The flight crew was outstanding. Very cheerful and always respectful. I wish the same could be said about United. The AC wasn't the best on the plane.

The flight crew was outstanding. Very cheerful and always respectful. I wish the same could be said about United. The AC wasn't the best on the plane.

The seats are uncomfortable. The flight attendants are not pleasant. They do their job, but not with a ray of sunshine and warmth. The food was awful, not what I would expect from an Asian airline. All of the other Asian airlines I have flown have far better food. The food was on par with United airlines food, which is really bad. Maybe ANA should get out of the alliance with United.

During booking, I selected the seats so that my wife and I would sit next to each other. However, the airline changed our seats at boarding so that we were seated apart. Very disappointing.

Every leg of the flight was late causing us to miss our flight to Okinawa and have to take the next flight out.

One of the best 14 hour flights I've ever had. Crew was friendly throughout which can be difficult on longer flights. The crew being kind and respectful is very important for me. Plane felt clean and I was able to get some well needed uninterrupted sleep. I put them slightly above Cathay Pacific as far as cleanliness the only down side was a lack of entertainment selections, but hey I am an American taking a trip on a Japanese airline so I cannot complain. Thank you ANA and the Tokyo airport all very friendly. Will see you soon

ANA gave me an amazing experience. They are very good with customer service.

Everything was good may improve some alcohol drinks and amenities during fly

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.

highly recommend for trip to japan only reason why i gave good not excellent is because their selection of movies and tv shows in English is more limited .

We asked for Hindu vegetarian meal in advance and the quality of the food was horrendous. Never flying JAL again!

Japan airline is excellent service .I recommend to Kayak and Japan airline to Frend.

Overall a great experience. One complain was the vegetarian food that my wife had which was mostly boiled vegetables with not much flavor.

Very accommodating and kind airline crews. The plane is also big which makes the passengers more comfortable and relax

I actually didn’t make it onto the flight. I spent quite a few hours trying to rebook the flight just to get screwed out of $5000. Fun!

We booked business class round trip from Delhi to San Diego and back. On our last leg from Bangalore to Delhi we were down graded to economy class which was big disappointment other than that everything was great.

Had an incident with a stewardess who insisted that I take a seat. I informed her that I came to use the restroom and to have some water. After using the restroom, I wanted to stretch my legs out a little cuz my knees were aching from sitting. I understood her concern for my concern and the potential turbulence (she said she knows this route and the turbulence and safety is not to be taken lightly) but I felt that her mood, tone, demeanor, and a lack of compassion for the pain in my knees were not the proper way to address a customer or anyone for that matter. This left a bitter taste in my mouth. It was her lack of professionalism that surprised me.

we have requested for hindu veg. meal during booking. but served meal was of very poor qualty and taste. they can get such meal from 5 star Indian restaurant at Vancouver/ tokyo/ Bangalore.pure hindu veg meal and no AVML

It was good but need mor amenities for toiletries and entertainment
