A travel rewards credit card that is not connected with any airline will be a good option for you. For example, it can be the Discover it® Miles. The card has no annual fee, no foreign transaction fee and it has a 0% intro APR on purchases (when the introductory interest rate is over, the ongoing APR will apply). Your ongoing interest rate will be determined by Discover based on your creditworthiness. The Discover it® Miles card allows to earn miles rewards on all purchases. Currently, every dollar you spend on purchases will earn 1.5 miles. First-year miles will be matched at the end of your first year cardmembership – that is, you will get double the miles for the first year. There is no limit to how many miles you can earn and miles do not expire. Earned miles can be redeemed for any airfare. Just buy your airline ticket using the Discover it® Miles card, and then apply your miles to the purchase.
