AAAE's Transportation Security Clearinghouse is the only Designated Aviation Channeler with more than two decades of airport experience. The Clearinghouse is part of AAAE’s constant advocacy efforts on behalf of airports to ensure that airport interests, from the badging office and beyond, are represented at the federal level. That’s why the Clearinghouse remains proud to be the only DAC that answers to airports—not shareholders. Years after other channelers entered the marketplace, the Clearinghouse continues to remain the choice for hundreds of airports across the country.
