You must report on a semi-annual basis to the General Services Administration (GSA) information about Senior Federal officials and non-Federal travelers who fly aboard your aircraft. The reporting periods are October 1 through March 31 and April 1 through September 30 of each fiscal year. A report is due to GSA not later than 30 calendar days after the close of each reporting period and must contain the following information:
41 C.F.R. §301-70.907
You are not required to report classified trips; however, you must maintain information on classified trips for two years. Most of the information required by paragraphs (a) through (g) of this section can be found on the traveler's travel authorization. Your aircraft management office must provide the information about crewmembers and qualified non-crewmembers required by paragraph (b) as well as the information required by paragraph (h). For more information on calculating costs, see the "U.S. Government Aircraft Cost Accounting Guide," published by the General Services Administration, Office of Government-wide Policy.
