I'm an AC Aeroplan member, considering switching programs so this is interesting information for me. AC awards are all capacity controlled and there is no option to pay additional miles if they're gone. What class do the *A awards come from? I can book a North America reward flight on UA for 25/40/60 Aeroplan miles, or to Western Europe for 60/80/100 - how do these points compare to the standard award levels on UA?
