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Check in procedure is harder than with other airlines, infotainment system is outdated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

"The Room" is the only way to fly. The service was excellent and the stewardesses we all gorgeous and friendly. The boarding process was delayed and the attendants at the airport were not the best.

The flights with ANA were great. The flights with United, not so much.

Attendants were very kind and frequently offered water and snacks. Food was excellent. For some reason, my IFE system would not play dialogue for any media despite my efforts to change to different language voiceovers, restart the system, etc. so I could not watch any videos.

Staff at gate and crew on plane efficient and friendly.

As always, there is that one or two flight attendants that could be better.

It was good. The crew was efficient, food was good

Vegetarian options were not that great. However, the crew and service was awesome

Entertainment was good , comfort on airplane easy hoarding food and drinks was good and a friendly and good service of flight staff

I was good seat to keep stretch my legs . but couldn’t keep my bag in my hand . because they told me can’t keep my seat is no holder , because no seat fronts of us. wish I can put my leg on something higher. but instead of that everything goood.

Good airlines btu ORL airport messed up the return flight for me. Checking out a connecting flight pax is unacceptable.

It was ok, but not what it was like 20 years ago

My experience was great overall. Tanya was particularly friendly and helpful the entire trip. I was very pleased with her customer service skills. The plane was an older aircraft but the entire way was comfortable with barely any turbulence at all. Qantas should speed up its fleet renovation. Totally recommend using this airline.

Very good as always, stand out airline. The passengers whom choose to stuff baggage that otherwise should be checked-in is a real bother but that's not the airlines doing. A real frustration that passengers just don't want to check-in luggage. This is a pet hate unfortunately.

I got upgraded from economy to business, and the experience was outstanding

It was very nice. I will try to fly with Qantas whenever I can.

The flight was good, long obviously but smooth. The seats are pretty small, definitely notice a difference for long haul compared to Emirates or Cathay Pacific it’s more like medium haul seating for space. Food options were good, children’s meals were good for my fussy 3yo.

It’s a very long flight and there are so many people on board. Perhaps a warm washcloth now and then to freshen up

The staff we fantastic and seemed to work very well with each other

Better food, hotter coffee, otherwise it was a very smooth and reasonably comfortable flight.

IFE didn't work. Wifi didn't work but they eventually managed to reset it. Our original flight was cancelled, so rebooked onto new flight seated apart from travel partner.
