On 11/29, the flight from Beijing to San Francisco was delayed because the incoming plane was late. All passengers were greeted at SFO with instructions for compensation. The instructions read "To claim the currency compensation, passengers must have a debit card issued in mainland China and marked with Union Pay!" If you are not a Chinese resident, you are out of luck!!! Americans be warned: Fly Air China and be treated a second class passengers!

The staff was extremely polite, very accommodating, and willing to serve. The entire experience was overall very good and very contrary to what reviews said online. I would fly with them again in a heartbeat, far exceeded American standard airlines like Delta and American.

Meals were decent, Staff was VERY attentive, courteous and polite. Ride was very smooth. Didn't hear much from the pilots, which is ok!

The no-phone, no-internet rule is absurd. I could have really used some internet-for-purchase on a 13 hour flight. Some movies were only in Chinese with no subtitles and the games seemed to require a separate controller with X/Y buttons. Overall blah score entertainment. Announcements were too frequent an intrusive, especially when they're repeating the same thing 2 minutes apart. Also, the weird rules--shades must be up during takeoff, but must be down while we were in the air. Seat must be up during meal time. Learn to chill a little China Air.

Crew was nice.

Just before boarding it was announced that there would be no hot water on board and passengers should try to run and get a coffee at the airport. 5 hour flight ahead. I didn't have free hand to carry a coffee on board.So no coffee or tea. Also no water in the bathrooms! All meals for purchase were not loaded so no veggies or any gluten free options for purchase. Wanted to buy Duty Free and was told that it wasn't loaded either for some reason. The cabin was a bit cool and after 4 hours of cold drinks I was a bit chilled and asked for a blanket only to discover that they only sell them to the passengers. Then I got the giggles as they thanked us for choosing Air Canada voted number one airline in North America. Hilarious!!!

The bathrooms were clean

First, our flight to Bali was canceled, there was a scam delaying and delaying the flight so that no one was offered vouchers. But the gate told us it was definitely canceled even though it was never officially canceled. We flew to Manila instead. They botched our return ticked accidentally booking us home on a flight 3 days later. We were on hold 45 minutes but no one answered when we tried to call so we had to wait at the airport to talk to someone - of course their convenient hours are 2AM - 10AM. When we finally did get a flight, the food was awful, the "vegetarian option" was inedible. The thimble of wine was mean considering there is no alcohol in flight. The snack was a tiny package containing 8 tasteless peanuts. We were reprimanded for getting more water. TERRIBLE!!!!!!!!!!!!!!!!!!!!!!!!!!!!

Lines to check in for boarding were LONG. One must arrive super early.

The airline did its job in getting me there alive and on time.

Not comfortable. Cant use phones at all. Crew wasn't very hospitable. Entertainment system wasn't fully functional. They make you close the shades no matter what time it is which takes away the perks of having a window seat.

Good food. Good service.

Crazy way ti aboard. A little disorganized and some people take advantage of that affective others. From the gate to the plane the bus made worst the situation. Some people disrespect others.

The flight attendants were very attentive. Not super friendly, but polite. And they gave me a vegetarian meal, which I really appreciated

They were VERY street about no cell phones or laptops even though I was on airplane mode. Plus, they even advertised wifi for the flight. On a 12 hour flight, I was mildly annoyed.

I paid 450 Euro for a return 2 hour flight & I didn't get a 20kg allowance. I don't expect a check in bag on a US or European budget airline but this is the national carrier. It's the first time I've paid for a checked bag in all my years flying with different national carriers. I.e. Qantas, Air New Zealand, Singapore to name a few. All in all. Air Canada charging like a national carrier but the baggage allowance policy of a budget airline. Not good enough in my opinion.

The attendant’s name is Karen. She first caught my attention was the way she talked to the passengers. She was like a parent or a teacher telling her kids to share but not solving their problem over the head bin. Then before we were landing, the passenger next to me asked for her help to put her bag into the head bin because she’s not tall enough. Karen said she’s doing security check and never came back. I managed to help my neighbor passenger before landing and was very impressed to this flight attendant.

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.
