Back in 2000 or 2001, I once was upgraded on AS from SEA-YVR when I mis-connected my original Dash-8 flight and was put on the lone 737 flight to YVR. I asked at the AS transfer desk if elites could be upgraded and since my original CO EWR-SEA leg was upgraded using miles, could I get first. She said it was not AS policy, but she would give it to me anyway because of blahblity-blah...so basically, it's a no but it never HURTS to ask...
