Fair Food and Fair beverage... Air China indeed needs to have some western style food. seat is fair to poor condition; too narrow for me even for a economy class (mind you that business class is not much better). and maybe they should learn about something called "entertainment terminal". you stare at a public, plasma TV for 3 hours without change of programs. thanks for the ancient device. that does remind me what flights could be 20+ years ago.

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,
