Food is what you expect on a plane. Nothing gluten free. But that is expected. Drinks, apple juice, was fine. Seat, what I expected. Fine.

Food is what you expect on a plane. Nothing gluten free. But that is expected. Drinks, apple juice, was fine. Seat, what I expected. Fine.

The flight took off an hour late which made the connection concerning

The flight from Dallas to Tokyo was not on Japan Airlines. It was on American Airlines. Very disappointed that we did not fly on Japan Airlines. Will not be using you liars again. I’ll just book direct from the airline next time. Wish you could make this right and has us fly on Japan Air when heading back home to the US.

They made nearly everyone check their bag because the overhead bins are way too small. Extremely inconvenient

It was what i expected. I like the movies you can access from your phone. It would be nice if there was a gluten free snack offered. But I did bring my own snack knowing there would not be a gluten free option

Ontario airport boarding was very easy to park and access, is clean and TSA took 10 minutes total. Check-in was a breeze and cruise was very nice.

We got delayed getting out of DFW for broken overhead bins. Once the flight got underway the captain kept the seatbelt sign lit the entire flight despite little perceptible turbulence, preventing use of the rest rooms and any sort of refreshment service in the main cabin.

There were flight delays making our flight arrive at our destination after midnight didn’t seem to have enough crew or airplanes for the flights laid over in Dallas should’ve had plenty of time to make it to our next flight only made it because that flight was also delayed because our plane wasn’t even at the airport yet overall have not had a good experience on American

Seat comfort was poor (no lumbar or lower back support).

The passenger in front of of me reclined their seat back all the way the entire flight. Their headrest was in my face the entire flight! I barely had room for the little plastic cup of water to fit on my tray table; can you make the seats and space between the rows any smaller??? You can’t even get up to use the restroom! Worst flight I’ve had in a very long time!
