I read an article online that said you can transfer Amex points to Eurostar's loyalty program (and the rates appear to be quite attractive). I have tried doing the transfer at the below link: https://www.americanexpress.com/en-g...ub-Eurostar/ES

However the website keeps erroring out, saying it can't load. I'm guessing the issue is I need a UK MR account and I do not. Does anyone know if there's a way to get points into Club Eurostar from a US based MR account? Thanks.
