Currently based in southeast China, I will be flying back to Canada (probably through Hong Kong) at least 5 times in 2010, flying to Vancouver, Calgary, Toronto and Montreal. As I will be flying business each time on company expense, I am pretty sure this will get me Air Canada Super Elite.

Going through Hong Kong, am I better off doing everything on Air Canada or am I better doing transpacific on Cathay Pacific and the rest on Air Canada (which will get me Cathay Gold/oneWorld Sapphire and probably Air Canada Elite/Star Alliance Gold)? Or is there another airline that would be better?

My major qualm with doing everything on Air Canada is availability of reward flights (there is never any availability in Executive First out of Hong Kong) and the stiff fuel tariffs. However, the tradeoff I guess is the SWU and SSWU certificates, although I am not sure about the availability of those out of Hong Kong either.
