It was amazing. I was not expecting the phenomenal customer service Asiana provides.

It was all perfect and very pleasant for such long flights

The seats felt very small. We were supplied with pillows and blankets, which was nice. Lots of noise from the bathroom, plus exterior noise. Made it hard to hear the entertainment system, even using my own noise-cancelling headphones. The food was really bad. I generally request a vegetarian meal and one was supplied, but the pasta was cold and hard and there was nothing pleasant about it. Two meals were served on this flight; one was a repeat of the meal I had had on the flight immediately preceding this one, which was bad enough I didn't even try it. Drinks were very limited. All I wanted was water, and on a 10.5 hour flight, I was given 3 cups of about 3 ounces each.

We took business class, It was comfortable and I was able to sleep.

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

This has been the worst experience I've ever had. We arrived to Ho Chi Minh Airport and were supposed to get our Asiana ticket from the transfer counter as we came with a different airline. However, the staff at the transfer counter were not helpful and kept giving us different information. We were first told by Asiana airlines staff we had to wait 2 hours so they could print out and give us our tickets, then someone else told us we had to wait 3hrs, someone told us "I don't know, just go sit and wait and we will tell you later." This was at a place in the Ho Chi Minh airport that had no coffee or food shops, nothing, just immigration (to enter Vietnam with a Vietnam Visa) and security (to transfer into the gates) but we needed our printed boarding pass to go through. It wasn't until we demanded to speak to a supervisor as our flight time was 1hr away because they kept telling us "there's alot of time left for your international flight, we will get your tickets later" we still had to wait around 20minutes for the "Supervisor" to give us our tickets. I would NOT recommend Asiana Airlines, especially if going thru Ho Chi Minh Airport as they are not helpful. (We almost missed our flight, due to their lazyness and incompetence of printing our tickets) I would suggest Asiana Airlines to have a Machine in the transfer area so passengers can easily print out their boarding passes themselves and save some money by not hiring incompetent staff that can't do a simple task such as printing a boarding pass.

Great service. They could offer vegetarian food and do more to reduce waste.

Great service and comfortable seats. The first meal was excellent but the second meal was only satisfactory

The staffs are very accomodating!!! The foods are good!!! The entertainment from manila to incheon was miserable because we need to use our own cellphones or own ipads.

At the boarding gate, Jeju airline accepted "carry on" bags for checking in for free due to the "limited cabin space". This is because most passengers were carrying multiple bags that exceed the size and weight limit for carry on items. Rather than inspecting carry-on bags at the counter and requiring excess bags to be checked in for a fee, they allowed freeloading at the boarding gate to to the detriment of those who paid the fee for checked bags. This is totally unfair.

As posred earlier the crew was very accommodating & professional. Thank You Allen

All though you can not help it the kids was loud and unruly, The crew was very accommodating and professional. Thank You Allen.

No priority counter check in for families with young children.

The flight was delayed from GUM to ICN, there was no notification on how delayed the flight would be. Although we received notice, there was no specified time given. The flight was also very uncomfortable.

Cons: "Sold me a ticket then cancelled 15 minutes later due to not having updated information from the airline on bookings."

Quite ordinary, as might be expected of a budget flight. It was difficult to understand the instructions unless one speaks Japanese, and the seats were quite basic.

Very easy process overall. The staff communicated well and everything was efficient.

Very affordable, smooth check in process, flight attendants were safe and kind, lots of flight availability within Japan.

The seat is so bad Can’t recline the chair

For Travelers with babies, if they can be supported by allowing to carry the Baby stroller upto the Airplane gate, and not submit at the Check-In counter. it will be very convenient. Thankyou.

I didn’t even fly on it can I get my refund
