What you have to go through in Beijing to transit from one international flight to another. Very disorganized. I will never change planes again in Beijing after this trip. Perhaps it will be better on the way back. Business class travelers should have a special lane.

Compared to the flight going the other way, this one was much more comfortable. I didn't have someone's seat back in my face the whole time, and was able to enjoy games on my own device. I like that both USB and normal power options were available, so I was able to play games and charge my phone so I could use it after landing. The food was passable as well, which was surprising.

It's unavoidable when flying between multi-lingual locations, but having movies and stuff pause three times for each announcement gets annoying. The rolls served with the meals were very dry. These are small nits, and the flight was generally enjoyable.

Where do i start? It’s a short flight to be sure but air canada planes never feel like many Other airlines’ mini planes or puddle jumpers. they seem new, spacious, seat back Entertainemnt, just great. Also, there is no scrimping on Service. How many Delta or united or American flights have i taken on this route only to be told “coffee or water” and sometimes no coffee “the flight is too short”. Nonsense! Granted I was in business, but I had a full hot breakfast served and a full array of beverages offered. It AC can do it, everyone can. The flight attendant was lovely.

The flight was too short :)

The crew, the flight, the pilot to cabin communications, the food, and the movie selection was amazing. I am so happy that I flew Japan Airlines on my return trip. I would highly recommend them for your travels.

A Japan Airlines employee escorted me every step of the way to ensure that I made my connecting flight from Tokyo to San Diego because I only had an hour and ten minute layover and this can be challenging when you’re in a foreign country. I cannot thank Japan Airlines enough for how easy they made traveling and how comfortable they made me feel. I Highly recommend flying Japan Airlines for your travels.

Great leg room and wonderful flight staff. Coffee was excellent.

Movie selection too limited and the same movies were offered on the return flight. The smell of sesame oil was a bit overpowering on the flight due to food choices offered. Additionally, an American/European style breakfast option would have been nice. We were offered two meals on our 14 hour overnight flight and both consisted of what we would consider to be dinner or lunch options.

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.

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.
