A CLEAR Plus membership is an annual subscription, meaning it lasts for 12 months from the date you are first charged. In 2026, the service continues to operate on an auto-renewal basis; unless you manually cancel your membership, it will automatically renew every year on your anniversary date. It is important to note that any "free trial" periods provided through partnerships (such as those with American Express or Delta) typically last for 2 to 4 months before converting into a paid annual plan. If you cancel your membership more than 14 days after a charge, you will usually retain access to the CLEAR Plus lanes until the end of your current 12-month term, at which point your account will downgrade to a "Basic" (free) membership, which no longer provides the expedited biometric airport security benefits.
