I always enjoy flying with Japanese Airlines. The whole experience is always a pleasure. This flight was no exception. Thank you Kayak for making it so easy to decide.

Overall, it was ok. The attendants are nice. It was a short flight, and I did not use the restrooms. What I was frustrated was the check-in. I was to fly from ATL to Chicago (American) then change to Japan Airline to go to Japan. I checked in, but I only got a boarding pass for the flight from Atlanta to Chicago. It said I would need to check in for a flight to Japan on Japan Airline site. When I tried to check in on JAL website, it said I need to check in American... It was very confusing.

service was excellent. crew very polite, courteous, and good service especially to passengers like me who is a wheelchair passenger

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

Very comfortab flight. The flight crew and service was terrific. The food was average at best.

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

Check in procedure is harder than with other airlines, infotainment system is outdated

great experience - staff were kind and attentive and food was excellent. very comfortable flight that felt much shorter than 14 hours.

JAL is an exceptional airline that shows the true heart of Japanese omotenashi service. If the option is available I’ll always chose it

Impeccable services, excellent meals, on-time flights, what more can you ask for!
