Weekends are for maintenance. Has anyone tried to make a transfer by phone?
I cannot recall that American Express ever removed a transfer partner without notice. Look back at the threads announcing that CO and WN were leaving. We knew months in advance. Many other partners disappear from the website for a few days, and then reappear.
I agree in theory (and hope so), however it may have come from the other end, especially since AP is owned by a 3rd party
