The American Airlines AAdvantage® MileUp® Card is great for AA travelers on a budget who frequently shop for groceries. This card lets you earn double the miles in supermarkets and on American Airlines purchases, plus 15,000 bonus miles after spending $500 in the first three months.
However, the AA MileUp card charges a 3% foreign transaction fee. If you are using the card while traveling, you might find the Citi AAdvantage Platinum Select World Elite Mastercard more rewarding despite the $99 annual fee (and the long, complex name).
