I won't hesitate to fly with Korean Air again and agian....if I can get a good deal.

The flight attendants seemed to be a little more grumpy this time. A350s could use more toilet stalls.

It was horrible. The flight crew was unfriendly and the food was absolutely horrible.

Absolutely horrible. The fight member crew or not very friendly and the food was horrible.

It would be better if flight crew can clearly communicate in english. But they are kind and accommodating. Food is good, especially the sandwiches on the self-serving snack trays. They are better than the ones served. Boarding was organized.

So far one of the good one , whenever I go to Korea , I always use Korean airline .

They could have had more up to date movies/better choice of music.

Will try never to fly Delta international again. Flight delayed and staff completely inept in dealing with it. Would not communicate, rude, completely disorganized. Once we reached Seoul the staff there had no idea what to do with us and led us around the airport from one pointless line to another. They were clearly not told how to manage the situation even though they had hours to make a plan. Never again.

They texted me my gate number and then they texted me again it’s now boarding but in different gate, and the gate was so far from the gate they texted me earlier. I have to run just to get to my flight. They always do that.

The crew and my luggage was still pretty good after a long flight. They take good care of the luggage.
