I have a Starwood Amex card, and a Blue Amex Card. I will be going overseas for a while to Europe for work, and since I will have a residence there I wanted to know if there are 'euro' based versions of these cards. I assume I pay a percentage fee for using my cards in Europe now when I travel (mostly to Brussels), for the exchange rate, and ideally I should get cards that are based on the euro and not the dollar. Anyone have experience here?

I have the same question for my American Airlines Citibank Mastercard (although I realise there is a separate forum for mastercard).

Thanks.
