I took the Eurostar a couple of weeks ago and while I was in the business lounge (courtesy of using my Amex Platinum card) I signed up for the Eurostar Frequent Traveller program.

Today I got a reject letter since I used my U.S. address. I could reapply using my French address, but I don't want to join if they are that strict. I really didn't see much benefit, but I join the programs by habit.

Is anyone else a member and is it really worth it?
