It’s great, long flight and arrive safe at destination

Everything was excellent as I expected. They also had a very caring crew. I had a headache and asked a Tylenol. The crew members kept checking with me how I was doing.

They were trying to get people to check luggage because the over head compartments were full but when we boarded there were lots of empty places that people could have put the luggage.

I can't believe they put my wife and I in the two middle seats! It is a very long flight and we had single flyers on either side of us blocking the way to the bathroom! There's no reason to not give one of us the isle seat so we could have managed bathroom needs and snacks with convenience. So I think very poorly of Korean air to put us both in the middle, I've never had that happen before and will probably avoid this airline in the future because of this. We tried to have them change it but they didn't so you pretty much lost a customer because of it.

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?

One of the flight attendants stepped on my foot. I was on the aisle seat. A lady inside needed to get out. So Instood. Just then, a flight attentendant came wuicklybtheoughbthe aisle and stepprd on my sock covered toes. I let out a small sound. She stopped momentarily, but didn’t ask how I was just took off of the aisle. Never came back to see how I was. Fortunately, I was not really hurt other than a slight soreness in my toes. But I found that to be very negligent.

This flight was a superior flight in all regards. Extremely pleasant experience.

Korean Air is unlike any other major airline I have flown with. The grace and respect that the staff has from check in to de-boarding is unmatched. The flight attendants this time were especially wonderful to my five little children. They helped us rearrange to more suitable seating, brought our children’s meals, and patiently waited for them in the aisles when they had to use the bathroom. We felt so welcome and comfortable. I really appreciate the meal voucher when our flight was delayed. I am grateful to have had such an stress-free experience.

It's good overall. Flight was packed. Inflight entertainment choices were lacking.

I liked the service. The touch screen needs improvement as well as movie choices.

My only suggestion is a way to not be woken up for food. … like maybe something you can place on you if you’d prefer to miss food than be woken up

After each meal was served I didn't see any flight attendant offer coffee or tea to the passengers after the initial drinks were offered. Other flights I had been one it was standard procedure to offer hot drinks after the meal service.

It was great. It was my first time with Cathay Pacific and I really recommend.

Selected ovo lacto meal because I’m ok with milk products but not any meat. It was terrible. We had the same selection back in October when we had traveled and it was pretty good at that time. It was gross this time.

I was mid plane and they were already out of the main beef entree....ugh!

Flight delayed first from bad weather, then after boarding there was a problem with the plane. We had to get off and onto another plane...connections were missed and the trip took an additional 10 hours!! Pre-paid seatting was not honored due ro last minute carrier changes. Most of the trip was on Japan Airline.

Vegetarian options should be included with every meal. Even just simple steamed vegetables and whole grains would capture a wide audience.

Cramped, hot and the plane was grubby. Also the plane was an hour late and it took an hour to get my luggage once I got to LAX.

Extensive delays, poor organization to board people, as it felt like chaos to get inside of the plane. No lines, everyone gathering together like a mayhem, very confusing. Passengers out of hand and rude, which is not the airlines fault. However, there should be rules, e.g., not letting one passenger take 2+ spots in the overhead bin.
