Your travel on Government aircraft will not be reported unless you are a senior Federal official, or a non-Federal traveler. (Travel under 10 U.S.C. 2648 is not reported.) If you are a senior Federal official or a non-Federal traveler, any use you make of Government aircraft, i.e., as a passenger, crewmember, or qualified non-crewmember, will be reported to the General Services Administration (GSA) by the agency that owns or hires the Government aircraft. (Agencies must maintain information on classified trips, but do not report classified trips to GSA.)
