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

It was okay, short flight so nothing much to comment.

The original email I received and flight that I paid for was for Japan Airlines. Since JAL is a partner with American, I ended up on an American Airlines plane. This would not be a problem, except that JAL allows 2 check in bags for free and American only allows 1. A $100.00 unexpected expense was very disturbing, especially since I will have to pay it again on my way home. I feel like it was a bait and switch. I never would have chosen American Airlines if I had known that I would have to pay $200.00 in baggage fees, above and beyond my airfare. Secondly, the check in counter representative did not realize that I had TSA pre-check, so I had to return to the check-in desk on a different floor to get a new boarding pass. The AA representative helping at the check-in kiosks was very helpful, kind, polite, and professional when I returned for the new boarding pass. Thirdly, the crew was not as friendly as I have experienced on other airlines. Their tone when speaking to other passengers was not always polite. The food was better than I expected. However, I am used to having a station where one can serve themselves water, juice or grab a snack. That was not the case on this flight. Truly makes me think twice about booking with American Airlines. I am very disappointed.

Crews are rude and short. Example: after my drink and was ready to prep my bed to rest. I tried to give my empty glasses to the steward while she was playing her card game on her iPad. The steward told me to take the glass back to my table instead of taking the glass out of my hand. Compare Japanese steward it’s like heaven and hell.
