Looks like we can add Barclays US Airways to this list after the emails that went out yesterday:
Goodbye Foreign Transaction Fees
Now you can enjoy purchases with no foreign transaction fees when you use your US Airways Dividend Miles® MasterCard® in Dublin, Paris, or Shanghai. In fact, no matter where you shop abroad, you'll enjoy this new benefit.

It's just a shame we don't yet know for sure whether this benefit will transfer to the AA Aviator Red cards that these cards are supposed to be transitioning to later this year. But here's hoping!
