I just love it!!! For a non-refundable $85 fee (payable by money order, credit card, or a certified check) you can enroll in TSA PreCheck for five years.
TSA PreCheck is the expedited screening program that allows low-risk passengers to use a fast-tracked security line. In order to apply, you must be a U.S. citizen, a U.S. national, or a lawful permanent resident. The application process includes an in-person interview and background check.
