Amex had previously frozen many Membership Rewards accounts for people who had applied and were approved for the recent 100K bonus offer on the American Express Platinum card. Cards were working fine but MR points connected to the cards couldn’t be used to transfer to travel partners. The scary part was that all MR points were frozen, nut just those earned through the Platinum card.
This offer was apparently a glitch. It was meant as a targeted offer that somehow went public and I’m guessing way too many people jumped on it and so did I.
Well, the good news is that everything is back to normal. You can now transfer your MR points to travel partners without any issues. I tested it out myself by transferring 250 MR points to BA and… success!
