I have an aeroplan award miles itinerary beginning on Sat morning. My award ticket is all business except for the first segment (YVR-YYC). Upon booking this itinerary I was told that there was currently no available business class seating for this segment, however the agent did put a note on my account for me to be upgraded should room open up. My question is as follows: Does the manner in which I check-in (web,blackberry, in person @ yvr) affect my ability to be upgraded or this simply something that will happen last minute @ the gate and check-in method is a moot point here?

Thanks in advance
