You can choose any general rewards card from travel rewards credit cards with miles or points rewards. It is better to choose a card with rewards on all purchases and flexible redemption options. For example, you may like the Discover it® Miles credit card. It is a no annual fee credit card that will allow you to earn miles on all credit card purchases. The card also has a promo offer for new cardmembers. All miles that are earned within the first year of cardmembership will be matched at the end of the first year. There are no caps to how many miles you can earn, so basically, you bonus can be as big as you wish.
