The price of the tickets isn't matching the flight experience. No matter how long the flight is, you're only getting pretzels. The flight attendants looked unkept and over it.

The price of the tickets isn't matching the flight experience. No matter how long the flight is, you're only getting pretzels. The flight attendants looked unkept and over it.

WiFi on the flight was not working. Thus, entertainment options were limited.

Flight was awfully bumpy and landing was a bit jolting. I was in the restroom when snacks and drinks were served and was not asked if i wanted any. I had to ask for water finally.

Multiple delays and gate changes. Arrived at final destination 6 hours late. All rental cars had been taken.

Crew was great flight was great baggage claim was a failure. It took over 1 hour for bags to arrive. Poor communication poor effort when I spoke to the supervisor about the delay

The movies using Southwest WiFi kept pausing and I had to restart multiple times.

First, my flight was a usual flight nothing exceptional or unexpected. Over all it was a normal, good flight! Second, your questionaire is wholly lacking in the proper options to which one can answer a question. Often on short flights, there is no food let alone entertainment so why isn't that reflected in your questionaire? A simple "not applicable" would cover that issue appropriately but no, your form arbitrarily enters an answer based on the initial assessment which normally isn't factual. Until you provide an accurate means of assessing flights, I'll no longer be completing of these unimpressive and misleading assessements. Thank you!

Planes are aged. The wifi is unreliable and on many fights, no-existent. The flight attendants were very good.

I had a wonderful flight, but the only thing that annoyed me was how crowded TSA was. I still believe airports and all planes work together to bunch everyone together to drive up cost.

Easy to book and to get check in and get on and off.

The plane pushed back from the gate on time. However, it stopped on the ramp, and we waited for over 20 minutes before the aircraft pulled back to the gate. Apparently, something of importance had to be removed from the aircraft by the gate agent. I found this to be odd. The delay was not significant, but I felt that whatever was on the aircraft that had to be taken off, should’ve been done before we pushed back from the gate.

Smooth boarding process. Early departure, smooth flight, early arrival. The entertainment package has very good recent movie options. The flight crew were friendly and professional.

My suitcase was destroyed. The top part where the handle is is completed broken. And unusable now.

Since when do I have to pay for my checked bag? I have a United Explorer mileage plus silver card and I was charged for my checked bags. This also is an international flight. So I would like an explanation to be clear before I choose an airline please?

Michael, our FA was very attentive, even finding me a chocolate brownie from economy class when the dessert selections were all dairy based. ( intolerant, not allergic so don’t usually need to order dairy free)

I had a bad experience with the security at IAH and felt like a sardine on all 4 legs of my journey.

I don’t understand the purpose of the orange “priority” tag on my bag. This tagged, my bag is last or near to the last bag to come down the carousel at IAH.

Oh my gosh, I loved my experience with United! they made me want to travel more often.

The planes are so dirty! Food crumbs and finger print smudges, Dust over the vents and carpet stains. It’s disgusting.

The bag drop personal were not helpful. There was no food on the flight. Boeing aircraft, lousy as always. Everything else was fine.

Several delays. Next flight was worse. Did not arrive home until 2am PT

The flight to Tokyo AA61 took off about two hours late, but then had to turn back. By that time the crew had to be replaced. Then they kept promising to take off in an hour, then in 3, then switch to the next day.

Any sort of gluten free snack option would be nice

I had a carry on and a personal bag. I put my personal item under my seat and on way to the seat I put my bag up. I usually close my eyes and rest as I was on call for last 36 hours. I heard very loud announcements that someone needs to identify their bag. Pretty sure it was not mine until the hostess pointed out my jacket details attached to the bag. I asked why she got my bag out. I got berated and did not want to create a scene. But this person needs to be talked to.

Between Las Vegas and Dallas was okay But, once in the Dallas airport, notice, I have disability and ask for a wheelchair, they leave in a middle of nowhere, the personal in charge try to push me on a cart where I couldn't sit because was to high. Then they don't care about me, they bulling, till I start to yelling and crying, ask to everyone around, who can help me. The man in charge make a despective movements and said you are to loosing the fly. The last name in his batch started with an H, I did not have the full name. A nightmare. After all, a woman in charge was walking very slowly and asking me for a tip cause she was helping me to reach the fly. For years, AA has been the preferred airline. The personal in charge of the disabled people are discriminate me. Thank you Kayak.

Flight was late and missed connecting flight. They could have better accommodated, but instead did an overnight and had to arrive the next afternoon.

Awkward carry on process. Forced to check all carry on. No overhead space of worthiness. Left delayed, but made up the time. Crew was amicable.

April was the flight attendant in first class and was the most pleasant, cordial and efficient person I have seen on a flight in years. Good example of the type of people AA should hire to increase customer satisfacdtion.

Two flight changes before the scheduled flight. On the day of the flight, the flight was delayed, which caused the connecting flight to be missed. Then, I was directed to another airport (CUN) and traveled to Tulum. American gave a $12 voucher for lunch. The least expensive item on the menu at a Mexican restaurant was $9.99. Driving to Tulum was a bad auto crash, and traffic was delayed two-plus hours. The bottom line is that we should have been at the hotel at noon, but it ended up at 11:30 PM.

The boarding experience was good; $20 for wifi per flight is uncompetitive compared to Delta, Southwest, and others, and puts American lower on my list given similar pricing.

Flight was delayed a bit, but that was expected (and updated), so really not bad at all for the price. Could’ve used one less email asking me to upgrade my seat; otherwise no significant complaints

Easy boarding. Met expectations for a 2-3 hour flight. Early arrival at DFW caused a 39 minute delay on the tarmac in getting to our gate. 😏 overall, good flight.

My experience with Spirit went pretty much as expected. It's a no frills airline, and you get what you pay for. I don't require much, so I was grateful to have an inexpensive way to travel. It is sad to me that the gate agents and flight crew don't smile much or seem very friendly or helpful. They are competent and efficient, and that's really all I need.

It was fast but uncomfortable seats. Had to pay a bit extra not sure why? Maybe in selection of all my 4 tix together ? Just knew I had a balance before getting boarding pass online when departing from satx ? And flight was delayed..

Last minute 2-3 hr delay in flight schedule; no explanation Unexpected extra $52 charge What's the benefit of choosing a cheap airline if you trick people last minute and force them to pay extra last minute? Did not appreciate being cornered.

Most uncomfortable seating I have ever experienced. And they do not provide any beverage unless purchased. Water was 4.59 a bottle. Same for a soda. A cup of water should be free. I will never fly Spirit again.

Seats are uncomfortable and too close together. Also, you missed my connection in Vegas on the way back and I ended up sleeping in the airport, flying back to Burbank instead of LAX and I got home 12 hours late.

They are very particular about size of the bag. Mine is small bag and has wheels. Bag wheel edges are bit outside of the measurements bucket. They charged $99 as carryon bagage

Non-professional acting crew, Very uncomfortable seats…!! Very bad pricing with all the add-ons for seat choice, luggage fees, etc….soon you’ll charge extra for oxygen. The ticket price means Nothing because in the end, the actual amount i paid, i could have and will in the future continue to fly on a real airline…

Your employees need to learn how to talk to people as creations of Yah. We are not their children nor are we lower than them.

It was a short flight so no food or entertainment….

Seats are uncomfortable but price is good. Guess I can put up with misery for four hours.

Cancelled and declined to find alternatives Earlier flight is 2 days later Sent the cancellation notification very late, wish I knew earlier would have stayed to watch the Miami open final game Very disappointing service

They switched my flight to Spirit, Never using Kayak again,

Frontier had yet another flight cancellation. Have never made a complete round trip with this airline without at least one leg getting cancelled. Miserable flights - dirty, uncomfortable planes that apparently always have issues since I've had multiple delays and cancellations with them.

The flight itself was ok and the pilot was very communicative. However, our flight was delayed for almost 3 hours, the gate was changed 3 times and there was no communication as we were waiting. The flight staff was overall a little crabby...I understand as they probably had a long day but we all did.

Asked for a seat change to be w my wife at the gate they were great in sorting it out to make it happen

They changed the timing , first delayed by 4 hours then went back to 40 mins late, we had to run back to airport to not miss our flight. This is ridiculous

Early arrival. Great landing. Pilot updates. Too cold in plane.

They cancelled the flight and did nothing. I should be compensated for my uber rides to and from airport. Not a good service by frontier or kayak.
