UK Amex (not BA) transfer rewards to US BAEC
I realize that it isn't possible to have a UK BA Amex and link it to a US BAEC account directly. However, is it possible to have a non-BA UK Amex, such as the traditional Gold/Platinum cards, and earn Membership Rewards with those, before transferring the points to a US BAEC account?
I searched but didn't find an answer to my specific question.
