Called Aeroplan earlier today. Was on the phone for almost 3 hours but was able to swap all my flights and push my trip later this summer. Hopefully things get better by then.

Regarding reservations, I have a few flights with AC (YOW-YYZ-HND), but also a few with SQ. I am Silver Elite with SQ (therefore SA Silver) through status match while I have no Altitude level with AC. Is there any point in putting my Aeroplan number on my reservation versus my SQ number? I would assume that neither will accumulate mileage or segments but I guess in the event of someone being bumped it can help?
