The flight waited which I'm sure is a complaint by others. This is due to the very inefficient transfer process in Beijing.

Zero entertainment. I know it's only a 4-5 hour flight but still.

They upgraded my wife and I to an Exit Row, I'm tall

Dirty bathrooms, overall poor sanitary conditions of plane. Once in Beijing we had to go thru Immigration and Security again even though we were just transferring to another international destination (Bangkok) and the lines for both Immigration and Security in Beijing were super long and grossly understaffed. Even with a 2 hour layover we almost missed our connecting flight to Bangkok.

Most of the staff was very helpful and accommodating. On the first leg of the flight one of the attendants even suggested a wine with dinner, a very kind gesture.

When my husband and I went to check in for our flight at the desk we had to wait very long time to get checked in. We noticed that one of the girls was in training, which is understandable but just inconvenient. We are both very patient people but this just made us nervous because our first flight on Air China to Japan on 10/26/17 was very delayed and caused us to have to literally run and still go through a rigorous security check. We were not rushed through the line even though we had nothing to do with our flight being delayed on our second leg. We then had to wait in another long line for security even after arriving into China on our flight back. There was also someone on board before take off with a medical problem and we could tell that some of the patrons started getting a bit aggressive or irritable. I don’t think the crew could’ve done much in that regard but wish the issue had been resolved a little quicker. I believe it was a 40 minute delay in take off.

Doesn't matter if your economy or first class. First one to the gate gets in. Good for me because I always fly economy.

Typical Chinese service, poor. Will never fly Air China ever again. Only reason why I book the ticket because it was cheap, now I know why.

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.
