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

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!

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

First time I’ve ever missed a flight and it was an international flight.. Southwest put me on the next flight and it was the best experience possible.

It seems as though the provisions are even less. Although SWA used to be an economy Airline, that isn't really the case anymore. I paid over $700. for a round trip to Denver and I could have flown just about any airline for the price. The drinks are now in a 6-ounce cup and with ice I'm sure a can would fill more than 2 cups. However, I am very proud of SWA for using paper rather than continuing to contribute to the millions of plastic cups being used each day. I've thought of this fr many years and am so glad to see it come to fruition, if not by only SWA so far.

Service was great, boarding and exiting went smoothly, and the flight was very pleasant.

Southwest is amazing. The only issues I would have to say is. I don't like the unassigned seating, and the fact that the flight is completely sold out. It makes for a very tight fit. Other than that. Crew was great fun professional and attentive.

Everything worked well. Crew was as entertaining as is possible on a plane flight. Southwest still has good legroom:

Crew was great - friendly and helpful with boarding - letting folks know where overhead space was available thus getting us out of the gate on time.

Delta is my preferred airline. I've traveled with them for years. On time in most cases, good communication, easy to use app. Most planes are pretty nice. I was on a CRJ 700/900 however, which was pretty badly aged inside and needed a refresh. No infotainment, unreliable wifi, best to download before boarding or bring a book. Food choices are really just snacks on this flight, nice variety but about what you'd expect. Great staff and prompt in departure and early arrival too. Overall quite satisfied.

Crew was friendly Love the entertainment in the seat head rest.

Delta flight was on time, seats were comfortable, and crew was nice.

This had nothing to do with Delta… The flights were on time and flawless. The service was excellent. We purchased seats in (aisle/middle) comfort plus since this was a cross country flight. Unfortunately, the woman seated at the window was 300+ pounds and, as might be expected, covered up about a third of the middle seat also. there was absolutely nothing that Delta could have done about that… I just don’t know what the answer should be. If you purchase a seat, you should should be able to use the entire seat and not just the portion that someone else is not sitting/oozing in. Disappointing…there should be something that could be done….I'm just not sure what solution could be.

Delayed take-off. Very small plane so very scary with lots of bumps during the flight. Would never fly Delta on short flights in small 80 seaters plane again! Felt relieved when landed.

The worst part was I was NOT allowed in the lounge even though I was holding a first class ticket and have a premium American Express card. I have flown Business or First Class with many airlines. Delta is the ONLY one who does not extend this courtesy to anyone except people who hold the very expensive American Express card. As a result, I won’t fly Delta if I have any other choice.

A little bumpy ride . No food was being provided due the the turbulence. That was ok it was a short flight to my standards.

Simply outstanding. Their new lounge for Delta One customers is a cut above the rest.

The Dekta Rep that checked us in was great. She's very personable, pleasant, and can tell she enjoys her job.

The plane was old with small storage areas that had problems closing/latching and not enough storage for everyone, and worn, damaged seats. Service was great but feel a little unsafe on such well used planes.

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?

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.

Asked several times dairy free options and was ignored. Was told chips was the only thing I could have that I should have put it on my profile “which it is”. Very unprofessional. WiFi didn’t work have the flight. Overall a very bad experience.

Plane still had screens for watching movies. Good selection too.

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.

Kayak never booked my flight, I have received notifications the entire time the fights were to be used I went to the airport to find out despite receiving these emails to board my flight was never booked only to have to return home and miss the event I was scheduled for, inconvenient and devastating to say the least, customer service was very poor to only explain that my card had not been charged so that I shouldn’t worry. Yea great for you to say being that your not inconvenienced.

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.

Spirit moved the departure time by 45 minutes to an unacceptably early time. I wrote multiple times canceling the reservation and received no reply or refund.

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
