Foreign Transaction Fee when travelling?
 

I am thinking of using "AAdvantage® Aviator® Red World Elite Mastercard" by Barclays when I am in Europe. Card says
Foreign transaction fee: The AAdvantage Aviator Red World Elite Mastercard has a foreign transaction fee of 0% of each transaction in U.S. dollars.

There is still no foreign transaction fee right if I make purchases in Euro?

Costco Citi card is also free from Foreign Transaction Fee - I can use this as a fallback option?

Any popular cards people from US use in Europe?

Yes, both those cards are good for your trip, with no FTF.

Just make sure both are the modern versions of the card with contactless payment, so you can tap to pay, as that is the default now for most of Europe.
