Service and the plane itself were terrific, but the extensive delays both before we left and after were a real pain.

Service and the plane itself were terrific, but the extensive delays both before we left and after were a real pain.

It was good and there is nothing to complain about .

The seats were narrower compare to other airlines traveling to Asia, which makes them uncomfortable after 6 hours The plane was worn, my tray table wasn’t level, You had to pay for WiFi and no Bluetooth option to use your own headphones. The crew was excellent in servicing the food and drinks. However I felt they needed some extra hands to serve the two sections of economy at the same time. They run out of one of the food option as they got to the rear section of the plane. Having travel on other Asian airlines during this trip; American Airlines can learn a bit from them, but I wonder if their service is geared towards a clientele that has become accustomed to not expect to much from an airline.

The crew was great, food was good. My concern is about the plane itself. It wasn't super clean, and during the landing process (after attendants had to take their seats) the air conditioning vent above my daughter's head started leaking a lot of water. It leaked for about 30 minutes, until we landed. I let the attendant know about the leak as we were getting off the plane, and she was very kind about saying she'd look into it. Given concerns about hygiene on planes, plus the fact that my daughter had to hold the blanket over her for 30 minutes to avoid getting soaked, that was not a great situation.

I paid for premium and it’s wasn’t what I was told I would be getting. Food wasn’t good. Should be able to pick and not be served items you dislike. Very little leg room.

I am trying to select a seat during booking but it respond that set assigment will be given during check in, and the seat assignment they give is in the middle seat and 2 row from the rest rooms, i am the person who pee a lot in this case I disturb so much the person beside me ,this trip is from Haneda to Texas, the trip from Texas to Cvg is a much better because its a smaller plane few passenger

Their in0flight movie selection is limited in size and poor in quality.

Japan airlines is a great airline. One of my favorites. The only issue I had was that I only pescatarian or I can eat vegetables, pasta, etc and both choices of meals were chicken or red meat. Most of other airlines have meat or pasta. Also usually I get an alert to order a meal prior to fly and this time I did not get one. Other than that everything was wonderful.

Boarding and crew service were excellent. Food was mediocre, not as good as our last trip four years ago.

Great level of comfort and highly professional and friendly flight crew. Keep up the great service.
