Who uses the JTR?

The JTR, Joint Travel Regulations, is used by members of the Uniformed Services and Department of Defense civilian employees and their dependents when traveling on official government business. Specifically, JTR applies to Army, Navy, Air Force, Marines, Coast Guard, Space Force, Public Health Service, NOAA, and DoD civilian employees, including Army Corps of Engineers civilians, plus their eligible dependents traveling under orders. JTR is also used by travel approving officials, finance offices, and Defense Travel Management Office to determine what is reimbursable. Contractors working for DoD may be subject to JTR if contract states, but generally JTR is for military and DoD civilians, not all federal employees. Other federal agencies like Department of State, Justice, and Interior use Federal Travel Regulation FTR, not JTR, though JTR incorporates FTR principles. Uniformed Services members use JTR for temporary duty TDY, permanent change of station PCS, deployment, and training travel. DoD civilians use JTR for TDY and PCS as well. Dependents use JTR when traveling on dependent travel orders, such as PCS moves. Defense Travel System DTS, the booking tool, enforces JTR rules automatically. So JTR users are primarily military personnel, DoD civilians, and their families traveling officially, plus the administrative personnel who approve and reimburse their travel, ensuring consistent travel policy across Department of Defense.
