DoD Instruction 5154.31

DoDI 5154.31, "Travel Programs" has been re-issued and succeeds the original version published in 2011, which formally established the Defense Travel Management Office (DTMO) as the Department’s focal point to manage commercial travel programs and policy. The reissued version supersedes travel policies contained in various memos, the DoD Financial Management Regulation, Defense Transportation Regulation and other governing regulations. It contains six volumes with each volume formally outlining the procedures and regulations related to the management of a specific commercial travel program. The reissuance of DoDI 5154.31 reduces the quantity, diversity, and dispersion of commercial travel guidance by creating one location for policy information.
