You can use your earned travel rewards for a host of options. Some cards allow you to use your miles to cover the cost of previous travel-related expenses — including airfare, rental cars, hotel points, ride-sharing, and other charges. Or you can transfer them to frequent flyer miles. Miles cards usually provide more redemption options than just paying for flights. Co-branded airline mile cards allow you to use your miles to pay for flights, seat upgrades, in-flight purchases, and checked bags. Some may also offer free access to airport lounges, elite status with the airline’s loyalty program, gift card options, priority boarding, and other perks. You are likely to find plenty of travel rewards cards available whether you want all-inclusive travel miles, AAdvantage Miles, Chase Sapphire Ultimate Rewards points, Citi ThankYou Points, or perks through another rewards program. But before you hit submit on your online application, be sure that your earned rewards won’t expire if you don’t use them quickly. After all, saving up your rewards for a dream vacation is part of the fun of having a travel rewards credit card.
