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

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?

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

On time. Friendly and helpful flight attendants. The plane was clean. Having a wine available would have been nice.

Your staff was exceptional. Could teach the other airlines-rules on etiquette, and service. Excellent landings on flights, carried out by your pilots. Only complaint is long delay on return flight in Beijing, onto Vancouver.

Worst than I expected, crew was not attentive, meal was as disgusting , they didn’t even drink selections as they would to other passengers. I felt discriminated

cannot get seat information for LAX to IAH when check in in XI,AN

UA is ok. But check in was a very bad experience

I hate that you cannot check in online and when you are at the airport, there aren't any aisle seats left. Also, they could work a little on subtitles for their movies (not everyone is a native English speaker).

Nothing to complain of, the only reason I am not giving better marks is that I am used to flying with ANA and they are the top.

It's terrible that we can't do online check in because we didn't buy the tickets directly from Air china. It was not explained until I contacted Chatdeal and we could not sit together.

Communication between the captain/crew and the passengers needs to be improved.

Food and service are good. Bathroom was lack of lotions and cleaning. That should be improved.
