My ONLY complaint with Japan Airlines is their in-floght movie options. The choices were very limited and skewed towards lesser movies that are pretty much unknown. On a 13 hour flight I'm dependent on there being a solid list of decent films to pick from. The poor choices made the flight seem twice as long. Next time I'll bring a fully loaded iPad for my movies.

Very courteous and professional flight attendants. At least from Delhi to Tokyo leg where a good number of passengers are of Indian origin should have some items of Indian cuisine on the menu other than that great experience.

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.

Crew hospitality was as expected of a Japanese carrier, however the foods were lacking. The dinner options provided all contained pork and the breakfast was lacking in both quality and volume. I was starving throughout the trip.

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.

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

Excellent service, excellent food and beverage options, plenty of leg room

Checking in as an international flyer is a bit tedious

I was so hungry , from Boston to Tokyo, only 2 big food .

Good experience for economy transpacific. Reasonable comfortable seats. Food was not as good as I expected or had on other prior transpacific flights but likely attribute that to rising cost of supplies. Staff is courteous. Overall, very good.

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.

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.

Boarding was good. Inflight service was good. Alcoholic drinks could have been served free.

Suite lounge in Honolulu is the best lounge in Honolulu. I love the huge bathrooms in ANA first Class on the A380 Honu plane. Japanese meal was outstanding and service was amazing. Everything was just excellent. Can’t wait to fly again

Their was $200 charge for 2nd luggage, airplane very new and flight smooth. Flight time seem faster then Asian stoping Korea then china.

Seat was broken. Check in was not possible until we reached the gate, by then we were separated.

The food was not great; but I don’t expect much from airline food. However, the staff was incredible! I had gotten to the gate when I realized I had left my computer at the security checkpoint! I told a staff member and she said, “well, you will miss this flight if you go back to get it” It was a long way from the gate. I asked if I might get on the next flight. She sent for another staff member, and he took me to the gate desk. He found an open seat, and said,”okay, go run to get your computer, I will get you a new boarding pass.” I rran back, retrieved my computer, and returned to the gate. It was closed, but I found the gate nearby where the next ANA flight was leaving. Another staff member was ready for me, and printed me a new pass, and even made sure I still had an aisle seat that I requested! I got in line and continued my trip. These people are amazing, helpful, and friendly. My trip could have been ruined, or postponed at a great expense, but they saved the day! 5 stars!!!!

Cree was organized and pleasant. Plane had good seating but as it’s a shuttle toilets hadn’t been thoroughly cleaned (eg. bins too full)

I liked that my son and I were reseated next to each other (we had different bookings). I liked that it was a directg flight and mostly on time. I liked that you provided pillows and blankets. Flight attendants were generally courteous. The messaging through wifi did not work well. The food was not good. Seats are very narrow and I felt slightly claustraphobic in the window seat.

Overall a good experience, but no wifi available for free or for purchase and we got wet from condensation or other water source during descent.

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

not sure why you ask about food, I n3ver get food on flights except maybe cookies or pretzels. wifi was slow and in and out most of the flight not good.

The crew was very attentive through out the flight. Seats were comfortable, nice flight bag with pillow and blanket. Food was okay, since it was a overnight flight seemed to go by fast.

The flight attendant on my side of business class seemed like a novice and did not provide good service. Otherwise the flight was good and the entertainment system was very good. No free WiFi.

Cancelled BOYH legs of our flight home 30 min before initial boarding

Cancelled the flight half hour before boarding. Then cancelled the connecting flight too.

Left early arrived early..right amount of talking from pilots..of course had to love the biscuit and water!

I would like a refund for the extra cost the seat I paid for. An oversized person sat next to me and I couldn’t fit on my seat and had to move to another seat.

Boarding gate at LAX was too crowded—two gates next to one another

The flight was delayed about an hour for a maintenance specialist to approve the maintenance repair

This flight was delayed but it worked in my favor because my Atlanta to Dallas flight was delayed.

I did not like anything because the flight was cancelled yesterday and I did not get to arrive on time in Toronto as I was rebooked with another airline. This caused me to be really stressed out as I am an individual with back injury and to be forced to stay longer in an airport to accommodate a change of airline and the transfers associated with it Due to this I am probably not going to book through your website to eliminate this potentially chaos in the future

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.
