Airline reviews

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.

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.

Excellent overall, the staffs and amenities were delightful even using the outdated aircraft.

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

Nice amount of space in economy seat. Very attentive attendants that allowed a seat change that helped several people. Morning meal could have been better.

The foods were lacking in both quality and quantity. I was starving.

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.

The flights were on time and the cabin crew were very nice. The only downside was that the food was not good.

I like the intention and service of the flight crew. Japanese values were observed and appreciated as a customer.

Excellent service, excellent food and beverage options, plenty of legroom
