Points accrued as a World of Hyatt cardholder won't expire as long as you keep the account open. To maintain an open account, there needs to be activity on your card at least once every 24 months. If your card is inactive for 24 consecutive months, you'll lose any unredeemed points. While your points will be forfeited, the good news is your account remains open. You can remain active in the rewards program for your card in a number of ways: by earning points, receiving points through a partner program, redeeming points, gifting a program award, converting your points through Partner Program awards, or purchasing or combining points.
