I have nearly 50000 Amex reward points but am about to close that card account. I would like to transfer these to Aeroplan but on the Amex site this isn't possible directly. However it appears that the Amex points could be transferred to Singapore's KrisFlyer n a 1:1 basis and KrisFlyer points can be transferred to Aeroplan again 1:1. Does anyone have experience of this or any other way to transfer Amex to Aeroplan?
