I am commuting between the SFO and Canada every week and am considering buying one of the Air Canada "Flight Credits" Flight Passes (as opposed to unlimited travel for 3 or 6 months) to save some money. While the Flight Pass program has to be managed using an Aeroplan account, I was wondering if the FFN can be changed to UA at time of online check-in, and if so, whether miles/EQMs are actually credited to UA MP. Has anybody had experience with AC's Flight Passes before and tried to credit miles to a non-Aeroplan account?
