I'm trying to choose which airline to fly to China on in November and Air Canada has some pretty good fares out of SEA via YVR (and 2 AC pilots I recently met left a really good impression). The flights I'm looking at are a 767 to PEK and a 340 out of HKG (I don't have the flight numbers on hand right now). I know they don't have PTV's, but that doesn't bug me (no box impeding on my legroom). How is their economy service? In general, how full are the flights? Is it a hassle to transit through Canada between China and the US? Can you tell me anything else?
Thanks in advance for any and all advice.
