Waited a long time at JFK to board with no information being readily available.Left about 45 minutes late and it was 2:45 AM in JFK.Nothing todo. Second deck of the Airbus is more comfortable or seems that way because there is less people. Food was OK. The food on secondleg was better as we had ordered it before hand. We thought we had did that on the long first leg but we were told we did not. Cabin crew was generally nice. There are people who lean back when eating as they wait for food to be delivered and know no one will check -- drag. TV selection was awful movies OK. Comfortable all in all.

Not enough seat cushion. Butt was hurting especially on long flight. Not enough movie selection. Entertainment was outdated. Coffee served was cold. Other than that flight was good.

Humm, I should have known that the seat I peaked on my flight from Inchon to Manila was designed for a toddler or very small person.

The staff hold my luggage to steel and exchange my stub, i was very disappointed.

Kayak along with airfare assay are attempting to steal my money. Charges are being pressed.

Customer service and attention to details. The food was good.

I’d have rated Asiana good except an unfortunate incident in which I felt one of your employee didn’t really help us. During the first leg of the trip, the flight from LAX to ICN, I left my backpack on the plane. When I realized, I reported to one of your employee who promised me that it’d be taken care of, that my backpack will be there at HCM city. When we arrived there, HCM people had no idea and my backpack was still at Incheon airport who denied any knowledge whatsoever. I was left in the cold and felt helpless. I was very disappointed. I’d like someone to look into this and let me know.

It was my first time flying Asiana but i was very pleased with how professional and understanding the flight crew is with little kids. One flight attendant held my 3 year old daughter’s hand guiding her to the exit after landing while i had my hands full with luggage and my infant. She was very helpful.

Better screens, it would have been nice to have more comfortable seats.

I’m glad to comeback after 7 years. Flight from LAX-ICN was excellent
