The crew was incredible. The pilots were so fantastic. The smoothest landing I’ve ever experienced.

The crew was incredible. The pilots were so fantastic. The smoothest landing I’ve ever experienced.

The flight attendants are always fantastic. My only issue – and it was on my Haneda to Vancouver flight – same as my Vancouver to Osaka flight – I had a confirmed special meal and they had no record of it on board. I tried to confirm it with the gate agent in Fukuoka, where I initiated the day, because of the mess up a month ago, and she said that they can't confirm special meals. I'd have to see when I got on board.

Great transfer of luggage from my flight with Osaka to Tokyo then Tokyo to final destination in Chicago

Great experienced staff and very pleasant compared to some other international airlines

Flight was good and comfortable, even for long haul economy. No complaints.

Check in was fast, lounge was good. Special section for ANA passengers in the Plaza Premium lounge. Boarding was organized and quick. Crew was very nice. They ran out of the Japanese meal so they asked me to switch to the international meal. Beef was room temperature and not hot. It tasted ok. Japanese meal was served hot. Movies were not great. Chair was very old and recline was not good. TV monitor was very old and not HD. Plane layout in business was 2-2-2. Should switch to the 1-2-1 layout for more privacy. Overall flight was average to good. Service was good but hard product should be updated to compete against much nicer Taiwanese airlines.

They lost my luggage on the inbound flight and then lost it again on this flight. I called online travel agent to change earlier flight to get a longer layover in Vancouver but ANA denied it

Suite lounge in Honolulu is very exclusive and boarding from the lounge into the plane is unique. First suites were huge and comfortable. Japanese meal is like a high end omakase meal. All the staff were very kind and provided sophisticated service. Fast Track upon landing was appreciated but not needed this time because immigration was so empty and easy.

I like the service very much. The food just okay but maybe different culture who like, who don't like.

Everything was excellent. Only the fish entree in the Japanese meal was overcooked and quite dry but everything else was great

I was so hungry , from Boston to Tokyo, only 2 big food .

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

The crew was nice, the food could be better, and at least 2 bathroom stalls were out of service.

The crew was attentive and provided everything I needed. The food in business class was excellent.

Good experience for economy transpacific. Reasonable comfortable seats. Food was not as good as I expected or had on other prior transpacific flights but likely attribute that to rising cost of supplies. Staff is courteous. Overall, very good.

Good the crew was nice very kind and very helpful

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.

I felt that the customer service improved compared to a several years ago.

I traveled business class from Lax to Narita flight Jl61. The crew was attentive and polite. Food was good quality and service was as it should be. Narita to Bengaluru Jl753was another story in business class. The cabin was darkened for the 9hr:30min flight, food was mediocre, service was below standard and crew can't speak English to save their lives. When you ask for noodles soup from Ala carte they gave cup of noodles while Lax to Narita i was served the best Ramen noodles in a big bowl. Why the disparity on this leg of the journey.....or is it because there were mostly Indian passengers and it really did not matter to Jal to bother as its a poor country and Indians refrain from speaking up? A good airline but differentiation like this brings their reputation and business down.
