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

First of all it’s an American Airline flight not JAL as advertised. Code share is deceiving. Seats are uncomfortable. Stewards in our section were not friendly, felt rude at times.

Lovely flight attendants comfort in Economy Premium. Very attentive and kind I would choose JAL again for sure!

I enjoy flying American airlines. I tried to book American airline when I’m flying most places.

After boarding it was fine. Premium economy was not available for one long leg. Economy was very uncomfortable. They need to fix these issues. Planes are old. It gets more and more dangerous due to fatigue of plane parts. They need to upgrade before something goes wrong with the plane. Hazardous. Hari S Doss
