My attempt to link my Aeroplan account has been stuck on "transfer in progress" for 48 hours now (this is just linking, not transferring actual points). Amex customer support, after 3 hours, has not been able to help, and instead cited that their Aeroplan liason says the servers are having issues.
My LH F seats I wanted have already disappeared.
Does anyone know what is going on / has had a similar issue?
