AAAAHHHH... It was shocking in a very positive way, the attention to detail, the courtesy, the manners of all personnel on board, the constant honest smiling. You can see and feel they take pride in all they do no matter how trivial. The plane in general was very comfortable. I can't wait to do it again

AAAAHHHH... It was shocking in a very positive way, the attention to detail, the courtesy, the manners of all personnel on board, the constant honest smiling. You can see and feel they take pride in all they do no matter how trivial. The plane in general was very comfortable. I can't wait to do it again

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.

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.

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?

Plane took off on time and I had the whole row to myself!

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

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!

Overall, a solid flight experience. Boarding was quick and efficient, even with a full and overbooked flight. The flight crew did a great job providing attentive and friendly service throughout. I flew in economy, and while the seats were acceptable, they could definitely use more cushioning, especially for a 14-hour flight. By the end, it was quite uncomfortable to remain seated. Legroom was also limited, particularly with a bag stored under the seat and the passenger in front reclining. That said, everything else went smoothly, and I appreciated the professionalism of the crew.

The flight was delightful overall. The check-in and boarding were on smooth and on time. Amenities and staffs were elevated. However, if glasses were served instead of cups, there should be a complete premium.

Sure I would’ve liked a little more space, but it was better than economy. I bring my own food because I have food allergies it would be nice if they offered larger salads or more vegetables instead of starch it was really a good flight. I don’t wanna complain. I’m grateful to fly at all safely. Thank you to the pilots.

Flight crews are very attentive and polite. Cabin and toilets are clean. Food is above average for economy class. We missed our connecting flights because the first flight was delayed, the ground crews at Tokyo were very helpful, providing all the information and support (including cash for our train ticket) to get us to our destination. Very impressive. No wonder they are always at the top ten lists.

Excellent! So happy that the crew members were so helpful and friendly and able to understandably communicate. They’re very receptive with someone like me, with disability. I love that I did not even have to ask for luggage help like, having to place and take down my carry-on luggage in and out of the over-head compartment. Hope, help is extended to disabled passenger(s) through out class classifications they’ve bought; economy or business class it might be. As a disabled person myself, I’m truly of great appreciation of this kind of help. Means a lot !!! Thank you so very much JAL crew. You out done others on this customer service part of the trip. Please continue to do so. From now on, I’ll choose JAL as my airline whenever I have to fly to any southeast asian countries. And I will disseminate my excellent travel experience with you to others.

My only complaint is that the flight attendant that I encountered was not receptive, unhappy to help me out prompted for help with my carry-on luggage to be put up into the over-head compartment. At time of booking, I’ve informed the customer service about my medical-surgical history necessitating assistance in carrying luggage(s)/baggage(s) especially lifting over head. I know crews’ policy of doing such. But, there should be exception(s) to that rule; a consideration for disabled people.. Especially noting given the passenger’s med/surg’s history. Hope, something will come out of this survey. Thank you for your kind understanding and cooperation regarding this issue. So I can still continue flying with any airlines in the near future.

American Airlines food is horrible. Also, paid to fly JAL on all segments, but received a much lower quality. I was disappointed to learn that we would be using American Airlines on this flight, which has less comfort, entertainment, choices, and lower standard of service. Overall not satisfied.

Food was very mediocre. Economy is pretty uncomfortable. Crew was excellent and responsive.

Not as good as I expected, I couldn't use the screen to watch movies or anything else because it wasn't 'STEADY' AT ALL, it moved every single time that the passenger who sat on that seat moved, that caused me fell dizzy and nauseous when I tried to use it, so I ended up with only sleeping and eating with no entertainment all my haul flight on premium economy seat, plus the passenger who sat next to me, she just loved to spread her very long hair down on my shoulder, face, arm, sometimes her hair just whacked my face till I really wanted to offer her my hairband!, super annoying 😑 and that my bad experience with that flight.

My plans changed and I tried to cancel or change the flight for credit but was giving the run around and denied . Not great

The ladies are great seats should be a little bigger!

Couple of hours delayed, we had to re-booked our Shinkansen reservation twice. United Aiines need to improve their time!

The check-in started 3 minutes early; there were people lining up a half hour before. I was third, and I got checked in and passes in hand for my connection as well; I walked away from the desk one minute before it was even supposed to be open. Amazing. That said, the food on the first leg of my trip was not good, and I didn’t finish it. Second leg, it was tasty. You get a cup of Häagen-Dazs after dinner. The staff were polite and helpful. Will use again.

Crew was fantastic. Seats were not completely lay flat but still comfortable to watch a show. International food was lobster which was very big but a little tough. The scallop appetizer was delicious. Loved the individual air conditioning vent at each seat. Flight overall was very smooth and very good.

Staff was friendly but couldn't find way to track them down during flight. Food tried to be gourmet but was just too unusual. Business class seats were hard. Even sitting on the pillow, was still painful. Have to give them credit for on-time flights and decent gate area.

Flight was excellent. Transfer from one airport to another airport for a connecting flight was difficult and stressful.

Overall good except the checkin process at Bangkok airport. Can ANA explain why the line for business class is longer than that for economy? I, BC passenger, had to move from BC line to economy line to get faster service.

Matsuyama to Tokyo is basically a puddle jumper flight, so it was as good as one should expect. No meal, no entertainment, and none expected.

The staff is amazing, I cannot stress that enough! The food is really good and snacks at stations to take for yourselves. Economy seating is fine, not the most comfortable, but our friends in Premium Economy said they were very comfortable! Decent entertainment options, but being built in, you have to use their cheap headsets unless you have your own plug in ones. I only have Bluetooth earbuds.

Seats were extremely cramped even for economy. Food was atrocious. Crew was fine but no follow up, additional drinks offered etc. For a 14 hour flight I expected more.

Some crew were unfriendly or in some cases just straight up rude.

Booked through Kayak Business, had a seat in middle and towards back due to booking rate, not comfortable.

Was great in general, try to respect time and excuses when slight changes have been made, appreciated!

A long delay. Don't travel late in the day.

Super friendly with lots of drink options an entertainment. Friendly crew.

Standard flight with a drinks and a snack- overall very quick flight. The flight attendants were very strict, bordered on rude.

Outstanding service, efficient & friendly crew, flight was safe, comfortable & on time

United Airline crews were very friendly and very attentive. 12 hours flight was gone like in a shorter one.

Delayed - weather wasn't bad at either end. Also sat on tarmac in ORD.

Food was surprisingly delicious. Space in the seat is horrible when the seating front is reclined. Movie offerings were terrible. Crew was friendly and helpful.

shittiest airline in the hemisphere. To improve - start thinking you're flying people, not cattle

Easy boarding, inflight refreshments came on time and comfortable seat

It was good that our flight left early. It was a nice smooth flight and landing.

All good……but luggage didn’t make it on the airplane. Had to wait 3 days. Was a bummer.

Small suitcase used for carryon the last time was refused by boarding crew this time. Appears to be at the discretion and mood of the person on the day. Flight was only half booked, there would have been no problem with space.

It was a problem because there was a delay where we sat before taking off from newark,then when landed in Toronto we sat on tarmac and they wouldn't let us out for a long period of time. When we finally were released to the airport in Toronto the attendant scanned our boarding pass that we were here for our connection to Brazil. We ran all the way to the gate and they said at the gate the door is shut so we can not let you on the plane. We explained that we were checked in by the attendant when we arrived at Toronto airport to go to Brazil and they should not have shut the door. We were ignored at the gate

Flight home was delayed multiple times, did not get home until 2am

the check-in lady at ORD was extremely rude and unprofessional. very disappointed as it was supposed to be a celebration for my wife's birthday and it really put a damper on things. if i wanted to be treated like trash, i would have flown Economy! (as opposed to business class)

My original flight was cancelled and then rebooked four hours later on a recovery flight, but I was checked in as stanby and had no seats so as a family of four we were concerned about not being seated altogether. Our flight then got delayed by another 1.5 hours and when seats were assigned at the gate, three of the four of us were together and we could get my wife closer, they offered no assistance.

The plane was very cramped to point there was no way not to touch person beside you and a stewardess screamed at my son when I touched her arm to get her attention to let her know she forgot to give him his dinner when she passed him and gave a dinner to passenger behind him. Very inappropriate response and She never came back to apologize and other stewardess said she was sorry “if I felt” she was inappropriate. Horrible experience and she should be reprimanded for her behavior
