Just made a sizable transfer AMEX US to AsiaMiles and it happened instantly to my surprise. The ticketing agent even called me back when he noticed my balance had increased (which was another shock after several 2-hour hold phone calls to CX to sort it out).

Today is my second AMEX transfer to AsiaMiles, so perhaps what [MENTION=874767]Cambo[/MENTION] said above is true about subsequent transfer. My first AMEX to AsiaMiles transfer in August tool just over 3 full days.

For those of you anticipating a large transfer in the future, consider transferring 1k points initially to clear the initial transfer. Perhaps subsequent transfers will happen more instant?
