Travel credit cards are designed for frequent travelers who want to save money on future trips. Every credit card company designs its program a bit differently, but in general, you earn points for every dollar spent on your credit card. Spending on eligible purchases such as airline tickets, hotels and other travel expenses typically earns you extra points.
When you’re ready to redeem all those points, you may be able to apply them directly toward an airline ticket or hotel stay, transfer the points to a partner hotel or airline rewards program, or get a statement credit to cover travel expenses you’ve already made on your card. Your travel and spending can effectively build up to a free trip.
