The main purpose of this legislation, known as the "Rebuilding America's Airport Infrastructure Act," is to update and improve the passenger facility charge program managed by the Federal Aviation Administration (FAA). This program allows airports to collect fees from passengers to help fund airport improvements and infrastructure projects. Key provisions of the legislation include significant changes to the maximum amount airports can charge for passenger facility fees. Starting from January 1, 2027, the maximum fee will increase to $5.50.
