Food could be better it was okay. Entertainment seems dated it was something but in this day and age could be a lot better.

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.

2nd major delay due to maintenance issues. 1st delay missed my connecting flight.

The aircraft was massive (A-380) and became crowded with 400+ passengers on board.

The plane hasnt left im stuck in seatle still my flight has been grounded for almost 5 hours

My luggage didn’t arrive with my flight. Flight was delayed by nearly 2 hours while we sat on the plane and I almost missed my connecting flight and subsequently missed the last train from the airport so it took me another 2 hours to get to my destination after arriving, Crew skipped me several times when offering beverages, and I couldn’t get their attention at times because they wouldn’t even make eye contact with me. They didn’t give me a form for disembarking so I had to go to the back of the line after waiting an eternity for immigration. Paid for on flight wi- fi that didn’t work for most of the flight.

Love flying Asiana. Been using it for over a decade now.

I had a bad experience coming from America to Thailand. On my connecting flight my check in suitcase was not put on the departing aircraft, I received my suitcase 24 hours after arriving in Bangkok and when I open my luggage my hand swelled up. The next morning when I put on an outfit from my suitcase my face swelled up and became numb. My entire vacation was ruined it seems that some kind of chemical was sprayed into suitcase and ruined my clothes and got me sick. The staff at my hotel called the airline and spoke to someone and they told me to file a complaint and gave my a website to do so. I did not file a complaint I felt like it would have fell on death ears. I had to throw away my brand new vacation clothes and suitcase and I had the worst vacation ever due to this happening to me.
