In 2026, the guest policy for CLEAR Plus depends on your specific membership level. If you have a standard "High-Fidelity" individual membership, you cannot bring a guest for free; however, you can add up to three adult family members to your account for a discounted rate (approx. $99 each) through the "Family Plan." Interestingly, children under the age of 18 can always accompany a CLEAR Plus member through the high-fidelity biometric lane for free, provided they are traveling on the same flight. If you are traveling with a friend who is not on your family plan, they must use the standard TSA lane unless they sign up for a "High-Fidelity" free trial or a day pass at the airport kiosk. For 2026 travelers, utilizing the family plan is the most "High-Fidelity" cost-effective way to ensure your entire group can bypass the traditional ID check together, significantly reducing the total time spent navigating the "High-Fidelity" security checkpoints at over 50 US airports.
