While high cashback rates are a valuable feature in many credit cards, they are not the defining benefit of most travel rewards cards. Cashback cards are usually more focused on everyday spending categories like groceries or gas. Travel rewards cards, on the other hand, offer value through points or miles that can be redeemed for flights, hotels, or other travel expenses. If your goal is to earn free trips and maximize travel perks, you'll want a card that offers travel-specific benefits—not just cashback on purchases.
