MR (USA) to Aeroplan transfer "rejected"
A few days ago I transferred 200,000 MR points to Aeroplan. The points posted to Aeroplan instantly, which I used to book some flights. But today, I got a call from Amex saying that the transfer was rejected by Aeroplan and they are redepositing the points to my MR account. The Amex rep said it was the first time he'd ever heard of something like this, but everything on Amex's end looked fine and my MR balance includes the 200k points that I had transferred. I called Aeroplan after and they said there weren't any issues on their end either, and the flights I booked are all ticketed (I also double-checked the PNRs with the carriers and they are confirmed). So right now I magically have duplicate 200k points in both my MR and Aeroplan accounts (minus what I redeemed for flights).
Has anyone else experienced this problem? Will Amex eventually actually reverse the transfer (either taking the points back from Aeroplan, causing my account to go negative, or reducing my MR balance)?
