I have around 16K on my Aeroplan account now. All those miles comes from flying SAS(dont worry I will be on several AC flights in August). I have a good experience with getting miles into my account. Only one time I had to mail in the tickets and boarding passes to Vancouver but that time it was me who forgot to put the Aeroplan number into the booking. Btw I never book tickets through an agent, I make all my bookings by myself.
