Despite somewhat limited English skills, the crew were very professional and pleasant. The flight was overall, a wuccess, and I would absolutely fly air china again.

The food on this leg of the trip was hit and miss. The food o. The first leg was very good. They have a ways to go to being their catering up to the level of some other airlines, he is been an overall positive experience.

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.

staff are overall friendly.

flights are delayed constantly, with connecting flights in short time span is impossible, luggage would miss and causes another delay

Flight was ok

The flight was actually run by turkish airlines, not philippine air as stated in my confirmation email, so we were sent to the wrong terminal. Nothing in the email said which terminal the flight would depart from or that it was actually turkish airlines. Very irresponsible and communication for customers should be much clearer. Luckily we were very early for the flight or it could have caused a serious problem.

I'm 6 ft 2. Legspace was adequate, and no silly boxes under the seats like other airlines that obstruct your feet. Great entertainment systems - modern, good selection. Food and staff excellent.

Their online checkin systems could operate a bit more smoothly. At one point, I had to go in in person, because the online checkin site had an already past flight from their codeshare partner SAS showing up as the next flight, and I couldn't perform online checkin as a result.

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.
