Overall, very uneventful and pleasant experience. Most importantly, no delays.

Not very comfortable seated in the back plane due to turbulence

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

Korean Air had great service and the Bibimbap dish was the best airplane food I’ve ever had. It was a long flight so in between the two meals they served customers could get Shin ramen. The flight attendants let my children use a pair of nice headphones for the flight and had earbuds and slippers for all the adults. The flight was long but the time passed by relatively quickly because they have many great shows in their entertainment TV. I watched the BTS Love Yourself and Speak Yourself concerts 💜

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

lunch was good; breakfast was kinda meh cabin temprature was way too high new entertainment system but somewhat limited content

I flew Asiana Air not Korean Air which was my original flight. So, I have no say about Korean Airlines right now. I hope you guys will not make any changes of my flight on Feb 15th. I want to fly Korean Air on Feb 15th. and make sure it is the same flightr njumber for my husband also and do not make any changes on either flights. thank you for reading my letter.

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.

The comfort is typical of what I would expect from main cabin. I've been on flights with other airlines where the seats needed to be changed, the cushions were non-existent. So happy this was not the case. I enjoyed the movie selection. Happy pillow and blanket was provided since I forgot my own. The food was also ok. Great that we arrived early and my luggage arrived undamaged. Again in the past (not with Delta), luggage was lost or broken.

Crew went over and above to be helpful. Plane had mechanical problems that caused us to depart late.

The 676 plane is much more comfortable in business class than the A330 and he food was a little better. I didn’t use the entertainment.

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.
