Yes, World of Hyatt points do expire, but the policy is quite generous compared to some other loyalty programs. Hyatt points will expire if your account remains inactive for 24 consecutive months. To keep your account "active" and prevent your points from being forfeited, you simply need to complete a "qualifying activity" at least once every two years. This includes earning points through a stay or eligible spend at a Hyatt property, redeeming points for a free night or room upgrade, or even transferring points from a partner like Chase Ultimate Rewards. Interestingly, holders of the World of Hyatt Credit Card are generally exempt from this expiration as long as the card remains active. If your account goes 23 months without activity, a small purchase of 1,000 points or a simple point transfer can reset the 24-month clock. However, once points have actually expired and been forfeited, Hyatt does not typically offer a way to reinstate them, so it is vital to monitor your "Account Activity" tab regularly.
