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

The flight crews were extremely professional, helpful, and courteous. Departure and arrival times were accurate. No delay. I will use K airline again. Thanks

We were seated at the back and that was very uncomfortable for me with the turbulence we experienced on our way to Chicago.

I enjoyed flying on Korean Air. The service was great and the food was yummy. They served white fish.

I enjoyed flying on Korean Air. The service was great and the food was yummy, especially the bibimbap and cold spicy noodles. The only thing that bummed me out on this red-eye flight was that my seat did not properly recline so I was not able to sleep.

On time and flight crew are always so happy to help and always smiling unlike other airlines.

Great crew, decent food Charging plugs were broken on both seats next to me. Only the USB port was available, and that charges, very, very slowly. Seat was also broken, it would not lock into position when reclining.

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 💜

Stewardess are nice. Food could have been better and should have a better dessert. They do not offer scotch or beer. You have to ask for it. I also was not happy that you do not serve ginger ale and or cranberry juice. This is my first time that an international flight do not have this. I go home overseas every year and when I travel through ANA, Delta, Qatar, JAL, Asiana Air, United Air. they all serve this two very famous drink. You do not have a great snack tray.

You did not put me on a Korean Air flight! so I do not have nothing to say
