Whether your summer travel destination is domestic or international, the British Airways Credit Card is an attractive offer. It gives you enough bonus miles after your first purchase to score a free roundtrip transatlantic flight or up to three cross-country domestic flights, through a partnership with American Airlines. You can even double your gains by spending $20,000 on the card during the first year. That and the lack of foreign transaction fees are enough to make the $95 annual fee seem inconsequential.
