The flight crews were extremely professional helpful and courteous. Departure and arrival times were accurate. No delay. Thanks

Not very comfortable seated in the back plane due to turbulence

Everything about Korean air is great, hands down! Will always prefer this airline from other carriers.

Ford not that great the seat not to big for leg room like other airline

Crew was ok, but some passengers were a bit rude. Again, all outlets were not working, only the really slow charging usb plug on the entertainment system. Entertainment system was also bugged, some features just crash, the touch screen wasn't working and when trying to watch a movie the onscreen display kept flashing off and on making it very difficult to watch.

New plane. Perfect gluten free meal Very flawless procedures from check-in to the landing. Taking off on time and landing even earlier and the luggages are already there after shortest arrival report.

It was ok. Not good and not a bad experience

not too bad but not too great either. Service on all airlines declined ever since covid. Your Delta Stewardess are not that friendly at all. :-(

I like your stewardess, they are nice. However, your food could have been better and wheres your dessert? You do not offer beer or scotch. I do not drink alcohol biut my husband can have one or two, he has to ask if he can have one. during dinner or lunch, it should be offerred. Also, you do not have the most famous drinks ginger ale

Not accommodating ground staff On board slow service Crew members not very friendly

Comfort of seats, ease of boarding. Food selection could be better

I arrived to the airport 2 hours before my American Airlines flight was scheduled to take off. I have TSA pre-check. The airport was crazy packed when I arrived. After momentarily standing in the pre-check line, the TSA agent said that I am not pre-check. Of course I said that I am because I entered my KTN number on all my traveling sites and programs. I had to get out of line and go back to the AA counter to discover that American Airlines did not add my KTN to my boarding pass. I had to call TSA to find out my number, then have AA enter it onto my boarding pass. The emblem would not load onto my boarding pass. By this time, I decided to use my Clear in order to get through TSA but the line was ridiculous long. By the time I made through TSA, I missed my 11:08am flight and was re-booked for the 5:30pm. This is after the AA employee told me I should have gotten to the airport early. AA use to be a dependable airline not I use them only if I have too.

Horrible people at the gate, they force me to check in my carry on, even thought no one behind me has to do it. I had to get out of the airport in NY to get my bag and go thru security again on my way to Honk Kong. The worst part is the employee threatened me with loosing the flights if don’t comply.

Transfer from Terminal 1 to Terminal 3 by bus is chaotic, because as per information Free Shuttle Bus was supposed to take passengers from Domestic Terminal 1 to International Terminal 3, but the bus took us from Terminal 1 to terminal 2, then to Terminal 1 ,, 2 and finally to Terminal 3

The flight crew was really wonderful, incredibly helpful as well as patient. I was able to watch entertainment on my phone but didn't have access to my headphones and I didn't want to bother the flight attendants. The food wasn't an issue for me because I am a vegan and brought my own food on board. The flight left on time and arrived ahead of schedule. It was overall a good flight.

Cut off carry ons, had to check, got on and there was plenty of bin space. Disappointing.

One of the worst flights I have ever taken Delayed over an hour without communication from the crew; very scary Entertainment not working Crew NASTY cabin cold

May never fly American again Delay in take off WITHOUT EXPLANATION Cabin freezing Crew NASTY entertainment did not work entire flight

Crew was rude and the flight is not comfortable for long haul.

The flight was so short that the lack of leg room didn't bother me for long. The plane was smaller so only two seats per row and there were chargers. However, they didn't serve any snacks.
