Travel rewards credit cards are financial products that allow users to earn points or miles for every dollar spent. These rewards can be redeemed for various travel-related expenses, such as flights, hotel stays, and car rentals. Many cards also offer sign-up bonuses, which can significantly boost your rewards balance when you meet a minimum spending requirement. In addition to earning rewards, travel rewards credit cards often come with perks like travel insurance, no foreign transaction fees, and access to airport lounges. Popular options include cards from Chase, American Express, and Capital One, each offering unique benefits tailored to different travel preferences.
