I am happy to report that the time to transfer points to Flying Club is substantially less than the 5 business days quoted by Amex.
I registered my Flying Club account with Amex online on Friday midnight and did a transfer straight away while the registration was still showing as pending. The points were already in my account on Monday evening.![Big Grin :D :D](data:image/gif;base64,R0lGODlhAQABAIAAAAAAAP///yH5BAEAAAAALAAAAAABAAEAAAIBRAA7)
