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
Korean air has a little bit more seating space than Asiana air.
There was a lot of partial tv shows but not enough to last the flight. The food was incredible! The crew were so helpful and patient. Lots more space than what I usually get on an international flight. Very comfortable!
Stingy on the drinks - 15 hour direct flight and could barely get attention for some water
Unfortunately, there has been a boarding and departure delay. However, as usual, the flight arrived earlier than the scheduled. There has been a turbulence in-between, it’s unavoidable. I couldn’t complain them.
Not many people, so you can lay down on two seats
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.
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.
Been flying with China Airline over years many times. Good experience with them, no issues.
China Airlines crews are very excellent doing their job. Very friendly and hardworking. I will always choose China Airlines over and over. Thank you all for making my flight comfortable. God bless to all the staff. :)
I don’t think I’ll be flying them again. Tight seats, no flowing air or air nozzles that you can turn air on you, for those who could have motion sickness this would be your worst nightmare. The pilot was great and experienced (which is what you want when flying 12 hours) overall I’m thankful knowledgeable pilots!
My ticket did not indication which group I was in for boarding; the gate attended help me
Better screens, it would have been nice to have more comfortable seats.
2nd major delay due to maintenance issues. 1st delay missed my connecting flight.
It was great, but my bag was not loaded onto the connecting flight. I'm currently getting it resolved. If this isn't a problem, everything else was excellent.
Very clean ,flight attendants very professional,nice , Boarding was very easy
The plane hasnt left im stuck in seatle still my flight has been grounded for almost 5 hours
My luggage didn’t arrive with my flight. Flight was delayed by nearly 2 hours while we sat on the plane and I almost missed my connecting flight and subsequently missed the last train from the airport so it took me another 2 hours to get to my destination after arriving, Crew skipped me several times when offering beverages, and I couldn’t get their attention at times because they wouldn’t even make eye contact with me. They didn’t give me a form for disembarking so I had to go to the back of the line after waiting an eternity for immigration. Paid for on flight wi- fi that didn’t work for most of the flight.
Love flying Asiana. Been using it for over a decade now.
I had a bad experience coming from America to Thailand. On my connecting flight my check in suitcase was not put on the departing aircraft, I received my suitcase 24 hours after arriving in Bangkok and when I open my luggage my hand swelled up. The next morning when I put on an outfit from my suitcase my face swelled up and became numb. My entire vacation was ruined it seems that some kind of chemical was sprayed into suitcase and ruined my clothes and got me sick. The staff at my hotel called the airline and spoke to someone and they told me to file a complaint and gave my a website to do so. I did not file a complaint I felt like it would have fell on death ears. I had to throw away my brand new vacation clothes and suitcase and I had the worst vacation ever due to this happening to me.
The staff was courteous and the flight was very smooth. It was so nice to see the captain greeting the passengers at the end of the flights.
The beefsteak on the lunch menu was excellent! I usually do not eat airplane food. I loved it.
Perfect flight both ways. On time, courteous staff, plane comfortable and cool. Best domestic flights I’ve had in awhile.
The food was terrible especially for a 15 hour international flight. The crew was unpleasant as well.
Really low quality food especially for an international flight. The crew also was surprisingly unpleasant except couple of ladies. I know we were not in first class but that’s no reason to treat customers as less.
Flight delayed for two and half hours and then canceled altogether due to mechanical issues. No mechanic onsite to fix so had to send one from LAX.
Quick check in. Everything went smooth. I don't know what can be done about airline food.
Crew was good. The reservation got mixed up and they didn't have my TSA number. I am also a Silver Medallion and wasn't able to use Sky Priority.
Delta made it easy, comfortable and timely. The crew was fantastic.
This route with Delta always has delays or is cancelled. Aircrafts seem smaller and older. I fly Delta quite a bit - haven’t had issues with the international flights. But this route has always been the troublesome one
Nothing special. The crew never went out of their way for anything.
Three seats in first class were broken and while they were able to still acommodate us it was looking very touch and go and they had others they could not acommodate
For the price, it was a really good experience. There was no entertainment on board, so I couldn't really rate this, and I didn't order a meal. I appreciated that there was a free glass of wine.
Short flight. Everything was fine except the flight was delayed twice for a total of an hour.
My flight from New York to Canada and Canada to Brisbane was canceled, so I had to take united airlines instead flight from New York to Dubai then layover in Dubai 8 hours then from Dubai to Brisbane it was extremely difficult for me , it was a nightmare flying with Canadian airlines unfortunately.
I found the boarding easy and my seat was very comfortable as I had a lot of leg room. I am not too happy that I no longer have lounge access even though I used to get it with my TD credit card.
Flight cancelled. Major disruption to our travel. Do not use Air Canada from KC. To few flights.
Real smooth and easy, Real good leg room in coach!
There labor disputes cancelled my flight less than 24 hours before my boarding time but there customer service/website was easy enough to navigate and they rebooked me for no upcharge.
Re luggage I carried a backpack only. I did not check any bags in. However there were other passengers with carry on luggage going in the plane. My question is why are others allowed to have a carry on luggage inside the plane? Shouldn’t they have dropped it off at the gate? I’m asking because I could have brought the same thing instead of a backpack only. Please clarify for future reference. Thank you.
Like the service. Very hard to communicate or contact when have problems
Very bad, flight was cancelled due to strike and staff was unable to rebook us
