Extremely poor at handling baggage. I had oversized golf bag and JAL would not recheck in Boston. Had to haul by myself to Jet Blue. Both JAL and Jet Blue claimed I had overweight bag. Had to adjust baggage several times. Will avoid JAL in future and I always avoid Jet Blue when I can. QATAR always superior.

Had to adjust baggage several times. Will avoid JAL in future and I always avoid Jet Blue when I can. QATAR always superior.

JAL using the state of art A350-1000 for JFK to HND It’s a great plane to fly Very comfortable with lower cabin altitude Quieter cabin Wider seats Big tv screen Excellent service and catering

I fly to Asia twice a year for the last 15 years. I always try to fly JAL. It’s always a pleasant experience. Since TripCase shut down, this is the first time I used Kayak for live trip notifications. I was very pleased with Kayak’s quality and helpfulness of notifications. I will be using them going forward.

This flight was leg 2 of 2 leg journey. The staff at baggage re-drop in Tokyo were fabulous. Once at gate when time to board, had to take standing room bus to the tarmac to board. Did not like getting out to plane and having to wait 5 minutes until they opened bus door.

First experience with JAL so was okay to pretty good. 10 hour flight in premium select seat. . Seats in that category should be better than pretty good. Seat pan a little short for tall people but plenty of leg room; I think JAL in process of new planes? Also, — they could have offered a bit more water throughout flight and meals not the greatest. That said, certainly 200 percent better than a very recent AK Air International flight in similar cabin class in comfort and meals.

It's a domestic flight, but still the JAL quality shone through. The crew were polite and helpful and even prepared little gifts / souvenirs for the children on the flight, and everyone got a simple drink. The free wifi for entertainment on the personal device was also a great boon, and the shows surprisingly decent. Would recommend.

We ordered for non vegetarian Hindu meal but instead they served us vegetarian Hindu meal. That was also not good. It was very annoying and aggravating. Hope our return from Tokyo to jfk on March 27 same is not repeated. Caterar should understand difference between non vegetarian Hindu meal and vegetarian Hindu meal.

Allow gold card holders (Group 1) to board with their guest like other One World carriers do

Checked baggage process is confusing and time consuming especially when checking oversized bags. Very slow agents didn't help.

Food was great, Entertainment was bad, movies were not current and just did not have good variety. Granted I was tired so cranky might have played into my evaluation. Overall based on cost I definitely would fly them again. I am a million mile flyer on another airline, the service on JAL really beats all airlines.

Due to turbulence there was no inflight service, which is very understandable, The flight is very short, and safety is more important. There was a bit of a delay with take off, but was to be expected with the rain.

The crew was amazing, really friendly and efficient. One of the best flights I have ever been on. They made the long flight comfortable and I noticed there were two birthdays on the flight. They gave to customers birthday cards and wished them a happy birthday. That was very nice to see.

Everything was great. Wifi was down,but that didn't matter to me.

The staff are very kind ,friendly and helpful .This is my first time flying with ANA and surely will fly again.

The best best best flight experience I have ever had. And I fly A LOT. THANK YOU, ANA!!!

My wife and I liked almost everything about ANA except for the economy seat space and the cold breakfast (croissant which seemed to just come out of the fridge)

Excellent service and comfortable seats. Friendly and helpful staff. No food for a 3hr flight over lunch time which was surprising (or is that a feature of domestic flights in Japan?)

When booking the flight i picked it because it said flying with ana even on our e-ticket as well but I showed up to the airport and I flew with united. I have flew with both airlines before and I prefer ana for the food quality and comfortable. So I was disappointed in that outcome and felt the food gave me minor ibs. The whole thing was missing leading with not getting what I thought I was paying for. Felt a bait and switched. Do not have confidence in using this app in the future trips

This was a large plane with an upper deck. It seems like business was upstairs. If it was a US airline then I would say I sat in economy plus, but I think it was just economy. Though since ANA would not allow me to choose seats for the price it may have been plus. Lots of movies to choose from, and good service.

This was the best airline I’ve ever taken. The staff are amazing. The food was great. The pilot was phenomenal. I would highly recommend this airline.
