Friendly flight attendants. Comfort plus seats were very comfortable and had lots of leg room. 10A and 10 B.

I've flown many many times on Northwest and then Delta. The crew on this flight were absolutely the best I've had the pleasure of being looked after by.

Flew first class so everything was great. But maybe because the flights were red eye, no meals were served, just chips. I flew Alaska Air 1st class at 9PM (2 hour flight) and they served beef short rib sliders!

Had to change aircraft due to a faulty door. Surprisingly it only caused about an hour and a half of delay. Delta handled this situation as well as can be expected.

Awful. Flight was continuously getting delayed and gates kept changing without any reason. Flight was delayed for more then 3 hours

Paid premium for Delta only to be on safe but tired old 767 with ancient cabin in mediocre condition. Poor wifi and horrible inflight entertainment. Hardly a premium experience. Should have flown SW and had fun flight crew and no pretense

Our flight to Zurich was delayed by almost 3 hours, so we missed our next flight. There was no indication it would be delayed this much. We were told the gate had changed and then it apparently took over 2 hours to load the "catering" on the plane. We were not compensated in any way for the trouble.

Rated entertainment as Mediocre as there were major problems with the Infotainment system that took probably a half hour for them to fix.

Your crew could maybe answer the call bell at least one of the times I pressed it. I pressed it first time with 2.5 hours left in our flight bc my partner was hungry and wanted a sandwich. We finally got the sandwich with 40 mins left in the flight.

Half the bathrooms assigned to economy were out of action

Besides the flight cancellation, everything else was prefect. Kudos to Malaysian Airlines.

Operated by American Airlines. Very chaotic and the crew was bit rough responding any enquiries. Restricted leg space.. Qatar would have been better

Qatar airways from Doha to guangzhau was excellent big bird Boeing 777 more room and smoothly flight, I Love it

It was good no problems made it on time for the next flight overseas!

The made us waiting and held our passports and boarding pass making us miss our flights

Not impressed. Only allowed one carry on on such a long flight.

The flight was good but my neighbor had the vent open full power for the whole flight and because the air was blowing from the side instead of from the top and I got very cold and ended up with a sore throat.

Bad experience with the delay n long wait time for connecting flight after missing the connection flight from Doha.

Wore experience due to delay and took me 3 days to reach my destination.

All over with Qatar airlines my experience was really bad due to delays and then putting me on different airlines and after 8 hours of wait I had to listen to their is no plane to fly for another 24 hours. Wore experience ever.

Overall fine but both ways for this trip was delayed.

Flight was delayed by almost 5 hours. Suitcase was not loaded despite the flight being near empty (my colleagues’ suitcases did reach JFK, unlike mine). Had to argue on phone to get JetBlue to deliver the case to my hotel. Never again

The flight was excellent. The crew was welcoming and attentive.

Great! I love Jet Blue. My favorite airline! Very efficient, clean and timely.

Run out of snack choices. Why are the seats not padded for your butt? Are we sitting on blocks of wood or metal for $250-300 a pop? This ain’t spirit. Let’s get it together people

We were told that our flight would be delayed for 90+ minutes because of weather, so we went to get something to eat only to have them randomly start boarding 15 minutes after the announcement, with no warning.

Entertainment... No earphones passed out. Many including me couldn't use the TV. Legroom was good. Crew was indifferent and a bit surly. Free wifi was a nice convenience. Check in desk location was unknown. Gate number on the boarding passes was wrong.

Going through JFK’s security is a mess. The TSA security said no shoes on the bins. So, we place our shoes in the belt and they came out all over the belt. Boarding was delayed and Flight as well.

Safe and on time were the positives. The plane wasn't cleaned before boarding, there was garbage and food on the floor and in the seat pocket. The TV screen was small and the picture fuzzy, audio quality was poor. Seatbelt was fraying and seat did not recline properly. No charging ports near the seats,

Confusing. Delay updates were out of whack At one point it said my flight was 25 hours. Three gate changes and two delays only to change back to original departure time. Gate announcer and on board flight attendant (Alejandro) making the announcements was impossible to understand due to accent and speed of speech. After beverage service the rear flight attendants sat back there on their phones. No refills no checking in, one sweep through for trash collection. Very impersonal. Bring back Coke products

Overnight flight in the old style Business class, but still very good.

I was in business class, without the business class amenities. Large seat with lots of legroom, but no TV or bed. Food was okay, but I did enjoy the Turkish red wine.

Excellent service and comfort from the moment you check in. Flight crew is hyper focused on making passengers comfortable and at ease. It’s like a flying hotel!

Only chicken as a meat dish through out the flight

Nothing really was great as such. Seen other no name airlines perform better.

Quality of service on board was very inconsistent. FA service primarily seemed robotic and they barely engaged with passengers

I’m unclear why I had to pay extra for assigned seats as Turkish airlines did not honor the seating. We were placed across the aisle from each other on TK 34, and were seated behind one another on TK 694. Because my name was misspelled on e-ticket (Klawiter, instead of Klawitter) I could not log onto website to get the connection gate number in Istanbul. The monitors in the airport were a jumbled mess 1/2 Arabic and 1/2 English.

On line check in needs a lot of improvement. I tried and gave up.

Food not good, flight attendants not the best, not accommodating very ruff

the female flight attendant was racist towards me. I could tell she treated the two other passengers next to me with more softness.

AA1537 the AC was not working properly. It was very hot and uncomfortable.

Overall the flights pretty good. The snacks we’re good and they were plenty of them. Both boarding and deplaning went quickly.

Delayed abs delayed Gate crew giving poor info - we are definitely leaving at —- Ultimately to cancel flight after 4+ hours of delays Just cancel it earlier

The flight was scheduled to depart DCA at 12:30 pm but was delayed twice on the ground so that we were finally scheduled to depart at around 4:00 pm. Once we boarded, it was announced that takeoff would be delayed again to fix a hydraulic problem which delayed our eventual takeoff until around 5:00 pm. Once we departed, it was a smooth flight back to ORD. We did not get any explanation about what caused the original significant delay. In my experience, this happens frequently with AA.

Lots of weather delays that were poorly communicated and managed. I get there are weather delays but they didn’t make it clear what was happening or comfortable on the plane

Everything was on time; the flight attendants and the gate personnel were very pleasant and helpful.

Our second leg to Jackson WY was unable to land due to weather. We were flown back to Dallas after stopping in SLC. We were given hotel rooms and vouchers. We were told that we would be back on the same plane in the morning. Instead we were given a different flight with different seats. Not a good experience. No one knew what was going on.

Perfect flight. On time departure and early arrival. Smooth flight.

Awful! The flight was delayed and we sat on the plane in DCA for an hour because fuel was out in the wrong part of the plane and would not be accessible during flight. So the plane had to be refueled in correct tank. They also allowed someone to get off of the plane. This delayed my six hour flight by an hour and made me miss my connecting flight. I ran to new gate and American Airlines agents new about the delay and even knew that I was trying to make the connection. They knew thru communication with my friend while in flight that I was in the airport and running to the new gate and they still closed the gate and refused to let me on the new flight despite plane still being at the gate. It was horrible and I had to be rebooked on a flight for 24 hours later. This has been a nightmare and if American Airlines can cause customers to be delayed and then have zero empathy as having an on time flight was more important to them than helping a customer who was delayed by no fault of her own, then it's seems that it's not a company that I want to continue to give my loyalty to. I'm so disgusted.

Help was available but timing was bad in my case
