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?

This was an amazing flight. The crew was great. The service was great. The food provided was great.

I was unable to select decent seats, and so I was stuck in the middle seat because it was selected for me

Very bad. They don’t allow group people to sit together by blocking most of seats and opening only single seat during online checking in. . By doing so, they can rip off customers at the check-in counter by collecting extra money if we want to sit together in the same row.

We are glad to have used China Airlines for our trip. Continue the good service! Thank you!

The flat bed full lying position is not comfortable at all, this could be improved, it is at an awkward position which i dont have the same issues with other airlines business class.

The flight was uneventful and the crew was kind and professional. Really appreciate the option to order a vegan meal for the flight!

I love my Delta crew, they were so welcoming and helpful.

Overall was a lovely experience. The crew were kind and courteous throughout the entire flight.

Sat next to a woman who had her period. Blood was on her seat and on the arm rest between us. I ended up having period blood on my jacket and shoes. Very gross!

Better organization of boarding procedures. Terrible leadership guiding people to gates.

They need to improve on how the plane lands cause it was not smooth at all.

I did not like how the plane landed. It was not smooth.
