Their in0flight movie selection is limited in size and poor in quality.

Japan airlines is a great airline. One of my favorites. The only issue I had was that I only pescatarian or I can eat vegetables, pasta, etc and both choices of meals were chicken or red meat. Most of other airlines have meat or pasta. Also usually I get an alert to order a meal prior to fly and this time I did not get one. Other than that everything was wonderful.

Boarding and crew service were excellent. Food was mediocre, not as good as our last trip four years ago.

Great level of comfort and highly professional and friendly flight crew. Keep up the great service.

It was amazing. Japan is lovely. I hope to go again. Thank you for everything.

My first issue is the lack of clarity with the airlines. I know that Japan airlines and American Airlines are partners, but I couldn’t figure out which airline I was flying with. I got the flight info for Japan airlines and ended up on American. After my Kayak booking (via Underpricer) I got a phone call to see if I wanted up choose a seat and pay for luggage fees. both American and Japan airlines offer 2 carryons and 2 regular luggage checked in at no additional fees to Tokyo. Having already done my research, I opted out on their “Offer” and just contacted the airline directly to pay for upgraded seats (Which were cheaper than the Underpricer deal) My top complaint was the flight delay from HND to LAX it wasn’t until I had already made my unchangable airport drop off car reservations , that I received 3 hour flight delay email. I was forced to be there 6 hours prior to the departure. They were kind enough to give us a limited restaurant food voucher- which was 1900 yen ( I saw Delta food vouchers were 2000 yen). My teen and I ate food court pizza. The flight arrived when expected, The food was mid on the flight. I slept and woke up about 1.5 hours to LAX. I had waffles ( which also contained 1 mushroom and 1 tomato in the same tray) and 3 small pieces of fruit. All went well, just remember to check on your 3rd party ticket companies. Some seem to be sneaky All in all it was a very long day, we made it back safe.

Horrible like always, flight was supposed to be at 11:40am, we ended up getting a different airplane at 3:25pm.

I have been flying with JAL a few times, crews service, food, overall comfort even with economy, I would rate it the top three airlines. None of any American carriers can provide such excellent service.

service was excellent. crew very polite, courteous, and good service especially to passengers like me who is a wheelchair passenger
