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 accommodation to the military service members!"
Cons: "Air fresheners should be used on the airplane."
Cons: "For options none. No drink carts at all. Had coffee once after I asked. Poor quality entertainment. Just a huge waste of money."
Cons: "The main economy seats were far too narrow."
Pros: "I always have a consistently good experience on Delta. Everything was great."
Cons: "My flight was delayed almost 3 hours. Not good. Once in the air it was fine."
Pros: "Everything ok. I was hoping to buy food but glad to see almonds as one of the free snacks. Delta seems to be upping its game a bit lately."
Cons: "No US carrier seems able to master smooth boarding without standing waits."
Cons: "1.5 hour delay...no reason given!"
Cons: "Flight was delayed and completely packed so our family could not get seats together"
Cons: "More leg room and seat width. I don’t like having other passengers pressed against me."
Pros: "Love the fact that the head rests move to support your head better."
Pros: "The seat was great, I wish all seats on the plane were that comfortable"
Cons: "Nothing, everyone was great"
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."
Pros: "The crew was great and super nice!"
Cons: "Screens with games, more leg room, and not having kids behind us messing with tray tables the whole flight."
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: "Not comfortable a little but scary on the flight to Detroit. Way better coming back to Denver"
Cons: "Better screens for in-flight movies. More legroom or upgrade options."
Pros: "Entertainment"
Cons: "Boarding at JFK.Always messy"
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. :("
Cons: "At least one hour late"
Pros: "Delta cramps people into these planes and forces you to put your bags under a seat because they stuff at the overhead spaces. They nickel and dime you for every single thing. There was even one person I saw who had to pay for his headphones to listen to the onboard entertainment. I think Delta should quit being so cheap with the profits they make and give it back to your flying customers. It borders on gouging."

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."
Pros: "Not much. Boarding by "zone" works ok, but is no quicker than most other boarding methods."
Cons: "Boeing 767-400ER seats had no leg room for 6'+ traveller like me. The entertainment system was so old that there were no 115v outlets or USB ports. On a 7-hour flight, that is a significant problem for travellers today with multiple electronic devices. Finally, we were not told in advance that we had to go through security twice and through US Customs BEFORE leaving Dublin. So, the 6-hour layover at JFK was a complete waste of our time as we did not have to go through Customs there."
Cons: "Very little leg room."
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: "The crew at the airport was very courteous and helpful."
Cons: "No food; not even offered water; I asked a Delta employee about our seats and she was very unprofessional (mind you I'm traveling with kids and my boarding pass said that seats were to be assigned at the gate)."
Pros: "The seats had plenty of leg room and the crew was was very kind."
Cons: "My seat was uncomfortable and I was seated in the only row of the aircraft without entertainment for a four hour flight. Then on top of that the passenger next to me removed his shoes and you could smell his feet from a mile away but the flight attendants never requested for him to replace his shoes."
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: "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: "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: "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."
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: "Crew was all very nice"
Cons: "Flying is always uncomfortable"
Pros: "When deplaning in Denver, I was impressed that the captain was the staff who got behind my wheelchair and offered to push me up the walkway :)... New aircraft, kind staff, shorty flight!"
Cons: "Nothing disappointed, butt i didn't have any good besides pretzels."
Cons: "Excellent service excellent pilot"
Pros: "Overall, the flight was very smooth and I thought the crew did a great job."
Cons: "I know this is a federal regulation, but I have to mention it as it is part of the boarding process. For the life of me, I can't understand why it is necessary to go through security again after re-entering the country. Understandable that I have to go through customs, but going through security again is ridiculous."
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: "long wait and delayed flight"
Pros: "WiFi, good flight attendants"
Cons: "Would like to see Direct TV along with Delta Suite so can watch live TV"
Pros: "One male attendant from the first class cabin - super sweet and attentive to our needs even tho we're not seating in the premium cabin"
Cons: "Junior attendants in economy comfort seat - so lazy and whiny!"
Pros: "From the Ground crew to the Flight crew, you can feel the genuine care and thoughtfulness of everyone! They even remember you, if you fly often enough, and let you know how much they appreciate your business."
Pros: "nice snack"
Cons: "We did not board at the scheduled time, although I believe we arrived on time. The crew was demeaning and singled out individuals who were causing the aircraft to not move. It was in a very pretentious manner, not like southwest personnel who have similar antics but with a playful tone. The plane is a small one where bags don't fit overhead and many head bumps occur. We arrived fine which mean the flight was successful but it was not very enjoyable."
Pros: "Left on time, arrived early. Great cabin service, attentive and polite. Comfort Plus seats are worth the extra few bucks."
Cons: "Nothing. Low rating for entertainment only because there really wasn't any, but I wouldn't have used it anyway, so no big deal."

There was no entertainment and again, the seats were very cramped and uncomfortable.

Pros: "The plane was really clean and they had lots of overhead storage."
Cons: "It was too crowded and cramped and UNCOMFORTABLE and there was a REALLY LOUD kid that would not shut up and nothing was done about it."
Cons: "On time take off would be nice"
Cons: "The Terminal in Chicago had no open amenities and overcrowded."
Pros: "The plane is amazing and the crew was very nice and helpful"
Cons: "Everything was all good."
Pros: "Crew was great."
Cons: "turbulence"
Pros: "I like the ability to watch movies"
Cons: "The cabin was hot... air didn’t blow well... the crew was abrasive and rude. I asked simple questions and got long explanations for no reason"
Pros: "Crew was excellent especially the first class attendant very attentive and always checking on you"
Cons: "The food needs to be back to normal for first class and also baggage is very slow almost over 30 min wait"
Pros: "The aircraft was very clean, neat and well maintained. The crew was friendly. Process of checked-in luggage was seamless and straightforward."
Cons: "I found the istructions on some restricted items to be confusing and contradictory between instructions at the airport, the AA website and the TSA website. The agent at the counter was well-informed, though, and it all ended up going well."
Pros: "Great crew"
Cons: "Nothing"
Pros: "Everything was great"
Cons: "Nothing"
Pros: "Crew was tight, friendly, flight comfortable & painless."
Cons: "The plane had a mechanical issue that they needed to address (due to the fact that they prior crew did not address it) and we sat in the gate for 2 hours waiting. No worries water was offered by crew and the flight had no food."
Pros: "On time flight. We were even a little early."
Cons: "Those seats are just crammed in there aren’t they?"
Pros: "The crew skipped me for breakfast and i had to ask for food."
Cons: "The food was not very good. Bread rolls stale and inedible. The rest of the flight was good."
Pros: "Pretty standard flight"
Cons: "Inconvenient timing and overcrowded with obnoxious children sitting on laps. No attempts made to change their behavior by crew or parents."
Pros: "Everything."
Cons: "Waiting for 30 minutes a Dublin to dock."
Pros: "Fine for a domestic flight. Normally, American Airlines offer a small snack to go with the drinks. But on this particular flight, they went the United way and offered nothing but drinks. Crew was pleasant enough during the flight, although they didn't greet half of the passengers entering or exiting the plane."
Cons: "Flight was a little late taking off and therefore getting to Denver. But there was no announcement about it. There was one announcement from the captain, but it was so soft that I couldn't hear anything. Upon landing and arriving at the gate, we stood there for a while with no lights on and seatbelt sign on, but no explanation of what was going on. There was no welcome to Denver message either. Maybe their announcement system was down."
Pros: "Outbound, it was on time, plenty of legroom, plenty of good snacks, drinks and food. An enjoyable flight. Score 10.0"
Cons: "Return flight - The flight departed 4 hours late. The seating was so cramped my husband couldn't move his legs at all, never mind try to sleep. The staff members were not smart in appearance, some with long untidy hair, and did not interact with passengers except to hand out food. The food was reasonable. We disembarked feeling like wrecks. Score 2.0"
Cons: "Our last 6 flights have all been changed or delayed significantly. Then they loose our bags on a direct flight. Won’t fly America airlines again!"
Pros: "Not using kayak."
Cons: "Worst flights in history. It took three days to get from Italy to the US. Do not use kayak!"
Pros: "Great service in first class"
Cons: "N/A"
Cons: "The flight was delayed. The food was not great. There is not a lot of space in these planes, and it was a long flight. There is no power supply."
Pros: "Eventually, the actual flight was fine."
Cons: "Initially delayed by 3hours (mechanical) which was American Eagle couldn’t get their “bucket of bolts” to Springfield, MO on time so we missed our flight out of Charlotte to Barcelona. Then we were rerouted through Chicago, but lost our first class seats and were bumped back to coach. This was after I had bought first class tickets for the entire trip only to be told 3 months before leaving that AA decided to switch planes on our domestic flight so there’s were no first class seats. THEN, in Chicago we tried to get first class seats on British Airways which would have been fine but After being sent to another terminal (after the bus to that terminal had stopped running) we were turned back because British Airways wouldn’t accept the boarding pass that AA had issued us. Now, having to go back to the first terminal to DISCUSS all this, we miss that flight and wind up stuck in Chicago for another 24 hours. Then, that flight was delayed by 3 hours, so we lost a day and a half of our vacation."
Cons: "3rd flight in two weeks suck sitting next to a morbidly obese person. They should be forced to purchase two seats."
Pros: "The crew was amazing - agreeing to work extra because it was Christmas eve and they wanted us all to get to our destinations for Christmas. They were very gracious and helpful."
Cons: "We were over an hour late to leave. I understand the reason for the delay because of weather. What I was disappointed in is that the delay was not announced until our actual scheduled time to leave. It meant people coming to pick me up didn't get the change information in a timely manner."
Pros: "Nothing!"
Cons: "I was traveling today with my daughter, who is 6 months pregnant, my 3 1/2 & 18 month old grandsons, my husband & son-in law on an international flight from Chicago to Manchester. I was very disappointed a 757 was used for an international flight! No attempt was made by staff to accomodate our family with a extra seat for the infant, even though there were a large number of rows with empty middle seats (4 of which were directly behind them!) The 1st indication of the beginning of the NIGHTMARE was when the plane arrived in Chicago and overshot the gate, this caused almost an hour delay! (We heard our crew saying "oops" while looking out the window at the plane arriving & then again when they were discussing it would have been faster if the plane had used a different method to get to the gate again.) This was then followed by a mechanical problem with a frozen water valve, requiring us to be de-iced x2! Then we started to taxi out and again had to return because of a hydraulic problem that required repair. I think we were delayed almost 3.5 hours. The crew did bring a round of water during the onground delays, and offered free drinks later in the flight. The icing on the cake was not getting the stroller back at the gate because there were no baggage handlers. I can't tell you how much FUN that was trying to corral a toddler & 3yr old with all our carry-on bags while getting thru customs! Did I mention in our haste to get off that plane we overlooked my daughter's winter maternity coat in the overhead! May be time to switch to the Friendlier Skies of United for our UK travel!"
Pros: "Nothing"
Cons: "I chose a package on the cheap flights that has a left hand side for choosing number of baggage which invariably inreases fare depending on the number of baggage and i choose 2 and paid for 2 baggage but the ticket came with 1 baggage and i contacted both by phone call, email and your website but did not get any fsvourable response. Had to pay again at the airport for the extra bag. This is highly unfair."
Pros: "Flight crew had a great sense of humor - they were extra friendly while boarding as well, made traveling with AA the best! Boarding was delayed due to previous flight but our pilot even managed to get us to Denver early! Wish I could have this crew everywhere I go!"
Pros: "The entertainment was good. Lots of choices. Food was about what I would expect for airline food."
Cons: "The seats were terrible. I don't know what it was about them, but I've never had a more uncomfortable flight. My husband had leg cramps for much of the flight and couldn't get comfortable. The rest of the flight was fine, but the uncomfortable seats were a huge minus. We'll probably try to avoid 787s from now on. The window-darkening system was annoying. They darkened the windows when it was dark outside and they darkened the cabin, so we couldn't look out the window. It was dark outside--why the need to darken the windows?? My husband requests window seats so he can look out the window."
Pros: "Flight was on time."
Pros: "it was fine. flight left on time and the crew was nice."
Cons: "that you have to pay $100+ for economy plus to get the legroom you used to get for a regular ticket."
Pros: "Friendly crew. Due to the apparent regularity of excessively delayed American Airlines flights, they had the staff at O'hare bring a cart filled with cheap canned juice and Diet Soda to lessen the blow of their consistently delayed flights."
Cons: "Like every other American Airlines flight I've ever been on, it was delayed. Including the American flight from Denver to Chicago. We pay entirely too much money to these airlines for them to deliver such painfully mediocre service and consistently delayed flights. I recommend that this airline do a SERIOUS audit of their Preventative Maintenance/Service division across their hubs. If I fly American, I would bet my entire checking account that the plane will be delayed well over 2 hours."
Pros: "It was on time. Crew were very good."
Cons: "Plane seemed very dated. No individual entertainment No USB chargers Not much space"
Cons: "The airline "randomly" selected me for extra security. Even though I have TSA pre-check I was jostled around, sent to multiple security lines without any reasoning and the local Chicago TSA and airport staff didn't seem to know what to do. Once it was figured out I was subjected to what was essentially a cavity search. Again I HAVE TSA-pre-check but apparently that means nothing if an airline flags you. It was an extremely upsetting experience but you were in a situation of either agree to the invasive search or get stranded over 1000 miles from home. I will NEVER fly Iberia again after a cancelled flight and being stranded in the wrong country on the way to my vacation and the horrible security experience on the way back. I seriously may never go to Chicago either after seeing the complete lack of organization and traumatizing personal invasion. I fly a lot for work and have never had such a horrible experience. I would really like to know how many terrorists are caught with these invasive searches and would love to know the justification for sticking your hands inside someone's pants and grabbing their privates after they have already gone through a metal detector AND the body scanner. Especially for someone who has already passed a federal background check to obtain pre-check status. Absolutely ridiculous."
Pros: "Seats quite comfortable. Crew ok."
Cons: "Pitiful food offering and no entertainment at all when on previous 1.5 hour AA flight choice of movies."
Pros: "I have nothing good to say about the flight to LA or the flight back to Chicago from LA."
Cons: "3 of the 4 flights were late, and the 4th was canceled. The canceled flight was due to weather, but AA's response was to connect those of us stranded with a 3rd party vendor - Travelliance - with the promise of a SUBSTANTIAL discount for a hotel (SINCE THE NEXT FLIGHT I WAS GIVEN WAS 17 HOURS LATER!) - and there was, effectively, NO DISCOUNT. I have spent thousands and thousands of dollars with you over the years, but this was a bucker of water in the face. I'm sure I'll fly with you again, but any sort of good will I held for AA is gone."
Pros: "we landed. flight was on time"
Cons: "Female flight attendants were rude. I think that if they would have smiled, their faces would have cracked. Even a complete stranger said to me, while waiting for the restroom, "I think that they hate us". One young male attendant was friendly and I believe that he was training. I fear for his training experience with this group of women. One of the lavatories was out of order {....on an international flight! Are you kidding!?!}. I think that they searched for the most antiquated plane that could limp across the ocean for this flight. Nine hours of pure discomfort. My poor 71 year old mother! Zero leg room. Tiny little screen for movies on the ceiling of the middle row. trays were not clean. We paid extra for our seats and wondered how bad the seats were for those that didn't. My mother and I determined that this was ranked as one of the worst flight experiences we have ever had. We are grateful for an amazing experience for our return flight or we would have reconsidered ever flying AA again."
Cons: "Missed that flight because my finair was delayed at Helsinki"
Pros: "The water was clean"
Cons: "Everything else! We were first sold a British airlines flight, and then we got switched to American Airlines. I don't know if that is actually an okay thing for them to do. When we got onto to plane we were stuck on the runway for over 2 1/2 hours, where the outside temperature was 95 degrees and the AC in the plane didn't work. The delay was all due to a mechanical difficulty with the engine, this did not give us peace of mind when flying over the atlantic. while up in the air my newly wedded wife and I were hoping maybe we could watch a movie to help keep our minds off the creaking of the wings, the pool of sweat from the delay, and the grumpy flight attendants. Seeing as it was a 9 hour international flight, you would have expected some sort of entertainment. Maybe a personal TV.... nope. Maybe a community TV... nope. At least they have to have a radio....... nope. All we got were our two thumbs to twiddle. After a much needed nap. We woke up hoping maybe for a hot breakfast, but to put the cherry on top of some terrible ice cream, we got a mediocre cold breakfast. All in all I will not fly American Airlines again. I would happily and quickly pay double for any other airlines but them. It's such a poor reprisentation of our country."
Cons: "Dry / borderline rude staff and hostess. Dated plane. Tiny seats. But that is pretty much the baseline of airlines in the US. When will carriers start to take note from International carriers..leaps and bounds ahead."
Pros: "Missed the flight. Money was not refunded."
Cons: "Nothing"
Pros: "More improved than the last trip I took with AA to Denver. Efficient boarding."
Cons: "My outbound flight to Manila had an overnight layover in Japan. I asked at the luggage check-in at O'Hare International Airport if they can check it all the way through as I had planned to go outside of the Narita airport for the layover. They told me I couldn't check the luggage all the way through and that I had to pick it up from baggage claim once I land in Narita. From there I had to check-in the luggage again on the same day. When I took my luggage out from baggage claim, I tried to check-in and the counter crew told me I was given wrong information. I had to keep my luggage with me until my flight the following day. On my return flight from Manila and another overnight layover in Narita, the check-in crew at NAIA told me I could check-in my luggage all the way through, and that they also allowed this at my outbound flight to Manila. The check-in crew at O'Hare International Airport gave me wrong information."
Pros: "Free checked bag"
Cons: "2 hour delay No food to buy or drinks"
Pros: "Eventually we made it"
Cons: "Plane was delayed because a door wasn't working (old). Business class entertainment was a tablet that was collected an hour before we landed. Food was very bland."
Pros: "Flight was on time through United since we had to be rescheduled from our original flight with American."
Pros: "Nothing. AA is the worst airline. Period."
Cons: "Rude flight attendants, delayed flight (as always), just AWFUL."
Pros: "Flight not entirely sold out. So they let my 14 month grandson have an empty seat between my daughter and I. That was a great gift since he doesn't sleep and is jumping and crawling all over the place. And I'm sure the other passengers were breathing sighs of relief!! Also super smooth landing and nice flight attendants."
Cons: "Flying with an active 14 month old toddler boy and of his "stuff" is nothing less than anxiety provoking. Not much the airline can do.."
Pros: "Entertainment system has a good selection"
Cons: "No earphones to listen to the soundtrack on the entertainment system"

Bad information from Kayak. unhelpful and confusing.

Internet was a bit spotty

Pros: "Nothing"
Cons: "Flight attendants passing out drinks completely skipped us, even though we were looking right at her."
Pros: "Nothing . Flight was cancelled"
Cons: "Refund my money!"
Cons: "main bag (out of 3; 2 made it) left behind"
Pros: "The flight was on time and smooth."
Cons: "Too many people with carry on luggage."
Pros: "Didn't happen"
Cons: "Didn't hapen"
Pros: "United delays"
Pros: "Stuck in Chicago. Never made it to Denver because of weather. Had to get hotel."
Cons: "Better accommodations by United."
Cons: "It sucked in many ways. But that wasn't united's fault. The weather was threatening lightning in Denver and of course because of that the world stops turning."
Cons: "It’s just crowded. The crew was great. Safe landing"
Pros: "Crew was nice and very efficient"
Cons: "Maintenance didn't have plane ready to depart on time"
Cons: "First flight of the day and there aren't enough floor assistants to address the sea of blinking red check-in kiosks. One poor soul is running around frantically trying to address all the check-in issues Pre-TSA doesn't start before our 5:15AM flight so after walking all the way down to the Pre-TSA checkpoint, we encountered a sign redirecting us back the normal tsa checkpoint which was overflowing with late check-in customers upset with the long kiosk check in delays"
Cons: "Placed in middle seat with no options for isle or window due to my ticket. No problem with that if the people next to me were not so big. Young woman to my left by window was tall and broad and slept but took up all elbow and shoulder space. Guy to my right was very obese, sweaty so kept wiping his neck, head, and face with a cloth. Also had terrible body odor. I spent the entire flight in a narrow middle seat, hunching my shoulders due to lack of space. Both people taking up some of what little room I had."
Cons: "We were delayed in Chicago due to weather coming home from Europe. We were not allowed to use the business class lounge even though we paid for business class tix. My family is still sitting in the airport waiting on their flight to dallas. We have been up now for over 24 hours. We should be allowed to be someplace comfortable for the price of the business class tickets. poor form on Lufthansa’s part."
Cons: "Delays"
Pros: "Helpful staff, hilarious video, smooth flight"
Pros: "Fast boarding and friendly staff."
Pros: "We had no difficulties and the crew was friendly and helpful."
Pros: "I will try to avoid Ohare in the future. Long wait to take off. Had to RUN to make the connection. Again."
Pros: "Everybody was very nice and the woman at the gate was very efficient at getting everyone assigned and through and up to date."
Cons: "Quarters were just very cramped. The seat wasn't quite padded enough so my hips began to hurt."
Pros: "Newer planes and pretty comfortable considering tight quarters"
Cons: "Disappointed that my seat assignments were dropped so had to go to gate to get middle seats."
Cons: "I want to clarify that I boough tiquests with Lufthansa not with United... and I had to travel United most of the time to Africa and Bach to the USA... united socks terrible ... bad food and old plain to cross the Atlantic... besides the service and the bad actitude of the employees... when I travel international I want only Lufthansa. So, kayak you tricked me ....horribly!"
Cons: "The boarding process is horrible. You have to stand in lines that disrupt the other people trying to navigate through the airport."
Pros: "The crew was polite and offered an extra six ounces of water in addition to the usual beverage service. The flight departed and arrived on time, which is a rarity when dealing with ORD."
Cons: "The cabin was near 80 degrees Fahrenheit for about 30 minutes of boarding. During the boarding process and taxiing, the DirecTV add ran theee times. The commercial was annoying and loud. Once would be enough."
Pros: "Was able to fly standby and get home earlier. Crew was nice and friendly."
Cons: "Slept most of the way, but this plane didn't have television screens, so limited entertainment options."
Pros: "Very windy decent into denver but pilots and crew were great."
Cons: "How they canceled one of my flights just as I landed at my layover for that flight when I look back at Boston they had a direct flight ready for my destination. Very poor management I was stuck in Chicago with no money or food for hours then after they start boarding for my new flight they tell me that I may not be able to get on even with ticket in hand. It was a joke and very stressful"
Pros: "The fact that priceline said there was nothing they could do."
Cons: "The fact that my pregnant wife and i were stranded in la guardia airlort and had to shovel out 800 dollars for last minute one way flights."
Pros: "Friendly crew."
Cons: "Passengers are stowing personal items/multiple bags in the overhead bins. This is an ongoing problem that needs attention. Armrest protocol should be made explicit. My in-flight entertainment control was covered by the passenger next to me the entire flight."
Pros: "United payed for the room and 20 bucks for food."
Cons: "Late. Missed the connection to Gillette and had to stay overnight."
Pros: "Did not make our flight to dickinson sitting in line in denver to make new flight. Only one flies into dickinson on sun and it's a late one. Will have to fly to different city."
Cons: "Delayed, missed connector flight to billings had to spend night in airport. Flight delayed 2hours to billings the next day. Worst flying experience ever will never fly United again!"
Pros: "Flight ahead of schedule. Friendly crew - got a full can of soda!! Good to see small snack reintroduced."
Cons: "Felt very cramped as was a full flight. No personal entertainment available, unless you paid for DirecTV."
Cons: "I missed my flight to San Diego from a connecting flight by a few minutes. Now I have to sit in the airport for over three hours waiting for my next flight.. not to mention it's my bday. Thanks United."
Cons: "Wish the seats were a bit more comfortable on frontier. And had to pay for carry ons. Will never ride frontier again."
Pros: "New, clean United planes! Happy crew! Snacks!"
Cons: "My boarding pass was not scanning which was holding up the line. A second person came over to approve me getting on the plane. That person made me check the size of my carry on bag, which had gotten bigger from some things I purchased in the airport but was just a touch too large for their sizer. She attempted to check the bag meaning I wouldn't have it until my final destination, which I was NOT ok with for two reasons. One was i had a 3 hour layover after this flight and needed work materials inside. The second was i was on a time crunch to get my ride at my final destination and was only traveling with carry on. She was very rude and insitant on it fitting inside the sizer as she stood over me with the tag to check my bag. I managed to take some things out that I moved into my backpack, which meant I had to awkwardly carry my blanket and travel pillow onto the plane. The most frustrating part was when I got on the plane, it was oversized top carryon bins, so the extra inch my bag grew would have been fine. Because of the time it took me to rearrange, i was the last one on the plane and all the bins had been filled with tiny second bags, but a few people on the plane had seen what happened and they rearranged a space for me. Also my video screen was broken and everyone else's worked. And there were two screaming babies around me the whole flight, but that is no one's fault."
Pros: "That we got a standby flight 6 hours earlier than our scheduled 12 hour layover. This plane was far better, newer and nicer than our international flight from London. UA929 was the WORST!"
Cons: "Snack chips don't qualify as food. Only water provided free. Out of all the star alliance members, United is the worst. We will try to not fly united again. Only entertainment you have to pay extra for. The international flight UA929 was the WORST. Old enough to all have the loop playing screens and mine didn't even work."
Pros: "Customer service"
Cons: "Delays. More than an hour and missing our connection in Denver which made us miss our car reservation and had to pay double for another car at the last moment"
Pros: "I liked arriving home in a timely fashion."
Cons: "The first gate agent responding flatly, "I have NO idea." to a gate change question. OR the Mother Superior flight attendants that couldn't wait to point and nag about seat backs and tray tables. I wonder if either of the women noticed they were talking to someone who wasnt't an English speaker? United needs to fly Southwest to learn the right way to do things."
Pros: "Crew was great and the boarding staff was very friendly."
Cons: "Flight was delayed"
Pros: "The flight attendants were all super kind."
Cons: "United is a horrible excuse for a company. 3 mechanical delays ultmately causing us to miss a wedding which was the reason for our trip. A 5 hour delay out and an overnight delay in the way home. We slept on the floor in the airport- one thing for us but disgusting to see United allowed this for elderly and families with toddlers and babies. The third mechanical delay occurred after we were finally bored and on the runway and they wouldn't let us deplane. Never have I been so terrified to fly."
Pros: "The flight is comfortable and the no hidden fees."
Pros: "The flight attendant finally took care of it after I complained a couple of times."
Cons: "That you changed our seats, and, that there was no room in any of the overhead bins. So, the flight attendant told me that I needed to fight my way through the people coming toward me back up the aisle and check every overhead bin all the way back up to see if there was room for my one suitcase. Others had brought more than one bag up there. Finally they checked my one carry on bag. The ride was also really bumpy, worst that we've ever experienced. But that was due to weather conditions."
Pros: "Well I liked that I got there and that the price for the flights in total was $190 (kayak SLAYED at getting me the right price). But I was expecting a continuation of excellent service that I got in white planes New York to continue, and be elevated, because they didn't have the same troubles that my previous airport did."
Cons: "There were just too many failed opportunities. The biggest was the gate agent who was "just filling in for another guy who's suppose to be here." I'm like well if someone is in line, even if they hop in line, you need to give them the best service because you're the face of the company."
Pros: "1st time I ever watched the safety/instructional video. Great job because it is important stuff and I saw others paying attention as well!"
Cons: "When the guy in front of me reclined his seat, there was no leg room. Today, I literally have bruises on my knees....ridiculous '"
Pros: "Had no problems!"
Cons: "Seats were very uncomfortable and very tight."
Pros: "Cheapest flight but your interface does not show all the up charges for basics like seat selection or a CARRY ON. If you book spirit you see these options"
Cons: "Be upfront abput all the upcharges and let people select what they want in the checkout process vs finding out at the airport. no on travels without at least a purse and they charge for that. Spirit does the same but you know that during checkout. Had no idea frontier did this with your interface"
Cons: "Check in"
Cons: "Avoiding the 40 minute taxi at departure, and finding better staff. We encountered the worst gate attendant and rude crew members who didn’t sympathize us traveling as a party of 7, with two young infants and one disabled adult."
Pros: "We got delayed because the plane broke down. Everyone else got $100 credit, but I didn't because I booked through Kayak. Could you please give me the credit?"
Pros: "Nothing"
Cons: "Everything. The staff kept lying about the fueling issue. They kept blaming the fuel tankers being frozen. They said 3 of them came, however i sat on the window seat and only one tanker came. After being delayed for 2 hrs and 15 minutes, when we got to cruise altitude they asked us for money for water. Are you serious? Also i was told that same plane will depart from Denver to Phoenix. I was told the same thing while in Chicago, during the flight to Denver and in Denver. It turns out everyone knew the flight left already from Denver to Phoenix. Needless to say, I won’t be flying with frontier ever again."
Cons: "We were delayed by 1hr and 45 min because a flight atttendant was not at the airport."
Pros: "Getting off the plane"
Cons: "Being in the plane"
Cons: "I had broke my phone coming from a music festival so i had no way to call them, traffic and construction made me miss my flight by 20 minutes and they would not help me get another flight or refund my money"
Pros: "Nothing was positive while using Frontier Airlines"
Cons: "Everything was pretty unpleasant: 1.) hidden baggage fees ($45 round trip would be one thing for a CHECKED BAG, but $90 collectively for the round trip is FRAUDULENT) Especially when most airlines don't charge for carry on bags or it's at least calculated in the final cost. At first when I booked this trip with FRONTIER $180 for my tickets looked like a decent deal, UNTIL I WAS TOLD AT THE COUNTER THAT I HAVE TO PAY $45 each way for a FRIGGIN CARRY ON BAG!! turning my reasonable and anticipated $180 trip turned into almost a $300 (NEARLY doubled my cost!) had I known I could have at least packed more into a checked bag for that price. 2.) my flight was delayed 4 hours on my outgoing flight, cutting into my personal time off and no compensation or even a kind gesture like a free McDonald's sandwich when you land...you guys really have poor quality and seem like you don't really care about the paying customer 3.) staff seemed clueless and didn't know how to answer customers questions as to why our flight was delayed!! 4.) mechanical issues with plane were the cause, or at least that's what the copilot or captain Just HAD TO MENTION TO US RIGHT BEFORE TAKEOFF, causing everyone to stir and raise eyebrows. 5.) to top off him mentioning the mechanical issues they were having with the plane the flight was rough..I've never been more tense or anxious on any of the other 30+ flights I've taken in my life. Pilot didn't seem to know how to handle turbulence."
Pros: "Crew was very pleasant. We were able to board easily. Like the newer seats that don't take up so much space so there is more leg room."
Cons: "Cabin was freezing, until one of the crew came back and adjusted it."
Pros: "Best Frontier experience I've had in a long time. Everything was very good and despite a delay getting the plane to the gate in Chicago, we were able to make up almost all of the time!"
Pros: "The price and schedule choice"
Cons: "They try to trick you into buying other things and speak in a condescending way on the website. There's no entertainment not even a magazine. The seats which are super ridiculously tight don't recline and there's no cushion for your head. You have to pay $3 for a soda and the batteries are so small you can barely fit which is great when there's pee all over the floor. The outbound flight was delayed over an hour with no explanation and perfect weather. When I asked for more water in the tiny cup, she poured it half way. I guess they are really trying to save money. Makes me wonder they took shortcuts on safety to save a few dimes."
Pros: "Overall quickness and friendliness of staff."
Cons: "No free food."
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: "Clean, efficient, cheap. Brand new aircraft."
Cons: "Ridiculously bare-bones plane. Seats don't recline. Tray table is insanely small - barely big enough to hold a Coke that the flight crew charges you $2 for."
Pros: "The Busch league pretzels I didn't get because the flight got cancelled."
Cons: "Not a fan of flights getting canceled with great weather on both sides and other Frontier lines taking off. Pay the extra for American; at least it will leave on time."
Pros: "I am sitting at the gate 4 hours delayed"
Cons: "Nothing what a disaster"
Pros: "Nothing"
Cons: "We were delayed and received no update prior to arriving at the airport. Our gate was changed suddenly just before boarding time and then waited an additional 30 minutes to board with no information. We then sat on the plane for about 30 minutes, doors locked not moving, again no information. I did finally receive an email update that our flight was delayed after we'd boarded the plane. We are now landed in Denver and just sitting on the plane not moving pushing 40 minutes, what a suprise-with no information."
Pros: "The price of the flight"
Cons: "The fact that frontier will not transfer checked bags to a different airline. If at all possible, I will never fly this airline again"
Pros: "Everything ran seamlessly, I even arrived early on my flight back."
Cons: "The seats seem to be getting narrower and make for a very uncomfortable trip."
Cons: "I haven't even left yet my flight has been delayed for 5 hours. No updates on flight status and all in all its been a stressful endeavor."
Pros: "Steamboat Springs, CO There were many CUBS fans on this flight! Good to leave rainy Chicago & arrive in dry Denver! Even though the plane was late, I was still able to catch my Alpine Taxi to Steamboat!"
Cons: "There should be a way to know when the bathroom is available!"
Pros: "O'hare airport."
Cons: "I was unable to print a boarding pass at one of the many kiosks - it informed me I needed to speak with a Frontier agent. The line for the agents was about 2 hours long, too long to wait to make the flight. After being told by a frontier employee that I'd just want to get in to the line to rebook on a later flight (9 hours later) I proceeded to speak with a momentarily vacant agent who, helpfully, printed and handed me my boarding pass. I arrived at the gate to a closed door and ended up needing to rebook anyway. I decided to just not go on the trip.... wasn't worth having to deal with Frontier 2 times in one day."
Pros: "I like averything about timing and been punctual."
Cons: "You have to pay for everything! The seats are uncomfortable. They should have at least free WiFi, so you feel the pain of the seats!"
Pros: "I really liked the brand new and updated Airplane. The fit and finish was quite nice and the electronics and lighting were nice."
Cons: "The crew was poorly trained in virtually all aspects of their duties. They had no coordination among themselves and ran around like a bunch of chickens with their heads cut off. One attendant yelled at a passenger at one point. They kept turning the lights on and off abruptly and made a HUGE deal about throwing away the trash because otherwise they will get stuck doing it all. The intercom system was also abused as the attendants made, at times foolish announcements, with a different attendant speaking almost each time. One would almost yell while another would speak very softly. The intercom system and speakers on this plane, particularly from the cockpit, when the captain spoke, sounded like it was from the Vietnam War era. For a brand new airplane, this was a disappointing shortcoming in the technology. We experienced excessive turbulance for the majority of the flight as well. I do not know if this is something the pilot is able to overcome but on this flight, it certainly was an issue as i almost had to vomit from all the very abrupt and excessive motion. I would not rate this as one of the better flights i have been on."
Pros: "Seats were more comfortable than I expected"
Cons: "Flight was delayed more than 2 hours."
Pros: "I got from denver to chicago and back to denver."
Cons: "The baggage pricing was unclear about it being only one way. The price difference between Frontier and others was quickly eliminated when we needed to pay for our carry on to fly home. We were also delayed on take off and landing both times and as far as I can tell on every frontier flight I have taken in the past few years. It has come to a head and I don't thing that I will be flying Frontier again, this was the last straw."
Pros: "Once the aircraft arrived at the gate, the crew efficiently loaded the people onboard, and we left very quickly"
Cons: "The fact that there were no updates, until the departure time was exceeded. It was apparent that 1 hour prior to the delayed departure, when the aircraft was not there, that it would be delayed. But no announcement was given to people waiting until after the 2nd departure time, and by that time people were pretty upset."
Cons: "Our flight was delayed, which I understand was due to weather and no fault of Frontier, but I was told, moments before I stepped on board, that my bag needed to be checked. I paid the full carry-on fee but was not credited the amount for having the bag checked. We were then delayed even longer on the runway. The flight itself was very rough and we had about an hour straight of turbulence. Then we landed and were stuck on the runway for an hour and a half! While we were stuck, there was a loud beeping sound that played the entire time we sat there! We received one update from the captain and flight attendants while we were waiting. The flight attendant came on the speaker and told us we couldn't move because everyone's seat belt was not fastened. They were very rude. I can honestly say that I will not fly Frontier in the future!"
Cons: "Delayed several hours, sat on Tarmac for 30 motionless minutes on departure and arrival"
Pros: "Nothing"
Cons: "I'm still on the damn plane. We've been sitting on the tarmack at the destination for 45 minutes. This is after we took off 3 hours after our scheduled time. It's 12:47 am and they claim they didn't have a gate ready for us. Is it really that busy after midnight? Um no. Frontier is just incompetent. Beyond incompetent. The "savings" aren't worth it. I wouldn't fly Frontier again if it were free. It's 90 degrees on the plane and they won't even give us water while we wait. It's borderline inumane."
Cons: "horrible accommodation theres a reason the flights are cheap they charge 45 bucks to check a bag so if u have to check luggage u might as well get a better airline. they had only like 3 gates at the airport boarding and exits u have to wait an hour and half on the tarmak. also flight got delayed and the didnt even say anything until it was our original departure time"
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: "Newer aircraft."
Cons: "Had to pay for sift drinks, sparking water, etc. No entertainment. Seats do not recline."
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: "The pilot was very informative and comical.It was a very pleasant experience."
Cons: "The seats are a little cramped."
Cons: "delayed two hours and were not kept updated, checked suitcase was torn when we picked up at baggage"
Pros: "New airplane"
Cons: "Should have been notified before heading to airport. No one wants to sit in a airport for three or more hours."
Pros: "nothing"
Cons: "the fact that i was delayed more than 5 hours on the departure and more than 1 hour on the way back. Why is there an option for entertainment when none is provided? Also you need to pay for the food"
Pros: "The crew was great. That's about it."
Cons: "The plane had to turn back in the middle of the flight due to a mechanical issue. We were boarded on a new plane relatively quickly so that was nice and appreciated."
Pros: "Animal picture on tail of plane"
Cons: "20 minutes into flight had to return to Chicago due to mrchanical problem. Then had to wait 3 hours in terminal before could board new plane. Got to Denver 3 1/2 hours after expected arrival. Then wasn't even offered something free to drink on new flight. Bad PR for airline."
Pros: "On time, friendly and affordable prices"
Cons: "Not very clean, the airplane was messy"
Pros: "The lady who got placed next to me."
Cons: "Getting onto the flight not actually having a seat or boarding zone on my ticket. Also the trays are completely useless. And the on board food and drinks are Way over Priced and wasn't offered until almost the end of the flight. Over All I wouldn't choose this Flight again."
Pros: "Staff was professional and helpful"
Cons: "Seats too close to each other. Chairs hard. Cleanliness marginal"
Cons: "Flight got cancelled, the trip I planned 2 months in advance and they said they couldn't fly me out till Monday and it was Wednesday, Frontier sucks"
Pros: "Good flight"
Cons: "Just remember, you get what you pay for. My flight was $148 from Denver to Chicago on Frontier."
Pros: "Initial cost of flight. Later disappointed that it was as expensive to check three bags."
Cons: "Seats were uncomfortable, mere plastic shells compared to other airlines and seats in our area did not recline. Very little legroom as rows seemed to be compressed. Being told we had to pay for checked or carry on luggage on-line so we checked three bags since we had to check one anyway. Then noting other passengers getting on the flight with bags they were putting in upper compartment without seeing how it had been verified that they had paid to bring on luggage to put in the overhead. I feel like a schmuck for paying for bags when it did not appear anyone was checking to see who paid and who didn't. Not even soft drinks were free."
Pros: "2 of 2 trips, over an hour late due to time sitting on the tarmac."
Pros: "Easy check in, we took one check in bag instead of three carry-ons and paid online to keep the price under control."
Pros: "I will never fly Frontier again. Poor customer service. Poor baggage handling. Poor timeliness of flight and baggage delivery. Poor communication of flight delays and baggage mix-ups. Understaffed. Undertrained. Poor seats, particularly considering I paid for the best. Inadequate compensation for 8+ hour delay and missing baggage for 3 days. After all the nickel and diming for seats, baggage (checked AND carry on) it would have cost me less to fly my preferred carrier and avoided every hassle, not to mention the inadequate compensation (again). Horrible, horrible experience."
Cons: "I will never fly Frontier again. Poor customer service. Poor baggage handling. Poor timeliness of flight and baggage delivery. Poor communication of flight delays and baggage mix-ups.

After all the nickel and diming for seats, baggage (checked AND carry on) it would have cost me less to fly my preferred carrier and avoided every hassle, not to mention the inadequate compensation (again). Horrible, horrible experience."
Pros: "Nice crew."
Cons: "Keep masks on travelers."
Pros: "Not much to like, the actual flight itself was ok."
Cons: "The flight was delayed over 6 hours before scheduled departure which changed 2 more times before boarding. The worst part was when we landed in Denver there were supposedly no gates available (although you could visibly see dozens of empty gates through the windows) and we sat on the plane 2 hours!"
Cons: "We were unable to catch this flight due to flight delay in Panama City. We are STILL at the airport in Fort Lauderdale waiting to get home."
Pros: "Not one thing"
Cons: "Seats are awful. No WiFi! No water! Have to pay for water!!? What!! Made me pay for my bag that I took for free with me to Chicago. Never ever"
Pros: "Staff were nice enough."
Cons: "Plane was over an hour late. Seats are too small and cramped and the man next to me had body odor. I know this is to be expected of a budget airline but it seems that airlines are going to crazy extremes with the size of seating."
Pros: "We arrived"
Cons: "Two hour delay with no reason why which is a really big deal when you arrive at your destination at 1 in the morning and you need to be up to baptize a child at 8 the next morning."
Cons: "You have to pay for food and drink which is extremely expensive if you don't bring something with you on the plane"
Pros: "Price"
Pros: "It was fine.. no frills so no expectations"
Pros: "I told the attendant that it was my friend's birthday and she sang happy birthday to my friend over the intercom. I'm sad that I didn't take the attendant's name...she was awesome!! Lively, funny and pleasant! She made our trip worthwhile, my friend posted the experience on FB!"
Pros: "I like nothing about it and the customer service sucked"
Cons: "I hated everything about spirit I was waiting at my gate for about an hour until they announced all last minute that our gate had changed and the flight was boarding when I went over to the new gate there was no one there and the flight had left! 8 people experienced the same thing and missed their flight. The manager who came to save us was rude and did absolutely nothing about it. I had to find another flight on my own and pay extra and reschedule my car rental and hotel reservations. By far the worst experience I've had at the airport please don't be cheap and think you are saving with spirit, they are a headache and worst service ever!!"
Pros: "Staff was friendly"
Cons: "No leg room and small seats!! I am a 5'5'', 120lb person and I barely fit in the seat and no room to put my legs. Can't imagine what a tall person would feel like!! No apologies for delayed flight and gate changes"
Pros: "Watching people argue with spirit staff! Kept me entertained for my 2 hour delay..."
Cons: "How rude and unapologetic the spirit staff was. It was their only instinct in response to their lack of knowledge to the situation."
Cons: "My flight was delayed by two hours due to weather, which is not under Spirit's control, but there was little to no communication regarding the delay. The online flight status wasn't updated either throughout the duration of the trip and so my sister, who came to pick me up, was stuck wondering what was going on at the airport for two hours."
Pros: "Boarding process was efficient and crew was nice. Flight was slightly delayed, but the pilot made the attempt to make up time in the air. I don't tend to recline my seat, as I don't like to cram other's space more than it already it. It was nice that no one could recline."
Cons: "Can they cram these seats any closer? Wow, I am certainly not tall, and trying to get my bag from under the seat was almost impossible. Super pricey bag fair for less weight when compared to other carriers. Be aware when flying this airline. They seem to be fair weather fliers. Any sort of weather condition, like snow, may cancel the flight."
Pros: "Boarding was relatively quick"
Cons: "It took an hour from when we landed to get to baggae claim. Waited over half an hour from when we landed just for the plane to pull up to the gate, very annoying and a waste of time."
Pros: "Nothing except the price"
Cons: "Delayed boarding"
Pros: "nothing"
Cons: "Flight was delayed, Woman had an intact male Pit bull as a service dog ( therapy dog). The dog acted up 3 times in waiting area I do not know why they would let that dog in the cabin?"
Pros: "Good fares."
Cons: "Lack of space. I am an average size male from the '50's and found the seating space very confined. I felt bad for my larger fellow travelers."
Pros: "The flight attendants."
Cons: "The delayed flight time and I had to check in luggage when I've done carry on with it before."
Pros: "Arriving safely."
Cons: "Being charged $50 for my one check on baggage after being told it would be $30."
Cons: "We were delayed for about three hours but there were no announcements or screens displaying that information. There was no indication that we were even at the correct gate. People had to walk up one at a time and ask to confirm what was happening and that we were all at the correct gate. Two hours after our flight was supposed to take off, there was finally an announcement letting us know that there was a delay and our gate would be changed so we needed to move out of the way so another flight could use the gate, but not to too far because they didn't know when or where our flight would be leaving from. It was chaotic and disorganized for no reason. I understand that delays happen but the lack of communication was unacceptable."
Pros: "Nothing."
Cons: "Customer service was rude, I immediately called once I realized I double booked and they wouldn't refund the ticket."
Pros: "Smoothest landing i have ever experienced and one of the only flights able to fly out in a snow storm on time no less!"
Cons: "Nothing"
Pros: "Crew was nice and on top of things."
Cons: "Seats were uncomfortable and at 5'7 not a lot of leg room."
Pros: "Crew, communication was all great"
Cons: "The only negative was the seats were a little cramped. I am not a big guy and I found the seating a little narrow. Overall a good flight, great value. Will definitely fly Spirit again."
Pros: "About the only thing that I can say I liked is, the boarding process went smothly for me & my luggage was on time."
Cons: "Where to start... paid more in bag fees & to get an isle seat for each(4)flights than I did for damn plane ticket! Flights delayed 4hrs another flight in same trip delayed 2 hours. Staff wasn't interactive/friendly I'd say 6/10 were nice. Asked for an isle seat the person helping at counter, said I'd have to pay to upgrade. Seriously- upgrade for isle seat!! I paid to have an isle seat on all 4 flights(I'm a disabled vet who was injured in the line of duty) I need easy access to toilets I'm unable to crawl over people, in turn need idle seat). Paid for isle seat all 4 flights- just to see the flights were super empty, people were sitting where they wanted anyway. Thanks for taking my $ for the seats tho spirit:-|. Staff wasn't that friendly compared to other airlines I've flown on. Not food. No entertainment on flight. Not worth it. If they don't do better business they won't last long I feel. There is potential just needs some work!"
Pros: "The price of the ticket. The choices in the flight times. Everything was on time and went well."
Cons: "Paying for every little thing including carryon, soft drinks, water, and all snacks. Seats were tight. Tray tables were too small to write a note on. Difficult to put items in magazine holder. I understand Spirit's goals but decreasing customer service is troublesome. I will opt for other airlines that do provide more amenities and pay a bit more in the future."
Cons: "Because of a large inconsiderate man, I was forced to use only a small part of my seat with half of my body including both legs and feet into the isle! Flight crew were well aware of my situation and chose to do nothing!!! My family and I would have gladly taken a different flight, but no option or solution was offered! I will be very sure to check all other airlines first on our next flight!!!"
Pros: "The process seemed rather straight forward and I was given a $50 travel voucher in return."
Cons: "I didn't like the baggage policy. I didn't like the check in policy or the fact that they don't support TSA precheck because they hope to sell you on an additional fee that will get you through a prority lane. I didn't like the seats which are hard plastic, close together, and don't recline. I didn't like the mini tray table that wouldn't support my laptop so I couldn't work. I didn't like that Spirit falsely advertises with the tag line "LESS MONEY, MORE GO" when the base fare for my connecting flight on this sub-par airline was more expensive than a direct flight on a better airline-before the other fees were added."
Pros: "It was an airplane that was able to fly to my destination....."
Cons: "Service, baggage fees, leg room....overall, it's simply not worth "saving money" with these inferior airlines, after baggage fees you would be paying the same for a higher quality carrier"
Pros: "I love the price"
Cons: "The seats, my flight was 2 hours, I wanted to take a nap but sets are so cheap made cannot recline and are uncomfortable. I will not fly spirit airlines for more than 3 hours"
Pros: "N/A"
Cons: "On top of the long lines, the flight was cancelled without any explanation 20 minutes before boarding. We were forced to walk all the way back to the airport entrance, but weren't helped at the Spirit ticket counter. Instead, we were given a card with a phone number to call in order to try and book ourselves another flight. We weren't able to get a flight until the next day with a different airline. It was a very disappointing experience, which created a terrible start to our trip. We will never fly Spirit again due to the unprofessional manner in which we were inconvenienced."
Pros: "Overall this was a bad experience. Spirit forces you to pay $55 for a carry-on bag. I suppose I should have known this already, and I'm sure it was in the fine print of my ticket. So partly my own fault. But when you add in all the fees Spirit nickel and dimes you for, you could have purchased a ticket with a better airline for same price. In addition, the boarding process was slow and the staff was unprofessional. The flight attendants were rude, the seats do not recline at all, and I could feel a hard metal piece inside my headrest. I asked for a pillow but the flight attendant said none were available. I will not be flying Spirit again unless there are absolutely no other options."
Cons: "Attendants were not pleasant, seats not comfortable, no options for good food, no movies"
Pros: "Easy check in. No frills. Polite crew."
Cons: "Website crashed when checking in and I had to call because bags did not get checked"
Pros: "I could buy the exit row."
Cons: "Gate crew was uninformed as to why our flight was delayed and could n't get that information. Boarding process was very slow given we were already an hour late."
Pros: "I liked that I eventually made it back to Denver"
Cons: "The fact that the delay was all based on Spirit not being able to properly maintain their aircrafts and gates. The hour and a half delay that ultimately made me late to work the next day was not even due to weather issues. I blame spirit for the inconvenience and this will certainly effect my future decisions to fly with spirit."
Pros: "Inexpensive price, great crew, the flight was to short for entertainment or needing food."
Cons: "Cramped quarters."
Pros: "The initial price seemed fair."
Cons: "The airline lets you bring a purse for free. If you don't realize this policy when you book: there is an additional fee for a carry-on. Unless you book through Spirit, this policy is not well communicated. Beverages-- including water are associated with fees."
Pros: "Our flight got cancelled about 1 hour after it was supposed to departure, due to mechanical issues. Since Spirit doesn't have many airplanes we were redirected to rebook our flight which would not get us anywhere until Monday morning, if we use Spirit. They did offered flights with other airlines, but of course those were gone fast. I missed a race, asked if they could refund at least part of that fee and was told no. Crew was nice, honest and helpful."
Cons: "The honesty of the crew."
Pros: "The flight was on time"
Cons: "Totally surprised to find out that I had to pay $55 to carry on a bag?No information provided about this before the flight. I found out when I was turned back at security. It made the total cost of the flight more than other, better airlines. The seats do not recline. You pay for everything on board including water. Not a pleasant experience at all!"
Pros: "The ticket price"
Cons: "That the seats couldn't go back but I understand tht part of keeping the prices low"
Cons: "The additional charges. Plus all of the talking, and people getting up out of their seats."
Pros: "crew is very cute and make funny joke , to make us relax, i enjoy a lots"
Cons: "check in luggage is too expensive."
Pros: "Flight attendants were nice."
Cons: "Seating was very cramped. Hidden costs everywhere, which jack up the actual cost of the flight significantly. Probably won't fly with them again."
Cons: "Waited for over an hour for a crew to get there to man the flight."
Pros: "On time."
Cons: "Seat and tray table were dirty."
Pros: "The flight seemed exceptionally smooth to me, including the take off and landing. Pilot seemed very experienced, competent and professional. I felt safe."
Cons: "Really? I can't get a free glass of water? Really?"
