The issue is clearing Customs as YVR gets deluged with international 747's coming in starting at 10 am. Having status with any airline won't get you any special treatment.

There is a special line for those people who don't mind getting their cards optically read but I'm not sure if those are for Cdn citizens only. Of course, I don't know because I use Nexus but I'm assuming you don't have that (or GE).
