BNParibas ATMs in Heathrow and Frankfurt airports?

You won't find BNP Paribas in London or Frankfurt airports, since it's a French bank. But you may find Barclay's Bank at Heathrow and Deutsche Bank in Frankfurt, both of which are under the same affiliation terms with B of A as BNP Paribas. As for exact locations....I doubt anyone could tell you an exact location, since you'll be in transit at two massive airports. We don't know what terminal or gate you're arriving at, whether you've got time to go out and back thru security again. If you want Euro cash before you arrive in downtown Paris, simply hit up the first bank ATM you see at Frankfurt or CDG and swallow the fee for your first transaction...then look for the BNP Paribas branches in Paris itself. Of course, avoid using ATMs at Heathrow, since all you'll get will be British pounds.
