If you're flying into Ho Chi Minh with a different airline, make sure you have printed tickets because security does not accept mobile tickets (only printed) and hopefully other airlines are better than Asiana otherwise, plan to spend several hours in the transfer area with nothing available other than bathrooms.

I will not fly to ICN and transfer to Hawaiian again. Both Asiana and KAL are good flights to ICN. And their lounges are both good. But if flying onward, stay with Asiana or KAL connections. ICN doesn’t do terminal connections well.

Do not take a budget airline next time. If there is no choice but Cebu Pacific, then don't pay for checked bags. Just bring a huge backpack, a carry-on suitcase, and one big handbag (personal item) up to 10 kilos each. Cebu Pacific does not care about these things anyway.

Great airline. Our bus to the terminal got delayed, but there was no problem to check in last minute. Super friendly terminal staff.

Aircraft is pretty old. Seat is not comfortable. Meal quality is disappointing. Entertainment system is not impressive at all.

Always on time and flight crew were great. Boarding in Manila was a bit chaotic and disorganized compared to Incheon.

Never had a flight delay issue with Korean Air, that's why I always go with this airline.

Flight crew were very attentive and made this trip a pleasure. Plus the fact that this our first time flying business class.

The boarding process was efficient and quick. The seats were comfortable. The food was good. The service was excellent. We had a lovely flight from Seattle on Korean air

Flight crew was fantastic. The aircraft was meticulously cleaned at all times. The crew was continuously checking to see if the passengers were ok.

Korean are so racist and when I ask question or directions they totally ignore me and say racist. Also they give me an rude attitude.

It was good, I liked the self-serve snacks but it was a little difficult to get the alcohol, which is understandable since I wouldn't want kids sneaking it.

Friendly flight attendants and gate agents. Very clean plane and food was good!

I normally love Korean Air, but this trip was not great. We boarded the plan and were settling into our seats. My son and I use these leg swings and we used it on the trip over to Cambodia, but on the way back the flight attendant very rudely told us we could not use it and that it was against regulations. I asked to see the regulation, but never saw it. The food on this trip was horrible as well, Even my son's kids meal was disgusting so we didn't eat anything on the flight. Thankfully we brought snacks. Entertainment - what happened to the games?
