Clear allows you to skip the security line completely because instead of waiting in line, you approach a Clear kiosk where your ID and boarding pass are verified through biometric technology. Once that quick process is complete, a Clear agent escorts you right to the front of security.

The primary purpose of CLEAR is to expedite the identity verification stage of airport security by using biometrics instead of traditional physical ID documents. While TSA PreCheck focuses on the physical screening process (allowing you to keep your shoes and belt on), CLEAR is designed to "jump the line" at the document check station. Once you arrive at the airport, a CLEAR ambassador guides you to a dedicated kiosk where your identity is verified through an iris scan or fingerprints. This process replaces the need to wait for a TSA officer to manually inspect your driver's license or passport. After the biometric match, you are escorted directly to the front of the security screening line. In 2026, CLEAR+ has expanded its reach to dozens of major U.S. airports and sports stadiums, offering a predictable, high-tech solution for frequent travelers who want to minimize the variance of airport wait times. It is particularly effective when used in conjunction with TSA PreCheck, as it provides the fastest possible "curb-to-gate" experience currently available to the public.
