I'm trying to book a flight but my Membership Rewards are currently frozen "for 6-12 weeks" as AMEX reviews my account to make sure all spend fits criteria. In retrospect I probably triggered it by trying to transfer MR around a month after opening a Gold card. In the meantime my father is willing to lend me the miles I need (transfer to his airline account and I'll book a ticket from there). My question is, when my account is unfrozen can I transfer MR points to my father if he is an AU on my card? I'm talking about transferring Membership Rewards points to his account, not partner airlines.
