Who is responsible for maintaining the overall DTS?

The Office of Defense Travel Administration (ODTA) is responsible for maintaining the overall Defense Travel System (DTS). This central body oversees the operation and maintenance of the DTS, ensuring that the system functions effectively for all service members and departments utilizing it. The ODTA develops policies, manages system updates, and provides support for users to facilitate a streamlined travel process within the Department of Defense.

In contrast, while the other roles mentioned play important parts in the support and administration of travel at local or specific levels, they do not encompass the comprehensive management and oversight responsibilities that the ODTA holds for the entire DTS. For instance, the Department of Travel Administration (DTA) focuses on travel administration but lacks the overarching authority of the ODTA. Similarly, the Local Defense Travel Administrator (LDTA) and Finance and Defense Travel Administrator (FDTA) operate within more specialized or localized scopes and are not tasked with the overall integrity and functionality of the DTS as a whole. Thus, the ODTA is identified as the principal organization responsible for the comprehensive oversight of the DTS.
