Can TSA PreCheck® benefits be used for both official and personal travel?

Yes. Members of the U.S. Armed Forces and DOD Federal civilians can use TSA PreCheck® benefits for both official and personal travel. Be sure to update all travel reservations with your DOD ID number listed as the Known Traveler Number (KTN)  to enjoy benefits. The KTN also can be added when booking reservations online via a participating airline website, by phone with an airline reservation agent or with the travel management company making reservations. Save your KTN to any frequent flyer profiles, employer booking systems or online travel websites that you use.
