It depends on how often you use your card and whether you like to travel regularly. If you're a frequent credit card user and you choose a card with a high points earning rate, you'll build a points balance quickly and be able to access a wide range of travel-related rewards. However, you'll also need to factor in the card's annual fee, plus make sure to pay your card off during the interest-free grace period, to decide whether a travel rewards credit card is worth it.
