The key to choosing a travel rewards credit card is to figure out what your goal is: Do you want to earn free flights on a specific airline? Do you travel a lot and want to get cash back for those purchases? Or do you just want to earn rewards to spend on travel purchases? Once you determine what you want from a credit card, considering your spending habits will help you select the card that's most beneficial for you.
