Crew and cabin were very good. Movies were mostly old or very old (wizard of oz, gone with the wind). Knee room is a bit short, but not horrible.

Crew and cabin were very good. Movies were mostly old or very old (wizard of oz, gone with the wind). Knee room is a bit short, but not horrible.

It was great. I had an exit row seat so I had a ton of legroom. The service was good and the food was decent.

Aircraft used was a 10 year old 767 which is being maintained in excellent condition. Business class was very comfortable and reclined sufficiently to allow me to sleep. The crew were excellent and very attentive. The only two unfortunates were a) food quality, the beef was very tough and below the standard for business class service; and b) the onboard entertainment offered little for non-Mongolians. All around, I would gladly fly MIAT again.

The flight was on time and the aircraft new and well-maintained. Service was friendly and well carried out. Seating on the 737 MAX in business class was comfortable enough that I could doze off during the 4 hour flight. Arrival in Ulsan Baatar was on time and baggage delivered to the belt quickly. I was pleasantly surprised by the entire event and have no trouble recommending MIAT.

No entertainment display working whole flight it was like a veggie 😒

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.

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

The beefsteak on the lunch menu was excellent! I usually do not eat airplane food. I loved it.

For the most part, it was an enjoyable experience. It's the 2nd half of the journey was a bit uncomfortable. It was on a noticable smaller plane compared to the previous one.

Only process that my luggage didn’t make it to my destination because of short connection but I understand

I like the food, the crew and everything.!!! Except for the delay in our flight.

Check in agent very rude, no greeting “Hi” or “ Thank you. Doesn’t direct where to go for gate info. In flight crew staff not friendly. Very disappointed ☹️

My favorite airline to fly across the Pacific. The Business class lounge is fantastic, the wonderful flight attendants are helpful and professional. Great comfort while flying.

The flight was delayed for 2 hours, however, we flew home safely.
