Configuration of your 787-800 Busn./ Class,was nothing more than an updated 707 from the past. Crew was good food was average. A flight I may avoid.

The configuration of 787-900 Busn. Class was very good. However need to age Chivas Regal to 18 years like KAL, not ordinary 12 years. Flight attendants were exceptionally efficient, professional, courteous, and outstanding ambassadors for ANA and Japan itself. In the US Marine Corps we would say "Ooo Rah". I may heed to check out your milage club and stop using various carriers for my trans Pacific flights. Thank you very much ANA.

I liked that they provided blankets and complimentary drinks.

They didn’t provide entertainment properly, you needed to have the United app downloaded ahead of time if you wanted to see any movies. All food was made for purchase they did not offer any free food.

Okay 5.3

Flight was on time, smooth with efficient boarding and quick baggage retrieval.

Only one beverage service shortly after takeoff. No additional offers of drink or snack on 6 hour flight. Attendants were sitting around in rear galley. One was knitting! I told them that trash receptacle was full in restroom. The response was "I'll put on gloves and "push it down" but it was still unusable fifteen minutes later. Had to pay $7.99 to access flight map. No earbuds were offered. Attendants were invisible except for collecting trash.

Okay 5.3

There was a fair amount of leg room.

Boarding could be a little frustrating because groups 3 4 5 were 1 lane and there wasn't a lot of room in the airport. Also, there wasn't a lot of time to get from one side of the airport to the other to stop at the restroom and get a real meal, since there was nothing served on the previous flight. Due to turbulence there was nothing served on the flight, which is beyond the control of the crew. They knrw ahead of time about the turbulence, perhaps they could have quickly passed out pretzels or cookie before the flight took off.

Very nice flight attendant and the landing was very smooth.

I’m not a fan of the waffle cookies, wish they had a couple of choices of snacks.

Prices are per person and are for e–tickets and include all taxes & fees in USD.

We attempt to get accurate prices, however, prices are not guaranteed.

Here's why:

We’re not the seller.
At KAYAK we don’t set the prices, so it’s not possible for us to guarantee what other companies are selling.

We compile tonnes of data for you
Our service lets you quickly and easily compare results from hundreds of travel sites at once. In this sense, KAYAK is a search engine and we can't guarantee prices we find.

Why aren’t prices accurate 100% of the time?
Prices on airline seats, hotel rooms and car rentals can change frequently. Several people may also be trying to buy the same travel option simultaneously. As a result, you may find, on occasion, that certain prices are no longer available.

If you have more questions or if you have a bad price to report to us,
please send us an and someone from our team will get back to you promptly.
