You're probably right. That might be the one thing that keeps me collecting Aeroplan points in hopes that I can save up enough for one last redemption.

I'd be pretty annoyed if I couldn't use the 600K that I have right now the way that I've planned, but for anything I collect from here on in... well, I'll consider myself lucky if I can actually redeem for flights. I do not intend to carry anything over past the 2020 end date.
