Chase Platinum-No Foreign Xch. Fee
I can't find the thread but there were questions about whether Chase was true in saying they did not charge a fee add-on to foreign currency charges (e.g. charges overseas).
I just spent a month in Paris and used my Chase Platinum MC extensively. I usually use Firstcard to get UAL miles but they announced the 3% fee add-on (now delayed?) so I switched to Chase.
I've gone through all my charges and there's no fee add-on I can find. The exchange rate for francs/dollars in the Wall St. Journal was $6.05-$6.13 while I was there and I got $6.06-$6.14, a little better. I can't even find the 1% add-on that Visa and MC are supposed to charge before it gets to the issuing bank.
Chase is keeping its word on this and I suggest you consider using them, if their miles connections work for you.
