Good pilot and crew. No food or beverage on this flight Entertainment is via own device thru plane's wifi.

My plans changed and I tried to cancel or change the flight for credit but was giving the run around and denied . Not great

Excellent service, excellent food and beverage options, plenty of leg room

Checking in as an international flyer is a bit tedious

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
