Crew service was excellent. Food choice and spread was nice and I was able to eat well despite not eating the chinese dishes.

I wish the food was american chinese - like PF chang !

The food was gross. The look and smell of it all was enough to make me just go hungry for the 5 hour flight. Airplane food is not for me.

Okay 5.3

Scored an awesome seat with no one next to me in a small cabin between first and coach class.

Even after I had carefully check luggage restrictions I got thoroughly hassled about my ski bag and had to pay considerably extra and do major persuading. The fact the air china desk doesn't open till within 3 hours of flight time at Tom Bradley international terminal at lax is madness. All these red eye flights going through security at once was one of my worst flight experiences. I the picture I took of it is an awesome representation of the term madness

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.
