This was helpful information. I just spoke to the MR department at AmEx UK and was told that I could open a new US AmEx account, and that once per year I could request an international transfer of MR points from my UK MR account to the US MR account.

Of course, I would have to pay the fee to have a US Platinum in addition to the fee I now pay for a UK IDC Platinum, but it is certainly an option in order to get my points into a *A carrier.

Not sure if I should accept the UK Centurion invitation and hope I could somehow get it transferred to a US Centurion, but it is food for thought.

Thanks for all the advice!
