I wish they had movie screens in the headrests. The seats are much improved, more legroom and recently renovated. Bathroom was clean. Staff was outstanding!!

I wish they had movie screens in the headrests. The seats are much improved, more legroom and recently renovated. Bathroom was clean. Staff was outstanding!!

As always, the entire Southwest experience was wonderful, from online booking to flight to baggage retrieval. Very grateful.

The weather could have been better. There was a 40 minute ATC delay in SFO because of marine fog and a micro cell storm delayed landing and take-off at Nashville. The gate was changed 5 minutes from boarding from gate B3 to gate C23 at Nashville airport.

After being assaulted by a flight attendant I was then brushed off as oh well because he long braids didn’t mean to whip me in the eye. I have filed complaints and will see. But like any other issue I’ve had with kayak involved it’s been trash. Last time I’ll be using your app

AC sub par. WiFi not working correctly. Ac sucked. Seats very narrow.

Near 4 hour flight with only 1 service. Had to use call button to request water. Internet and power not working until into flight. Internet would stop working during flight.

Southwest's seats are the least comfortable I have ever sat in.

The cabin was quiet for the redeye flight. The area was clean. The staff was great. The 787 Max was in good condition. Drawbacks were that the seat widths were tight for some passengers. The seat padding was at best average and for a long flight uncomfortable.

Southwest like most American domestic airlines, is a mediocre airline. But it is among the cheapest. Oh well.

My flight was delayed 50 minutes and we were rushed to board to then sit for 15 minutes until the pilot arrived. Unacceptable since we could have waited to board. Also the delayed flight was updated AFTER we boarded to more than the 10 minutes as originally stated.

Perfect flight both ways. On time, courteous staff, plane comfortable and cool. Best domestic flights I’ve had in awhile.

Really low quality food especially for an international flight. The crew also was surprisingly unpleasant except couple of ladies. I know we were not in first class but that’s no reason to treat customers as less.

Flight delayed for two and half hours and then canceled altogether due to mechanical issues. No mechanic onsite to fix so had to send one from LAX.

Crew was good. The reservation got mixed up and they didn't have my TSA number. I am also a Silver Medallion and wasn't able to use Sky Priority.

Delta made it easy, comfortable and timely. The crew was fantastic.

This route with Delta always has delays or is cancelled. Aircrafts seem smaller and older. I fly Delta quite a bit - haven’t had issues with the international flights. But this route has always been the troublesome one

Three seats in first class were broken and while they were able to still acommodate us it was looking very touch and go and they had others they could not acommodate

Mechanic delay in addition to a 2 hour change in takeoff time was frustrating.

Delayed due to thunderstorms and no in-flight service due to rough weather — both of which are out of Delta’s control. Flight was good overall.

The flight attendants in SLC were rude. I arrived 40 minutes early to gate. Ticket said I needed check in for seat assignments and tried check in and attendants said they weren’t doing it. And proceeded to never call me to give me a ticket so when time to board I received the very last seat. Please relay to employees to do their job better..,

Impressed with the service despite turbulence because of the weather. Both flights arrived before their scheduled times.

Great experience…left a bit behind schedule but made up fir that in the air and landed 10 minutes early 😁

Electric plugs didn't work. Entertainment system wasn't working

The design of the light switch on the arm rest is ridiculous.

The gate attendant let me walk right by her with a bag too big for the overhead compartment

Overall, it was a good experience. Boarding was good and there was plenty of overhead bin space for everyone’s carryons (even when we boarded toward the end). Only improvement would be to offer trash service more regularly.

David went above and beyond to make our flight the best that it could be

No food service almost missed because of first flight delays

Had a hard time finding my assigned seat. No attendants to assist.

The negative was the wait at the airport coming back. I checked my bags in, an hour before boarding and I get the notification that my flight was delayed. Rather had gotten the notification while I was at the hotel. Then it was delayed 3 x’s. Ugh!

Given it’s a red-eye into Charolotte, we didn’t get any food. The survey does not include “N/A” so the rating will be skewed.

Great. Quick and quiet and east. The breakfast choices were a welcome surprise!

American airlines suck they delay the flights all the time made me sleep in an airport because my flight was delayed and I miss my connecting flight

There's nothing I liked about it. For first off I scheduled this trip two weeks in advance then they delayed my flight which messed up my whole trip. So I scheduled it for the following weekend thinking there won't be a delay and guess what as soon as I got to the airport we said in the airplane on the tarmac for an hour and a half. Not only was it delayed I missed my connecting flight meaning I had to stay the night at Dallas-Fort Worth airport sleeping on the floor. I will tell you this I will never fly American airlines ever again I have had nothing but horrible experience with them and I just throw money at them

The stewardess hit me with the food kart twice on the head and didn't say I'm sorry once. The same stewardess gave me a warm Apple Juice with No ice. The Flight was delayed for Departure 6 times, starting from 2:36pm, finally taking off 7:50pm. I was late picking up my child from the sitter by 3 hours.

Don’t know they cancelled the flight day before I was to leave. They sent a email at 9:00 pm at night saying they cancelled. That is the smooth way to say we don’t want your business! I think they didn’t have enough people booking so they cancelled the flight! It’s all about the money anymore there is no honesty in business.

Having to reschedule flights a day later, they loaded by luggage on the wrong plane from Little rock now I have to HOPE they deliver it to where im staying like they said would. International flight crew was very disgruntled and not very friendly.

We will be writing a long, detailed letter to corporate about our awful experience with American airlines.

It took way too long to diagnose and solve the problem of a broken crew member cabin seat. Though compensation for the volunteer who left the flight was very kind.

The entertainment package was vast and the selections were very current. Keep updating it was great.

very difficult boarding process - aggressive passengers not the friendliest crew

WiFi was not eorkig (again) And the plane was from 1990 with the screens which were.not touch and most didn’t even work and if lucky could tune in tv

I paid extra for a seat closer to the front. The TV didn’t work at all for the entire flight. Would have been nice to know before I purchased an “upgraded “ seat

It was great. I had never flown on JetBlue before, but would be very happy to fly with them in the future.

Worst flight experience ever flights canceled. JetBlue told us just did not even bother standing in line to come back in one and a half hours then without any information we had to go pick up all of our luggage and spend over $2000 in accommodation just to get home. JetBlue said that the next flight available for us to get home would be three days later. Absolutely absurd hasn’t offered to give us any compensation do not fly JetBlue horrible company. They said it was based on the weather and the weather is great in all locations that we would’ve been flying to total hoax. I think it’s a conspiracy theory.

The captain gave good announcements and the flight attendants were friendly. The WiFi was pretty good. The plane itself looked very old inside and the seats were very uncomfortable. The screens in the seat backs were the smallest I’ve ever seen. There were so many loud and obnoxious kids on this flight and the parents didn’t do much to try to quiet them down. Some had videos and games on tablets with higher than necessary volume going the whole time.

Too many long delays with JetBlue. Worst major airline that serves JFK but unfortunately I keep going back because of the prices.

My JetBlue experience was nice. The flights ran on time, the aircraft was clean and comfortable, and the flight attendants were attentive. My only issue, which is isolated to the low-cost (budget) option at JetBlue, is that the check in process makes the user feel that they have to buy their seats. The seats offered for purchase are upgrades from the budget seats you get (which are essentially the last seats remaining). The interface should not make it feel like you must purchase a seat.

The plane was late to leave.. Internet was lousy. TV was not working. when we arrived, We stayed on the plane for a long time before we got to the gate. It took us a long time to retrieve our luggage because they didn’t know what carousel to send them to. It was a bad experience.

I especially liked the lead crew officer. His boarding and safety announcements were made with a bit of novelty and humor. The flight also left the gate 10 minutes early and we landed about 20 minutes early… It was a delightful flight…
