200 dollars extra, through just checking in. I have liked them in the past, but this one was not so good."

Pros: "There was no food and no entertainment. The flight was delayed 30 minutes. These are not criticisms, I did not expect food or entertainment, and delays happen. I'm just explaining the score I gave."

Pros: "The only thing that was bearable was the staff. They were pleasant enough and continually apologized for the massive delays."
Cons: "Both flights were delayed. The return flight was delayed by three hours. I understand things happen but rather than feeding me a line of bs about how it's only going to be "a little while longer" I would have rather have been told that the flight wouldn't board till three hours later. Because the flight was so late I missed my shuttle and ended up getting a cab which was an expensive toll I was less than pleased to pay. The plane seating itself is uncomfortable as all hell. Granted I'm 6'3" with a muscular build I could have chose a stretched seat but for a 1.5 hour flight I didn't think the extra fee was worth it. This and several other minor things have convinced me to never fly Frontier again so long as I can help it."

Pros: "Nothing."
Cons: "Pretty much the experience. I had a pretty lengthy layover to begin with. The delayed flight was absurd. It doubled my layover with little to no notification as to when it was going . It is was pushed back 5 times with no announcements from any Frontier employees. Plus once the plane finally ended up showing up, the gate was staffed with one employee that was seriously overworked. Everything was delayed again. Once we boarded the plane, there was yet another delay from the maintenance crew and there was no estimated time for departure. This seriously is making me consider never flying Frontier again."

Pros: "Crew was nice"
Cons: "That my luggage didn't arrive and the desk didn't have enough forms to fill outfit"

Pros: "The safety of the flight, kindness of the attendants and the cleanliness of the plane."
Cons: "The hidden fees. I purchased a ticket not knowing that I would then have to pay for a seat! How ridiculous is that??? Did you expect I would hold on to a handle like on a subway??? If I purchase a ticket, I expect that to include a seat. Your ploy to attract people to purchase tickets, and then charge up the nose for even a seat as well as a carry on bag and peanuts, is not impressive. I will not purchase a ticket on Frontier again and I will definitely let my friends and family know that they will be paying just as much for Southwest if they do so. I'd rather know up front what the total charges will be. Very disappointed in this aspect of my purchase."

Cons: "Hidden costs on everything"

Cons: "Hour delay - missed my ride home and had to take a ridiculously expensive can"

Cons: "Having to pay for a seat after buying the ticket. What were our other options? Standing in the aisle? And paying for a carry on? With all the "optional" add ons we would have been better off going with another airline that had more room, complimentary drinks, a real tray table that fit more than a phone on it, reclining seats, etc. Very disappointing. I will never fly Frontier again and will steer friends and family away from it."

Cons: "When I decided to pay for a drink-tomatoe juice, ONLY BLOODY MARY WAS AVAILABLE-yuk"

Pros: "The pre-reclined seats were actually quite nice."

Pros: "The staff was working very hard yet maintained cheerful attitudes after the previous day's wipe out of almost all flights due to a blizzard."
Cons: "Paying for a carry-on - really means that they are NOT competitive with other carriers. I was not aware of this and their other site (KAYAK, etc.) representatives need to VERY CLEARLY identify the carry-on charge policy. The time to process stand-bys was excessively long. It took over half an hour to process the stand-bys to allow our cabin door to close when we were already delayed 40 or so minutes. Also, 1) Notifications of delays were slow and 2) A warning to expect crowded ticket counter conditions would have been helpful."

Cons: "The seats on the flight had less leg room than most airlines. No free snacks, drinks, etc. Those for purchase outrageously priced."

Cons: "Very tight space and super uncomfortable chairs--no cushion and don't even lean back."

Pros: "When I got off"
Cons: "The entire flight"

Pros: "The flight attendants were very nice"
Cons: "I will not fly Frontier ever again because I don't like how they make you pay for every thing, a seat, carry on bags and even coffee. There's a lot of hidden fees. It's not worth it"

Pros: "Flights left early and arrived early. Boarding was done from the back. Crew was very professional."
Cons: "Extra charges for everything. They even charged to reserve a seat and for coffee. Really???"

Pros: "The crew was up beat and knew how to make you feel comfortable."
Cons: "Being charged $60 for a 2nd carry on, was not warned of this prior to ticket purchase. That the captain didn't warn the passengers how rough the flight would be, especially the take off into extremely turbulent winds. Scared quite a few on the flight. Was last off the plane, and still had to wait 30mins for luggage to arrive at baggage claim. I feel like frontier does the bare minimum to get by."
