There were no vegetarian options on flight from India. Then on the next flight there was no chosen entree available. Movie selection was mediocre

It was fine but my trip from Narita Japan to L.A kind of mediocre because did not get the assigned window seat.

It was good overall. What I liked most was the restrooms. Compared to other airlines, the restrooms seem larger and look clean. The seats also look clean. The attendants are nice, except one time during the flight. I was sitting on aisle and a man sitting window. He asked an attendant for a snack. She told him to go ahead and get some snack from the section with food storage (I am not sure how it is called). So, I had to get up to let him get out from his seat. Why she did not bring him some snacks so that I would not have to move, I do not know... I was kind of surprised how inconsiderate the attendant was.

JOKE of a company with the most Ridiculous policies. JAL is amazing, KAYAK/UNDERPRICER is the worst company I have ever dealt with, NEVER AGAIN

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.

Roomy airlines. Friendly staff. Timely service. Temp was warm during the flight.

LAX to San Francisco under UA was sooooo stressful! Flights was delayed and no assistance from the airline to the next flight. Flew UA twice and both flights highly distressful.

I thought I bought the ticket directly through Kayak not a 3rd party

I like that we made it faster than regularly scheduled. Everything else was poor. The boarding was slow and chaotic. One person was screaming instructions to people that didn’t understand and there was only one camera so boarding was slow. The crew was not very friendly and one stewardess was extremely rude to everyone the entire flight. The food was not good and not themed to the country we were going to like every international flight I’ve taken. Lastly the seats were awful. After this flight I would never recommend United and will actively avoid booking another flight through them.

When I checked in, it printed two bag tags. The helper said they would cancel the other. They canceled both and my bag was left behind

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.

Checking bag at terminal was horrible. No agents to check us in and only 1 kiosk working. Boarding went ok. Crew onboard was very scattered rained. Missed our row while serving and then didn’t see them hardly again.

Crew was amazing, takeoff wonderful. The bathroom was disgusting from before takeoff the odor made the flight uncomfortable as you could smell the bathroom from the center of the plane where we were sitting. Smelled like raw sewage. My daughter was throwing up as we landed due to the smell and horrible turbulence as we approached Newark.

Airline tickets are not cheap. You expect reliable competent service. Thanks to canceled flights and botched transfers we arrived at our destination two days late. This is not acceptable

Horrible! Several delays and then was cancelled! I spent over 24 hours in the airport and was unable to get a hotel or food voucher.

The entertainment they offer could use some games, and maybe they could add some cookies to the snack menu. And the automated messages are a bit repetitive. But it was comfortable temperature wise and the seats were comfortable. The crew is very polite and helpful

The entertainment is a bit limited, it would be better if they added some games to play besides the movies and tv shows. But the seats are comfortable and the crew is polite

This planes staff was top tier. Everything went great and had a great flight home.

Food was great. Staff was phenomenal. Seats were a bit hard and could use a lot more entertainment options as far as movies to choose from. WiFi was good. Overall great trip.

This was an overnight flight, and in the morning they did know coffee service. How you can throw passengers in a San Francisco airport at 5:40 a.m. in the morning and not giving them Coffee is a crime.

I was promised by United Airline (operated by ANA) that I will be seated together with my kids as I am the only adult flying with two minors. We did not get seats together in our 11 hours flight from LA to Tokyo. When asked at the gate, ANA representative said United Airline should have informed them that there is a parent flying with two minors. He said they can’t do anything in the system as the flight is full. He ask me to ask passengers next to me and the kids if they are willing to change seats. This is ridiculous! However, I went in the flight and asked other passages but no one willing to change seats. 11 hours and we were seating separately. I was very disappointed with this. It made things super inconvenient for me.

Flight had mechanical issues and it was delayed 30 mins - some of us boarded and then had to deplane.

technology worked well and everything ran smoothly. The seats are quite cramped so please don't try to re-engineer the cabin to squeeze more bodies on board.

Delayed flight more than I hour. When boarding we spent some additional time on the plane before takeoff ....

Flight was delayed due to connecting passengers. Lack of snack options bad. Sitting in Aisle, last cart run pulled the cart directly into my knee. Rude awakening.

We sat on plane at gate delayed without communication as to why we were just sitting there

Agency very bad had to cancelled my booking too many changes in the flight changed my flight to 1 week

Trash. Sat on the runway for 40 mins…missed connecting flight because of it now I’m stuck. Thanks…a whole fkn lot.

The flight was delayed significantly and we sat on runway after landing for awhile. Best thing was the flight attendant, Jenny, in first class, who was very professional and attentive. She was excellent - the rest of the flight was not.

Crew were professional and kind. The flight was smooth. But... The internet, which we paid 35 dollars for, did not work for most of the flight. This made providing media for our child an uncomfortable hassle.

Overall fine. Seemed like one of the older model planes? Crew was mostly very kind, though some of the female attendants were a rather abrupt during the food service.

1didnt have wheel chair I ordered wheel chair in my ticket flight

Flight was overbooked and seats assigned to multiple passengers. Delay 1 hour to sort out.

Good but I don’t received my bags yet is been 5days still no update

It was pretty straight forward, no glitches or hidden costs

It was a short flight so, everything went smoothly and we got to where we needed to be safely.

Didnt make it on flight. Flight was delayed. Then had to get rebooked for a flight that was 8 hours later. Guess who had to wait for 8 hours at the airport?

Didn’t make it on the flight. Delayed then had to be rebooked, which in turn had me waiting at the airport for another 8 hours before next flight

No TV on the flight. The charging outlet was not working. No food, even a sandwich. The served orange was poor quality.

Selected seats 5 months prior to date. Had email confirmation and seats were not honoured. Family did not sit together

Loved and was pleasantly surprised by the food!! Request Lufthansa to help transiting passengers at Munich (confusion whether to go thru passport control or not).
