Responders: right you are. I, for example, have an Aeroplan account and a CIBC Aerogold credit card. Today, as a matter of fact, I registered with Future Shop to enhance my point building potential.
Empress is dead on saying that having these points are a great backup to standby travel for us. I'll do anything to avoid (God forbid) actually having to buy a ticket. How I get from A to B is not a priority; just that fact that I can.
