Cons: "N/A"

Pros: "nice new plane, lots of room"

Cons: "No snacks"

Pros: "Yes"
Cons: "Good flight"

Cons: "Late 2 hours"

Pros: "I felt safe add respected. They serve drinks and small snacks, no meals going to Hawaii, plan ahead."
Cons: "The airport at Phoenix had little seating. I was funny in the floor in case someone needed a seat. Otherwise, everything was good."

Pros: "nothing"
Cons: "extremely racist crew made the entire flight uncomfortable for everyone."

Cons: "American crew and gate agents are awesome!!!!"

Cons: "more organized boarding"

Pros: "The crew was great"

Pros: "Flight was great"
Cons: "The AA crew at DFW are always rude"

Cons: "Need more space"

Pros: "everything."
Cons: "nothing."

Pros: "Prompt boarding and good directions from the crew"
Cons: "AA cancelled the Dallas flight before this one so they could fill up our flight. This does not seem very considerate of our health during a Pandemic especially with their messaging about social distancing. They also did a very poor job of keeping people patient in the deplaning process. They should have better messaging and a very non threatening way of encouraging passengers to be patient and courteous. Maybe they good offer each passenger a choice some type of goodie like a mint or a chocolate that says "please enjoy this while you wait for others to exit the plane"."

Pros: "They looked for 18 people to get off the plane because of weight restrictions and the process was very disorganized"
Cons: "Organization"

Pros: "Great crew."
Cons: "I would like the formal return of beverages and snacks. I understand the lack thereof is due to the virus. I think the airlines are doing a good job of staying within safety recommendations."

Pros: "Friendly, helpful and efficient."
Cons: "Almost had 3 people in a row...of people not in Same household. Luckily flight wasn't full so people moved around and made my row less crowded"

Pros: "Everything is good"

Cons: "Great flight"

Pros: "The fly was on time"
Cons: "No social distance has been practiced by AA very sad"

Cons: "Several people got on the flight with no face mask on. The flight was completely packed, there was no distancing at all. The boarding process required me to walk past everyone as my chair was in the back and I was last group to board (unlike other airlines that have switched to back to front boarding to reduce people coming in contact with each other) As I walked down the PACKED plane mot people had masks on incorrectly (hanging off one ear, down around their chin, nose out, etc.) some people had no mask at all and the flight attendants did nothing. It seems like they were doing nothing to keep passengers safe from COVID-19 spread. Compared to Delta, American Airlines was terrifying to fly, I find not feel safe at all."

Cons: "they filled the plane. Every seat. Even though there has been covid-19 fears. No other company has started this"

Pros: "The crew was awesome and boarding was quick"

Pros: "Crew was fantastic. They offered to valet my bag as I was boarding when they saw that it was cumbersome for me. The stewardess put me in a great seat when I was helpful to another passenger upon boarding. Also everyone seemed to be quite attentive and helpful during the covid situation, where people are a bit unnerved. I appreciated the effort to make everyone happy."
Cons: "The landing was a bit rough, but the rest of the flight was a dream. Definitely one of the better experiences Ive had in my 34 years of flying."

Cons: "Sat cheek to jowels in middle seat. Seems like a train wreck about to happen with Covid"

Pros: "Only masked picking up trash during pandemic - difficult to rate crew"
Cons: "Organized exit vs. usual crowded chaos of passengers in a hurry"

Cons: "Passengers need to DISTANCE 6' and keep their masks on. Which I realize is put of the hands of American. Appreciate the fresh white bag with a bottle of water and crackers. Thank you."

Cons: "Except for Ginette , the rest of the crew weren’t courteous or polite. Couldn’t wait for you to complete your meal to clear up."

Pros: "Boarding"
Cons: "Better seats, the main cabin extra seats were just like the other main cabin seats. One particular stewardess was very rude to all the passengers, while the steward Jeffery was very nice and friendly."

Cons: "I always have preferred American Airlines but they seem to have constant problems with the aircraft these days. This causes delays and missed connections. This in turn causes no breakfast or lunch or dinner opportunities. I travel with snacks in my bag at all times now just in case so I won’t get sick for lack of nourishment or water! This last flight I missed my connection altogether and had to take a shuttle home, then catch a ride back to the airport to pick up my luggage and then get my car to drive home. It was 4 hours past my expected time home."

Pros: "The trip started off poorly with a day delay and rebooking hotel and car at final destination. Not to mention our final destination is San Antonio not Phoenix. We were not rebooked for a flight from PHX to SAT. But after a few hours we were finally booked. We didn’t really appreciate the 7 hour layover at 0100 in the morning and nowhere to get a meal or even coffee. However, the flight had the same crew from the night prior and they were excellent. The flight was open so we were able to get more leg room, less waiting time for the bathroom, and pretty much one on one service from our flight attendants. With all the struggle in the beginning, this particular flight was actually the best flight I have been on."
Cons: "We were ok with the hotel and meal vouchers however, again, the only part of our itinerary looked at was the first flight, not the second into SAT. Had we not questioned the agent, we would have been stuck in PHX with no room, no car, and if we eventually would have gotten a flight, our reservations for car and hotel in SAT would have been cancelled and I would have been out $1700. I already lost money but it could have been worse. Basically, I am paying for a car and room that I am not currently in. Reimbursement for that would have been nice. Either way we will still travel using the travel service and this particular airline in the future."

Pros: "Not much crew stayed in back almost the whole 6 1/2 hr flight and seemed not to friendly"
Cons: "It would have been better if they had departed when they said they were going to after a delay. Flight was delayed first 1 hr then two more hours. The airline finally posted that it would depart a 4 PM and we didn't even start boarding until 5PM. Then they tried to rush us on so that everyone was standing on the HOT jetway for 10 min waiting to get on the plane. Plane didn't take off til 5:35 PM. Over all on this trip I had three flights that were delayed. I'll think twice before taking American Air again."

Pros: "The Flight crew was courteous and took care of us despite a series of extremely unfortunate circumstances."
Cons: "Due to a computer malfunction we were stuck on the tarmac for some time, when it was decided to find a new gate to return to. /The tech crew eventually gave the all clear and upon returning to the tarmac, the same computer malfunction occurred, and again we had to return to the gate. This was all totaled 2.5 hours on the Tarmac. Finally, some 5 hours late we departed Miami in a different plane. Upon arrival in Phoenix, the captain wearily announced that there was no ground crew awaiting us, so we had to wait some time on the tarmac there to disembark. Never before had I heard a airline captain encourage the passengers to write a letter of complaint to his employer."

Cons: "I arrived at the airport and had already checked in and had m boarding passes. For some reason they could not find me when I went to check my bag. After 30 minutes they saw that my seat assignment had been changed and that is why my boarding passes that I had printed at home did not match what their computer showed. I booked this reservation in May and had a seat chosen fairly toward the front. I am 73 years old and the closer to the front I can be helps. When I finally got on the plane to my surprise my seat was the very last seat on the plane across from the restroom. People continued to leave the door open after using the restroom so had to get up and continue to close the door or look at the restroom the whole flight. There was never any explanation as to why they did this. As a result, being lst off the plane, I almost missed my connection as I had to go two terminals over for my connection. At my age I cannot run so I arrived as the last people were getting on the plane. I will never fly American Airlines again."

Pros: "I fflew Delta last Nov. Had meals movies dinner inks etc. American I am serv d beverages no meals and no movies. Getting ridiculous"

Pros: "Room between rows Entertainment from St Louis to Phoenix"

Pros: "The gate attendants and on-board crew were lovely. Pilots provided info which was great and made up some of the long delay."
Cons: "There is not enough space to list everything. I paid $800 for a normally $300 flight, then paid an extra $75 for the ability to board early so I could store my very small roller carry-on. The in-bound flight was 2 hours late and even though I could track that easily, and assumed our flight would also be two hours late, the AA website insisted the outbound flight would be on time. So like everyone else, I went to the airport. And it wasn't until just before the original departure time that the update was indicated. Really?? If I knew the flight was going to be two hours late,that means AA knew, and didn't care enough about their passengers to advise them. Then when we boarded, my bag was taken away for gate check because the flight did not allow roller bags. After I paid extra. How can AA not advise you when you book your flight that roller bags would not be allowed?? Talk about a money-grab. I unfortunately have a return ticket and am not wealthy enough to throw it away and book on another airline, but I would if I could. I will never fly AA again and I will share my story far and wide."

Pros: "Nothing to like. If I could give them 0 stars I would"
Cons: "Tight connection from our previous flight yet the counter folks were rude and rushed us. My daughter is obviously 7 months pregnant. Because our connecting flight left milwaukee over an hour late, we had no time to even grab a sandwich, no problem we will buy food on the plane. Wrong! The food is was gone so quickly that by the time they got to us, they were out of everything. Oh did I mention we also had 3 children ages 2, 7, and 9. Oh yes and the entertainment? Small screens mounted on the ceiling of the plane. How about updating your equipment?? Plane was old. No USB to charge your phone and stream from their App. Terrible. We own a 2nd home in Maui and travel there twice per year. Looking at other options."

Pros: "VEry good Cabin crew and the plane was reasonable new"

Pros: "The plane was newer, drinks are available. Seat only reclines half an inch or so so get ready for that."
Cons: "Crew on aa is the worst bunch of entitled fools, almost as horrendous as united."

Pros: "The duration of the flight, nothing to do with the airline"
Cons: "I was forced to check a bag in when I had flown previously the week before with the same carry on. $50 spent for nothing in my opinion. Per the supervisor over head bin size does not change yet my bag was "too big" like I said I had flown literally 4 days before this trip and had no problems with my bag fitting nor did any of the flight attendants say anything. I am just annoyed. Also I didn't know that I would fly American as it's through Alaska originally, maybe that was my lack of attention to detail. The carry on situation is what irritated me the most. This is also not the first time that I've had a problem with American Air."

Pros: "Nothing"
Cons: "Nothing was together, missed connection. Had to buy a hotel in Phoenix"

Pros: "AA put us in a hotel and gave $12 (per person) food voucher for missed connection due to delay for maintenance."
Cons: "Our luggage was lost for 2.5 hrs in PHX airport, due to mix-up by service rep at customer service. AA attendant at gate at CLT was extremely rude and unprofessional when I accuse Left my boarding passes in seat pocket. Would not summon someone to retrieve it. Made me wait until entire plane was disembarked and cleaned, and made me wait some more after. She was super snarky, made rude comments, and almost made my family miss our connection to EWN. I will never, ever, fly AA again. Worst customer service and tons of issues with maintenance, luggage handling, and delays."

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: "Nothing"
Cons: "Delay, first told it was weather related, then mechanical. Re booked on a flight by AA that would never make connection. Paid over $1,000 for a flight leg that one way and direct on another airline (Alaska air) was $281.00 and the agent took so long to find redirect flight that they couldn't book. Total mess! While struck on the second leg and speaking with AA customer service about the reschedule I was told that they didn't have the ability to rectify the error because they no longer had control of my ticket and that I had to take into consideration that three was an event in San Antonio that caused delays network wide that added tio the initial issue... HOGWASH! 1) it was another AA issue where an AA aircraft drive of the runway while I was in flight on the first errant leg. 2) if they had just been straight from the outset, I wouldn't have been delayed. I will never fly AA AGAIN!"

Pros: "Airline and crew looked after us and kept us informed. My app said the flight was delayed but the captain didn't seem to know this so we sat for half an hour or more after planned departure. Maybe he hoped to get an earlier slot. We were 30 mins late in the end."
Cons: "No food for purchase, just a drink and biscuit."

Cons: "There was no food offered. The stewardess was not happy to be at work."

Pros: "Crew was fine even when we had to sit on the ground for 1 1/2 hours for a repair."
Cons: "American Airlines didn't honor my choice of seats."

"My trip Chicago to Phoenix was good. I slept most of the way. They charge for everything now. Carry-on was ~$50. I brought my own snacks. Seats close together ( well, it is an airplane), but luckily I’ve been vaccinated. It was a round trip and on both, the flight was delayed an hour. The delays were from lightening storms. It was ok."

"Flight 3 hours late. Moved gates."

"Seats are hard & don’t recline"

"The flight, crew and cleanliness was good, my main complaint is that they tried to charge for ANY and EVERY BAG bag, whether checked or carry on. So you think you are getting a good deal for flight tickets, but that cost does NOT include ANY bags. The very nice gentleman who checked us in ended up only charging us for 2 of our 6 bags. We had 1 checked bag and 5 carry on (1 for each of us traveling). So he charged for our 1 big checked bag and 1 carry on and then waived the fees for all our other carry on bags. This helped tremendously and was very much appreciated. Although, since we now know Frontier does charge for all bag types, we will probably avoid using them again."

"Frontier is a cheap airline but everything went well"

"3.5 hours late and took 40 minutes to get to gate after landing. Frontier is a mess."

"Leave on time and not wait for 40 minutes to be unloaded. Also I was throwing up for most of the flight but unless I wanted to call the paramedics, I was to stay in my seat."

"Experienced a 1 hr flight delay, but they kept u updated on changes. Very clean, new looking planes. Have to pay for any inflight food /beverages. Little leg room but ok for short flights!! Helpful, friendly flight attendents. No wifi onboard. Have to pay extra for larger carryon bag & extra legroom seats. But basic flight prices are good so will try them again!!"

"the flight was on time but boarding didn’t start till 30 + mins later so kind of delayed!"

Pros: "The wonderful crews and the comfortable seat"
Cons: "Snack and drink"

Pros: "Flight itself went smoothly and crew was responsive to people's needs"
Cons: "The check-in process for Frontier is a scam. Initial cost of my flight was $70, but they neglected to inform me of extra charges like carry-on and assigned seating until the time of Check-in, which upped my price to ~$130. Still not the worst price, but it was very scummy that this wasn't just charged upfront. Seats are uncomfortable, which led to many people getting up despite the seatbelt sign being on."

Pros: "The time was great"
Cons: "The seats are very uncomfortable especially when you’ve had back surgery."

Pros: "The crew they were awesome"
Cons: "All was good"

Pros: "Boarding was smooth. Extra legroom sets were way nice!"
Cons: "Give a snack and a drink for crying out loud!"

Pros: "I paid extra for a legroom seat on one of their newer planes. The plane was full so it still seemed very crowded in these COVID days."
Cons: "The people next to me ate a lot of food throughout the flight which required taking off the mask and discussing the food. It felt impossible to social distance more than 2 inches."

Cons: "Upholding mask expectations! Several passengers deviated without accountability checks by crew."

Pros: "Direct 3 hour flight! Easy"
Cons: "Bring on time but not a biggie!"

Cons: "Boarding could be better. It’s could be organized."

Pros: "For low fare it’s ok"
Cons: "It’s ok as we travelled as low fare"

Cons: "Good service"

Pros: "That I made it there in one piece."
Cons: "Not worth saving a couple dollars. Front tier airlines does not allow you to pick your seats before hand nor does it allow you to select baggage and the app, it is recessed for whatever reason. The seats are extremely tiny the tree table is so small you can barely fit an English muffin on it. There is no entertainment whatsoever, there is no Internet on the plane, and if you want anything to eat or drink besides water you will be paying for it. I’m sorry to say but flying on frontier was more like a punishment for me. I always fly American and wanted to save a few dollars what a mistake! With American most the planes that I have flown in have free movie entertainment and everybody seat the seats are comfortable And recline. And the snacks are free along with the soda. Please think twice before flying frontier."

Pros: "Do people write here for frontier?"
Cons: "Sat on the tarmac for over 3 hours. A fight broke loose and we had to return to the terminal and then back to the tarmac for more sitting. The crew finally figured out how uncomfortable and frustrated people were getting 2.5 hours to sitting with no air on the tarmac. They relieved their customers suffering then with complimentary water! Now that’s service. Frontier is one of the most base airlines out there. I’m entirely frustrated that they are one of the only airlines that service our podunk airport."

Cons: "Frontier seats are minimally padded and do not recline. It's difficult to sit in them for more than a couple of hours. Our 3.5 hour flight turned into a 7 hour flight after being unable to land because of storm conditions, circling for over an hour, and being rerouted to land at another airport for refueling before finally heading to our destination. It has been a week and our backs are still bothering us. We flew Frontier because it looked cheaper but after paying for luggage, seats, and food we would have been way better off to have flown on Southwest. We will never fly Frontier again."

Pros: "Getting off the plane."
Cons: "Missed my flight because lack of people to check people in. So slow. Waited 25 minutes. Figured I missed my flight since the board said on time. It was 2:25. Asked if I could get on 7:30 flight. Took computer 10 minutes for her to see and book. As I left, she said the 2:30 was still boarding. I said, oh, do you think I could still make it? She said the plane was still loading and running a bit late, but impossible to get on because I was booked on the 7:30 flight. I will probably not fly Frontier again. 4 hours later and $50 dollars in the hole for food and drink sitting here dreading my middle seat and no room to move for 2 hours. Then, have to pay for a Lyft to get to my car because my cousin was my ride back to her house. I sure do miss the old Frontier."

Cons: "Air bondage the seats were thin and uncomfortable they look like my daughters play school set .we were jammed in like crayons in a box .carpet , seats window Tray tables were a filthy and the tray table was so small , there was not enough room on it to hold a glass . The flight was 14 hours late coming in to den , plane broke down and do you they would help you ,,,nope your on your own . Missed a 70 th birthday party . I used to fly frontier exclusively the customer service wa great the plans clean with entertainment in the seat back . now it's like riding in an upholstered sewage pip With all the delux amenities of the DMV .by the time they up charge , you could have trvailed on real airline ."

Pros: "The staff that handled baggage was nice. Also, I liked that we made it safe."
Cons: "My flight was supposed to leave at 3:50...I got to the airport and went through security before I found out that my flight was delayed until 7:30. The flight kept getting pushed back. I waited 8 hours before the flight took off. There no outlets anywhere...leaving customers at a disadvantage because with our delay, our electronics were all almost dead or dead. There were no food options. We were supposed to get a voucher, and I have not received it. Lastly, after waiting over 8 HOuRS, we still had to pay for snack and drink. I was ripped off and will not be flying with Frontier again."

Pros: "The crew"
Cons: "Biggest regret buying this "discounted" ticket. Not a real discount. Found out there were a bunch of hidden fees when I was checking in. They charge $60 for the checked bag EACH WAY and was super shocked they charge for a CARRYON!! Unbelievable. None of the regular seats recline whatsoever unless you pay more hidden fees just to have your seat not be straight up the entire time, and there is no front table to put a computer. To save another dime, they installed some super cheap 6 inch x 3 inch mini ledges that they call tables. I'll NEVER fly with Frontier again. They also refused to let me check in early so I had to sit and wait for hours since they refused to give me a boarding pass until I came all the way back to ticketing exactly and only exactly at 2 hours before boarding. Worst flight. A total shame since the crew was incredibly nice."

Pros: "The baggage claim girl in Atlanta was Wonderful she was very pleasant to me and my boyfriend and expressed a genuine concern about my unfortunate circumstance. Mariah (Frontire baggage claim girl) did everything she could to make sure I got my Bag back and called as soon as it arrived Thanks Mariah !!!!"
Cons: "They lost my bags I was flying to Atlanta from Phoenix and my bag ended up in St Louis ... i would assume that if your going to make me pay for my checked bag it would atleast make it to the correct destination. The crew wasn't as pleasant and friendly as I'd like them to be but did there jobs (I guess) then we had to sit and wait for a gate .... the only reason why a gate finally opened up was because people started asking for snacks. Overall there was nothing special about this flight I was upset that I didn't have my luggage from the beggening of my trip but the day before I left my bag was recovered . The ticket was inexpensive but I'm not sure if it was worth the hasstle Then I had to pay for my bags coming back as well. Suggestion maybe have a 50% voucher ad a courtesy from sending a bag to the wrong destination."

Pros: "Buying their bundle through Frontiers website that includes a checked bag, a carry-on, a seat, and zone one boarding was worth it for this airline."
Cons: "The plane was definitely older and there was trash and something sticky all in and around my seat. The flight attendants were very stuck up and played on their tablets and phones for the duration of the flight, ate pizza, and looked to be drinking too. Not much customer help, but that's also because no complimentary items are given through frontier, no even a half cup of soda. There are no bonus features on board like wi-fi or tv's on seat backs to order tv or movies. The price of flight was offset by the cost of bags and seat, so I ended up paying the same as I would have via United. I will not be flyin Frontier again."

Pros: "Good flight"
Cons: "Seats not reclining"

Pros: "It was cheap!"
Cons: "It was cheap. You get what you pay for... I had forgot that there were absolutely NO additional frills with this airline... You get one cup of water and absolutely nothing else. The staff was a nice as can be expected, but didn't look like anyone wanted to be there. And when my husband asked for some hot tea (thinking it would be complimentary - it was not), they got very frustrated. But I would guess they're just victims of their circumstances, so no hard feelings... Still, wouldn't recommend unless you're on an extreme budget."

Pros: "The crew on the flight out of Detroit were pleasant and professional."
Cons: "The attendants in the airport at DTW weren't very friendly and throw luggage on the conveyor belt not taking into consideration people's belongings. Also the cost of bags and having to pay additionally for the seat is ridiculous. I would have rather pay a little more for a ticket for a nicer plane and be able to take my carry-on And my purse for free. I actually payed more with the cost of a ticket, bags and seat than a flight out with another airline. Both flights I took PHX-DTW and back were both significantly delayed. The seats were uncomfortable and tight. This is the first and last time flying with Frontier airlines."

Pros: "Likely the most uncomfortable plane I've ever been on. Seats feature zero padding, the inability to recline, and a tray table the size of a DVD case. I'm 5' 9" 148 pounds, young and very healthy. I left the plane with a twisted up neck like I've never had before. I landed safely so I MUST be thankful for that, but if I was booking I would want to know this information. Since I'm the wiser now I will not book with Frontier again. Also it was an extra $90 for my CARRY ON round trip. It notified me it would be extra when I booked online but didn't specify how much. What a surprise. I spent more on the fees for the bag than I spent on the bag itself (and most of the contents for that matter)."

Pros: "The flight was on time. The crew was friendly. They kept you informed throughout the whole flight."
Cons: "The fact that the carry on item cost me $35. There was no entertainment provided. No complimentary food or drink."

Pros: "I cannot be that mad because the plane got us there in one piece."
Cons: "Don't be fooled by the sticker price...Frontier was once a great airline but now they nickel and dime you for everything. The only way I will take Frontier again is if I am traveling with only a backpack and have no desire to eat or drink anything on the plane. I ended up paying over $100 on the day of because of bags and seat choices."

Pros: "I missed my first flight back to Phoenix and a sipervisor rescheduled me for a later flight. She was amazing and wonderful as there were no extra charges. She also helped me with handicapped transport around the airport. The man who got me from the counter to the gate stopped at a restaurant so I could grab some food as I didn't have any time to eat during the day. However all 3 flights were pushed back with the last over 2 hours late. I didn't get home until well after 2 am. Should have gotten home by 11:30 pm. Colleen"

Pros: "We landed safely"
Cons: "The flight crew was atrocious. They were rude when they spoke to us and when I asked for refreshments they turned around as if to get them for me and then the lady sitting next to my husband had to get their attention again to ask a second time if I could have water and Chex Mix so I could take my medicine. I have serious health conditions and I couldn't even get water without paying $3 a bottle. It is disgusting to me that we are charged for flight and then charged for Refreshments during that flight. Any other Airline who charges for a seat to take you to your destination includes at least drinks and nuts for free but not you."

Cons: "Tried to cancel this flight using the flight insurance I was up sold during checkout. Turns out that the flight insurance was only available for international flights? When I ask the agent why it was the recommended during purchase, she said I should have read the full terms and conditions during checkout. To me, this was a true scam. She told me that I could appeal the conditions of the travel insurance, but I would have to present a death certificate of the friend's baby that had just passed - the reason the baby shower was cancelled, and the reason this trip was cancelled. It was appalling. I tried calling Frontier directly, but their reservation desk was closed due to their system being down. HOURS I tried to call, and could not get a rep. I ended up not able to cancel the flight or even speak w a Frontier rep before my flight departed. In all, I was given 6 different numbers or lines to call to sort through this situation. All I did was waste hours of my time. This was a terrible situation where I feel like I was the victim of a scam."

Cons: "Fronteir created new seats that do not recline, are quite thin and small tray tables that don't lock. The consequence is that the man next to me couldn't lean back enough, so slumped onto me most of the flight. A one year old behind me constantly pulled up and down the unmatchable tray table and kicked my thin chair -- so I felt every little tiny foot. The stewardess refused to give us water when our row asked and they forgot to call boarding zone 2 when boarding so it was a mess. I would say Frontier was a terrible airline. Their discounted prices are a farce as they charge for a seat and carry-on luggage, so I may as well have paid for a regular fare from a more comfortable airline."

Cons: "The flight was delayed a few hours. It took forever to Get out of the gate. It took an hour once we landed to get in the gate and deplane. I was given a seat on the computer and then when I got on the plane there were two people with same seat. The floors and seats were unbelievably dirty as well. I have never seen so much trash and crumbs everywhere. It was an awful experience. Our trip to Vegas the first night was ruined because we were planning to see a show Thursday evening and landed two hours late and could have possibly made it but we sat on runway for an hour before deplaning."

Pros: "I didn't like anything about traveling with Frontier."
Cons: "Upcharge for Seats, Upcharge for Checked Bags, Upcharge for Carry Ons, Upcharge for Water. They charge you for water. That seems illegal. The flight was delayed, the gate was changed. We had to change gates which means we had to go through security twice. The staff blamed everyone and everything else (even the passengers) for all the issues and took ZERO responsibility for anything. I can't believe they are still in business with this level of customer service. The flight attendants were ghetto too. Making light of a bad situation by saying the worst things possible. Total embarasment transfer. I'll never fly Frontier again and will think twice about booking travel with Kayak."

Pros: "Co-pilot who had to explain to passengers why so many flaws occurred in this flight, she tried to be humorous."
Cons: "Flight 1884 out of SFO was doomed from the beginning starting with a notice (thanks Kayak) via email that the flight would be 1 hour late. Then, the Departure board at the airport totally dropped the flight, Then (again thru Kayak) I read that the flight would NOT board in terminal 1, Gate 21, Domestic terminal, but ar gate A3 in the International terminal. We all had to exit domestic and go to international and again through TSA. Then the flight departed another 30 minutes late finally over 2 hours LATE! Upon arrival at Phoenix the plane taxied too far away from the exit ramp-another 40 minutes before we could depart. It was an awful flight experience. Did they offer a free soda or anything for inconvenience we experienced-NOT A THING!"

Pros: "the crew made the best of a miserable corporate policy; the baggage arrived - 45 minutes after landing."
Cons: "2.0 hours late boarding; boarded 2x; lousy information; surly condescending station manager; insane baggage counter hours; no connection information in flight despite airline full responsibility for everyone on the plane being behind schedule.; connecting flight still at gate when 10 people tried to board and were not given access until a near riot occurred; no one seemed care at all. A woman with 5 week old child, a senior citizen with a cane, a woman recovering form surgery all RAN from gate to the other (about 1/2 miles) only to be told they were too late, the terminal door was closed. Only after pounding on the door, cajoling the customer service people 10 feet away and telling 50 others waiting in the service area did the door open!"

Pros: "The flights went fine, and were mostly on-time, just a little delay leaving Chicago because the incoming flight had to wait for a gate to open up"
Cons: "Frontier's customer service line is horrible, with no clear option to reach a person to ask questions of without hunting through every option. Also, they charged me to pick a seat, ANY seat, so what the hell am I paying for when I pay for a flight?! I also had to put my backpack under my seat, even though it was stated numerous times on their website that it would be too big, and I had to pay $40 to make it a carry-on, when there was no room in the overhead bins. Their customer service line AND website stated I could be charged up to DOUBLE that ($80) if I had to pay for it at the gate. I looked it up, and I would have payed less on at least two other carriers because of the extra charges. This is information that should CLEARLY be stated when listing the costs of a flight, not "covered" under "additional costs may apply" or some such legalese"

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

Cons: "I bought a plane ticket and then had to pay for a seat on top of that, as well as exorbitant charges for bags, and we ended up paying far more than even the plane ticket for all the extra charges. If I buy a plane ticket, that price is what I am expecting to pay. I understand a few charges here and there, but more than double what I expected to pay is completely crooked and terrible business. The plane ride was bare bones, uncomfortable seats, and average service. We will never be flying Frontier again."

Pros: "Except for my "complaint," I thought the flight was fine. People were helpful boarding the play. The crew seemed friendly and chatty. I had a good seat (upgraded to the first three rows for extra expense). The monkey white wine was good and the flight attendant was witty and helpful. Thanks!"
Cons: "The only thing that caused me some concern was that the ATL gate on the printed ticket read 1 but the actual departure gate was 1A. At first I went to 1 and the flight information said Trenton and I didn't see the 1A or even go there to look. I found a helpful Delta service personnel who said, "Oh these people, they are never around to help the passengers. I'll help you. He went online at a kiosk in the general hallway and pulled up the flight as departing 1A. Sincere there was no way for me to know about this. I could have missed the flight. Either post someone to direct passengers OR put the correct information on the electronic ticket. Thanks."

Pros: "The flight, the crew, the updates from the airline and Kayak was great. Frontier is a great company and very affordable."
Cons: "The airline increased the bag fees for the summer without an obvious communication. Very unfair and un professional from such a company. I paid $10 extra than 5 days before. The only problem with Frontier is that to check in bags there is only 1 maybe 2 people taking bags for full planes at least 100+ passengers. As it is cheaper and better to check in bags than carry on the airline should make this proccess more efficient. I spend at least 20-30 minutes to check my bag each wat ok my last trip. Very unefficient!"

Pros: "The Staff was friendly"
Cons: "the flight was only cheaper until you had to either check a bag or pay to carry on! Pay to drink a soda or anything! The seats are the most stripped down uncomfortable airline seats I have ever experienced. After all the add on costs, there is no value in the cramped, crowded, uncomfortable flight. Also, on every flight at least half of the passengers were not aware of the baggage policy until it was too late to check it for less money and had to pay extra to carry on. To top it off, we had to change gates at the last minute, resulting in having to go out of the Domestic terminal and sent us all back through the check in!!! We should have at least been able to fly through the pre check if not rerouted us through another way that did not require the total shoes off, open bags, metal detection all over again!!!"

Pros: "...the ticket agent who got me checked and put me through priority TSA so I could make my flight!"
Cons: "The assistance of a front counter agent was horrible and made inappropriate comments to me due to me being late to my flight which was due to a faulty shuttle and short staffed rental service as if I was aware of airline policy! Even though I wanted to avoid all of lines to check in (only carry on bag) but all kiosk where out of service which why the lines where so long...the snide remarks and rude comments were not appreciated especially in front of other patrons, thank God another agent to assist me after the line agent moved me another customer up due to our flights."

"I didn’t see a WiFi option . That could have been better ."

Pros: "Seats were very comfortable. Crew was very helpful."
Cons: "Allow me to use my ported and filtered mask."

Pros: "On time departures and crew was very professional"
Cons: "I wish that Spirit gave some kind of complimentary snacks/drinks for people that pay more money for the “Bug Seats” (like a business class style seat)"

Pros: "Crew was attentive and friendly"

Pros: "Even the cheaper seats are roomier than other budget airlines. More comfortable as well"
Cons: "Spirit charges for everything including soda"

Pros: "Flight from MSP to PHX was delayed an hour, which messed up our transportation down there. Minimal word was given, at time of boarding they then delayed 30 min, then when that time expired they added another 30. VERY UNORGINIZED, and unprofessional. Terrible service, terrible airline, don't be tricked by 5% cheaper fairs... they suck!"
Cons: "They canceled our flight home from PHX to MSP, they blamed weather in DFW, which is bull, there were many other airlines flying out of DFW that morning. Because they blamed weather, there was no compensation for screwed up schedules. The next available flight was 2.5 DAYS later!! no other options, it was ridiculous... they were no help to get rebooked on another airline, or even driving to another airport... horrible all around. We ended up driving to Mesa Gateway, flying Alegiant Air to Fargo, renting a car, driving 5.5 hours back to MSP to get our car, then 2.5 hours home again. But it's all good, Spirit refunded that leg of our fare... $220... we spent over $750 to get home by 1am, when we should have been there by early afternoon. DONT EVER FLY SPIRIT - THEY'RE THE WORST..."

Pros: "Comfortable with great low pricing"
Cons: "No free amenities"

Pros: "When he go down slowly so I'm not feeling nothing and that's very good Thanks"

Pros: "I did't board your flight again. I went to America airline. I didn't want to wait another 12 hours waiting for replacement plane."

Pros: "Brand new airplanes, and pleasant stewards."
Cons: "Over two hour delays waiting to board going both ways. In both cases the planes and cabin crew were on site but waiting for pilots. Apparently the pilots are suffering from 'blue flu' because they're not getting paid as much as other airline pilots, so they're intentionally calling in sick at the last minute. If the pilots keep this up they won't have airline to work for. Also didn't like that you pay for ANY luggage (even one carry on bag). By the time you pay for the add on fees your right back at the same price as other airlines. Then you add the time delays on, and your losing out. Won't be flying this airline again."

Pros: "Honestly, there was nothing to like."
Cons: "I can't give it a rating because they cancelled the flight and had nothing to book us on. Waited over 3hrs before they finally found me something. Gave me a hotel voucher but when I finally got to the hotel, they had no rooms. The transportation to the hotel cost a fortune because the hotel shuttle would not pick up the phone. They finally put me in a room with someone else from my flight. I got 60 min of sleep before having to return to airport. I'm a 49 yr old woman that flies often and this was by far the worst flight/airline experience that I've ever had. And, the lady at the hotel kept my food vouchers so I didn't even get to eat the next day."

Cons: "Canceled my flight to Dallas DAY of the trip just a few hours before. Big weekend (brothers graduation & wedding plus moms bday and Mother's Day) had to buy a new ticket through American... they were super nice but spirit was terrible. Riot/strike or whatever. So wrong."

Cons: "a $57 fee for a carry on is a bit ridiculous. If I had know this, I would have flown on a different airline for a little bit more cost."

Pros: "Nothing"
Cons: "When arrived I had to pay 10 dollars to print my boarding pass. I then had to pay $50 dollars to check my bag. I went to my gate and my flight was delayed. Not a big issue it was just delayed by 45 min. Once we boarded we sat there for about 30 to 40 min just to be told the pilot never showed. So they pulled us off the plane. We were then told that they had another pilot coming but it's going to be 2 hours. I was delayed 4 hours not beacuse of weather or plain issue but beacuse the airline could not keep there schedules in order. How did they not know a pilot was not going to show. How annoying it was to load on a plane to be pulled off again and loaded on again. Worst flight I have ever had and after all that they did not provide a complementary drink or even offer to refund my bag check beacuse of the huge mistake on thee behalf."

Pros: "The thing with Spirt is you need to read up on them a little as far as bag fees go and know why your getting such a great price. Once you got that down you Can find some killer deals and spend your money on the fun stuff❤️"

Pros: "it was sufficient"
Cons: "charged for bag at check in."

Cons: "Same as the the first flight. It might be good for someone on a short business trip without luggage but not for someone going on cruise."

Pros: "Nothing"
Cons: "Sassy flight attendant making stupid jokes. Flight attendants over served 2 passengers. One was sitting next to us and was almost incoherent so I'm not sure why he was even let on."

Pros: "Plane was new, cleaner, and roomier."
Cons: "Plane was old, seat (exit) worn out, cushion was short and hard, i.e. No cushion. Flight was Del aid, gate attendant gave no update as to why until 30 minutes after boarding time. And it was jetway attendant that made the announcement. Cabin flight crew looked tired. Cabin lines to bright during boarding and prior to landing. Plane needs to be retired, old and uncomfortable."

Pros: "Yes it was a great experience and a great price for the flight !"

Pros: "i have flown spirit multiple times out of phoenix in all kinds of weather and not once has it ever taken off on time! once the airline attendant even yelled at the passengers upon arrival at the gate like we were all children. I decided to check the status today instead of waiting in the airport for four hours and yes--- again it was delayed one hour and then two hours. so I planed accordingly and planned to be at the airport 1.5 hours ahead of the revised flight time. then they changed the flight time again and now I've missed my flight. this airline is absolutely the worst and I have flown domestically and internationally for over 35 years. I'm done with you spirit!"

Pros: "Honestly I didn't like anything about it. The flight itself was fine but charging for everything including checking luggage, $55, and carry on's, $52, was so expensive. I don't have issues with affording flying expenses but I don't expect to pay this kind of money without being informed when I purchase my ticket. NONE of this was explained in the purchase part of the ticket. I will NEVER and I repeat NEVER fly this airline again. I fly all the time for business and family related matters and have never had this type of expenses included in my flight. I am not a frugal person but this is ridiculous. Domestic flights will be only on airlines that do not charge for these things i.e. checking bags and pretzels for Christ sake. Spirit never! Thank you. Call me Chuck Fantastic."

Pros: "Pilot was friendly and updated passengers of every progress of flight."
Cons: "Steep carry-on fee"

Cons: "Seats are small and close."

Pros: "The fact that the plane and flight was on time. After our horrible experience going from Phoenix to Denver, we thought we'd NEVER use Spirit again. This return flight was a normal one and we might try them again."

Pros: "Hadto pay for my carry on bag..that expense was not expressed to me prior to check in and put me in a hole never flying this airline again"

Cons: "Being asked to leave the plane and the he flight being cancelled."

Cons: "We paid extra $60 for getting the wide seats in the front. Well, I can tell that we paid for be seated on the leftovers of the previous flight. Crumbs, papers, dirt and even full size nuts over the seats. Disgusting!!! I won't flight with spirit never again."

Pros: "The crew was sympathetic to us when we arrived with a carry on bag that we had no idea was a charge - they were nice and considerate about explaining Spirit's appalling charges."
Cons: "Spirit Air is so full of fraudulent business practices where do I start? You buy a ticket thinking you are getting a great deal, until you realize you have to pay for EVERYTHING: your carry on, your bags (OH, and they only have a 40lb limit, beware), your seat, and so much more. They are not helpful at check in and honestly don't want people to even have to deal with their agents (do it all online) and charge you $10 extra if you do need to speak to an agent. They are terrible. Food is expensive and they don't give you ANYTHING as a courtesy. I can't believe they are actually making money - but they do it because we all buy a ticket thinking it is a great deal only to find out we have to pay all the fees. I think KAYAK needs to REALLY consider if this is a business they want to promote as a low cost airline."

Pros: "The flight was great"
Cons: "The fees"

Cons: "Sprit did not charge anything for one personal carry on bag from Phoenix to LAX but on my return flight they did not say anything at aquiring boarding pass .When boarding was pulled out of line and slapped with a 100 dollar charge to carry my one bag that has fit on all overhead carry space for all major carriers that I have Never had to pay for the last 10 years"

Pros: "I went to the wrong terminal and ended up missing my flight. The people at the check-in counter said my seat had been given away, they could not reroute me with their computer system, and I had to call Reservations. I did so, was put on hold for several long stretches, and ultimately told that not only could I not get on another outbound flight without purchasing a brand-new ticket, but my return flight was now nullified and I would have buy that again too. Despite how distraught I obviously was, Spirit was unwilling to do anything to assuage the situation. I wasted an hour on the phone in the airport and ended up having to drive to LA through traffic on my birthday. A terrible experience. Never again. Will fly Southwest."
Cons: "Employees are not empowered to work toward customer satisfaction. Whether it's a computer system constraint or "policy" company line, Customer Service does not have the ability/inclination to solve problems and help customers."

Pros: "the flight attendant very funny"
Cons: "the 2 hour delay"

Pros: "Stewardesses very nice, nice plane. A little bigger than I am used to on these flights which I take quite often."
Cons: "Charge for carry on, charge for my spouse and I to sit together, which is ridiculous. I will not fly Spirit anymore."

Pros: "Your ticketing agent on August 6th was absolutely rude and nasty. My 8 year olds commented about her behavior without me prompting. Otherwise, the flight was wonderful."

Pros: "-"
Cons: "The flight was cancelled and they took forever to rebook us. We weren't given vouchers or anything to make up for the trouble. I won't be flying with Spirit again"

Pros: "Quick flight."
Cons: "No water or peanuts offered. Too crammed. Very small seats."

Pros: "The only part about this flight experience I enjoyed was the clever way the flight attendants did their introduction/safety announcement before takeoff."
Cons: "I waited in line to check in for 1.5 hours where they then told me I was too late and asked me to sign a piece of paper without at all explaining to me that my bag would have to go on the next flight. I am lucky I asked first because they had to make a special call for me since I couldn't wait at the airport for it at my destination. If I did not ask I would have been completely screwed up! I then waited in security for 45 minutes. My flight got delayed about 3.5 hours Total before actually taking off. I flew from LAX to PHX. I will never in a million years ever fly spirit airlines again."

Cons: "I checked in on my phone the night before and took a screen shot of the boarding pass once the "print boarding pass" automatically opened. After waiting in the security line at Denver International for 25 minutes I got to the front and tried to scan my phone on the TSA machine and was informed Spirit doesn't use mobile boarding passes (the one I had saved is not able to be read by TSA machine)! I had to go all the way to the ticket counter for a paper boarding pass and almost missed my flight. It's 2016 and Spirit does not use mobile passes...so lame."

Cons: "I never got to Phoenix via spirit. Instead I had to buy a $400 flight to get to Phoenix. The guy I spoke to on the phone was rude and kept placing me on hold every 2 minutes. I've literally never had a worse experience flying. Spirit needs to figure out how to not cancel your flights since this trip alone o had 2 cancelled on me."

Pros: "Nothing"
Cons: "Our flight home was cancelled "because the pilot didn't want to fly" on an 11pm flight. Chaos ensued and we ran for the ticketing gate. We arrived 4th in line. We were assured we would be ticketed "in order" and we had asked for the earliest flight back. Needless to say, we were NOT given an early flight, yet others after us were. There was no refund issued for baggage and this process took 2 and a half hours--remember, we were at the front. There was rudeness to many upset or frustrated passengers from the staff that seemed unwilling to assist people to the best of their abilities. More so seeming more agitated than the sleepless passengers. NEVER save a little money by taking this airline!! There are many reasons this airline has 1 star ratings!!!"

Pros: "The flight was cancelled dye to "unexpected weather iin Colorado" however after talking to a different airline and also a friend who flew to CO, I know it was bullshit. The weather in CO was perfect an my flight was canceled because Spirit airlines couldnt fill the flight. That is NOT MY PROBLEM and I shouldn't suffer for this. I do a lot of travel and have NEVER has a canceled flight. I used to fly between PHX and LA frequently and have been on next to empty flights but I have never been held responsible for the airlines inability to get business. I will NEVER book a flight through Spirit EVER again!!"

I will NEVER book a flight through Spirit EVER again!!"

Cons: "Charging $35 to carry a bag into a plane. Seriously. No customer service, no anything. I've gone on cheap flights before, these guys stripped waaay too much out."

Pros: "Nothing. Flight was cancelled. That was just the beginning of a travel nightmare. I can't believe Kayak compromises their reputation by representing a shoddy, sham of a business like Spirit."
Cons: "Cancelled flight at the very last minute because of lack of crew. Not enough staff to accommodate travellers trying to rebook flights. Inept and apathetic staff who were obviously resigned to the fact that Spirit is a substandard airline There was miscommunication and lack of communication in organizing travelers which caused multiple altercations between upset travelers. It was a very disturbing experience. My rebooking took an hour because the staff member didn't know how to rebook! The 'Supervisor' who was at the next desk, was SLOWLY checking bags for other customers and did not help AT ALL. I suggested that he switch places with my agent. He ignored me competely. Attempts to call Spirit resulted in multiple auto transfers and ultimately an intentional auto cut off. I was rebooked on United. When I checked in at their desk, they told me that all the other transferred Spirit customers before me had been sent back to the Spirit Desk because their transfers had not gone through. I have been warned about Spirit. Now I would warn anyone considering Spirit. If it goes right, you're ok. If not, get ready for a travel nightmare. No one needs this kind of abuse."

Cons: "I don't fly Spirit that much but what I saw looked good, on time at both stops and I especially liked getting on board early as opposed to waiting until 15 minutes before the plane takes off. What I didn't care for, but what I now understand is all the extra specific charges they continue to bombard you with are really charges you don't need. Bottom line for me is that I think I spent more money because I purchased other things and the final price that I paid was MORE then my the conventional favored airline! I will fly Spirit in the future."

Pros: "Smooth flight from check-in to landing. Young man in front of us missed his flight due to problems printing boarding pass - two agents collaborated on rebooking him. That was nice to see."
Cons: "Back of seats which were not fabric seemed finger printed and greasy. Little girl had her face up to the seat and was gnawing on it - seemed unsanitary. Maybe a more viable solution would have been for the parents to be aware of the situation."

Pros: "Cheap fares but then lost all my money because they weren't helpful."
Cons: "Security took too long and spirit doesn't have mobile boarding passes so I missed my flight. Then after I ran to the spirit counter they didn't offer my a voucher for another flight nor a refund. They said they could move my flight to the next day or do nothing. I fly a lot and have never ran into this problem before. Don't bother trying to call their "customer service" phone number either because it's the wrong number, then you will be redirected to an answering service that doesn't work, then placed on hold for 20+ minutes, followed up by a service rep who isn't helpful and doesn give you any answers."

Pros: "The flight was smooth and quick"
Cons: "Nothing bad to say about the flight"

Pros: "Nothing"
Cons: "Everything"

Cons: "What are you saying about entertainment, there was nothing!!! Used to get a little pillow, blanket or watch a movie but nothing now!! Our 1 piece of luggage only weighed 22 pounds but had to pay $104.00 for round trip for it!!! Too much!!!!"
