SEC. 103. LIMITATION; PRECHECK OPERATIONS MAINTAINED; ALTERNATE METHODS.
(a) In General.—Except as provided in subsection (c), the Administrator shall direct that access to expedited airport security screening at an airport security checkpoint be limited to only the following:

(1) A passenger who voluntarily submits biographic and biometric information for a security risk assessment and whose application for the PreCheck program has been approved, or a passenger who is a participant in another trusted or registered traveler program of the Department.

(2) A passenger traveling pursuant to section 44903 of title 49, United States Code (as established under the Risk-Based Security for Members of the Armed Forces Act (Public Law 112–86)), section 44927 of such title (as established under the Helping Heroes Fly Act (Public Law 113–27)), or section 44928 of such title (as established under the Honor Flight Act (Public Law 113–221)).

(3) A passenger who did not voluntarily submit biographic and biometric information for a security risk assessment but is a member of a population designated by the Administrator as known and low-risk and who may be issued a unique, known traveler number by the Administrator determining that such passenger is a member of a category of travelers designated by the Administrator as known and low-risk.

(b) PreCheck Operations Maintained.—In carrying out subsection (a), the Administrator shall ensure that expedited airport security screening remains available to passengers at or above the level that exists on the day before the date of the enactment of this Act.

(c) Frequent Fliers.—If the Administrator determines that such is appropriate, the implementation of subsection (a) may be delayed by up to 1 year with respect to the population of passengers who did not voluntarily submit biographic and biometric information for security risk assessments but who nevertheless receive expedited airport security screening because such passengers are designated as frequent fliers by air carriers. If the Administrator uses the authority provided by this subsection, the Administrator shall notify the Committee on Homeland Security of the House of Representatives and the Committee on Homeland Security and Governmental Affairs and the Committee on Commerce, Science, and Transportation of the Senate of such phased-in implementation.
