The Defense Travel System (DTS) is a software application for the US Department of Defense that allows employees to manage their business travel.

DTS allows employees to create authorizations (TDY travel orders), prepare travel reservations, receive approvals, generate travel vouchers, and receive a split reimbursement between their bank accounts and the Government Travel Charge Card (GTCC) vendor.

DTS operates at over 9,500 total sites worldwide, and on average, DTS processes more than 25,000 transactions while approximately 100,000 unique users access it on a daily basis. Defense Manpower Data Center (DMDC) Program Management Office DTS (PMO-DTS) has the program oversight (acquisition, technical, operation and maintenance) oversight of DTS while the Defense Travel Management Office (DTMO) has functional oversight.[1][2]
