What is the primary source of information for allowances and reimbursable expenses for TDY travel?

The primary source of information for allowances and reimbursable expenses for Temporary Duty (TDY) travel is the Joint Travel Regulations (JTR). The JTR serves as the authoritative guide governing the travel and transportation allowances for members of the uniformed services, as well as specific guidelines for their dependents. It establishes the rates and procedures that apply to TDY travel, including per diem rates for lodging and meals, which are essential for assessing reimbursements.

The regulations outlined in the JTR ensure that service members are appropriately compensated for travel-related expenses while on duty. This includes detailed provisions covering various aspects of travel, from lodging and meals to transportation reimbursements, making it a comprehensive resource for understanding what is permissible under government regulations.

While the Federal Travel Regulations (FTR), Travel Policy Guide, and Agency Travel Manual might also provide guidance and outline policies for federal employees and other travelers, they do not specifically cater to the unique needs and scenarios associated with military TDY travel in the same way that the JTR does. The JTR's focus on military regulations and its detailed approach make it the key reference for allowances and reimbursements during TDY travel.
