Good land side service (partially because I am Star Gold) and fair on-board service. luggage was delivered faster than expected in beijing.

Fair Food and Fair beverage... Air China indeed needs to have some western style food. seat is fair to poor condition; too narrow for me even for a economy class (mind you that business class is not much better). and maybe they should learn about something called "entertainment terminal". you stare at a public, plasma TV for 3 hours without change of programs. thanks for the ancient device. that does remind me what flights could be 20+ years ago.

I was stranded by not being aloud to board the plane there was a visa problem at my destination the air China staff required me to have a visa to enter the country of India. There is a tourist visa for under 180 days stay. That’s what I get when I enter on a land route just a 60 day visa upon arrival so the agents would not let me board. Air China sent me a note that I could cancel the flight and should be able to get a refund. I have called 6 times already and have yet to speak with anyone I stayed in the station all night and at 9 am today they will give be a number that will work

I would like to get a full refund

Plane was new and very comfortable. Smooth flight

Flight attendants had to serve food/drinks, which they did the entire flight (literally, drink service took 2 hours). People got drunk and super loud. We were late leaving London which isn’t an issue except the people at the BA desk were the least helpful. We found out more from the pilots than anyone in the airport.

Nice crew

A few peoples televisions, including my own, just stopped working midway through the flight. The crew didn't offer us much to drink (like they didn't walk around offering water enough). Also paid extra for seating which we did not get the seats I paid for pretty sure.

Late BA flight made sure I had to wait 7 hours to catch and EVA air flight. I want my money back. I paid 1000 to flight British Airways not to be crammed on a flight as a show away. Super uncomfortable seat on EVA and a terrible experience. I fell on the plane.

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.
