Decent flight, staff was very good, especially with the turbulence during the flight due to weather. Comfort was about par with other airlines but since it was a quick flight, was not much of an issue for us.

Great flight, although I flew out of ONT and that is where my car is, lol
Better training to have qualified crews and services. My flight was from around 12 midnight Friday Taipei to Vancouver. After two hours first meal (2:00 Am -8:00 ) no crew available for even asking for some water. I was even willing to pay for water. For breakfast after 8 hours the only drink was tea and coffee no water or juice.
3 of the 4 flights had delays despite the weather being fine, but still managed to make all connections
Ask flight attendant for water during flight and she was a little rude get the water.
Flight was delay almost 2 hours from Hong Kong to Taipei. Last minute gate change from 24 to 66. Long way walk. We need to run in the Taipei airport to catch our next flight from Taipei to Vancouver. That is so suck!
For a long-haul flight, the crew did a very good job of keeping the lavatories clean and the aisles clear.
The check-in crew at SF did not put on breakable glass stickers on check-in baggages which caused my antique whisky bottle to break during transportation.
My BIG complaint was that my second flight was also delayed. That's very aggravating after traveling for 18 hours already.
Lovely service and excellent food and entertainment! I couldn’t have been more happy flying with air China
