I'm traveling to Europe and need a Forex card. Which card offers the best combination of zero markup fees, reliable customer support, easy reloading, and airport lounge access? Any additional travel tips are welcome.

I love to travel, and mostly i travel through American Airlines. Looking over their credit card, i can't use points much much for anything outside their specific benefits. 
For travel related points collections, which is the best card? Or should i just use the American Airlines credit card?
