A couple of updates on my recent cancellations.

I got a refund notice on May 10th for a booking that I cancelled April 10th. The money showed up on my credit card yesterday (May 12th), dated May 11th.

My infamous February 24th cancellation, still nothing from Aeroplan/AC, and my CC issuer hadn't even posted the temporary credit yet. I phoned Aeroplan again today, and after previously being told it was "in the queue" and I just needed to wait, I explained to the guy that it had now been 80 days since I cancelled it, and that yesterday I had received a refund for a booking cancelled only 30 days before, so I wasn't waiting around anymore. Surprisingly, he put me on hold to talk to ticketing and got it done in about 5 minutes, with refund notices sent by e-mail for both tickets (2 tickets, 1 PNR). Hopefully the funds will show up quickly on my credit card again and I can finally have my damned $287.30 back.
