Food was good. Flight attendants were good.

Tiny beds in business class with two-across seating so the window passenger has to climb over the aisle passenger. Are they stuck in the 90s? I won't fly with them again. Boarding in Beijing for Manila was a free for all. Business class was not called first. Isn't this why I pay triple the coach fare? No English language newspapers from Los Angeles to Beijing.

I am incredibly happy with my Air China experience. Crew worked diligently to create a good experience, and was kind when I was having difficulty communicating. The food was surprisingly fabulous! Authentic Chinese cuisine and tasty. Several passengers did not review the regulations and were pretty rude when Air China crew told them to turn off and put away cell phones. Crew handled this well.

Bathrooms were not very clean. I didn't realize until halfway through the flight that we needed to get our own beverages and throw away our own trash (different than the other airlines)- would have appreciated this being announced. I was confused during boarding process about when to stand and when to board, but watched the people around me and figured it out. We took off late/ landed late, but I was able to make my connection in Beijing without any stress so was happy.

Premium comfort seats are worth it especially on longer flights; totally recommend. Plum wine is a great add to menu

You need to call to reserve seat. Then was told I could only upgrade at the airport and not on the phone, risking to loose the few available premium comfort seats. Old movies. Poor red wine. Food still just okay.

Our flight was delayed for two hours. We have a connecting flight from Osaka to Los Angeles, which we were worried we couldn't make it. They told me the flight will wait for us because there were 20 plus people also need to get on that plane. When the time of boarding we heard they were calling us to the front and explained the flight we were suppose to be connecting already took off. They had to booked us to another airline. We were extremely disappointed! We asked if we could took another Japanese airline but they said our luggages were already transferred to that airline and the tickets were printed! Mosf importantly we have already waited in airport 5 hours and they needed us to wait for another 3 hours! Very bad experience with how they dealing with this situation!

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.
