Which component is responsible for approving travel and claim submissions in DTS?

The Approving Official (AO) plays a critical role in the Defense Travel System (DTS) by being responsible for reviewing and approving travel and claim submissions made by travelers. This oversight ensures that all travel requests align with policy, budget allowances, and mission requirements. The AO's approval is necessary before any reimbursement can be processed, which is crucial for maintaining financial accountability within the travel management process. In essence, the AO acts as a gatekeeper to confirm that travel has been properly authorized and is justifiable, thus ensuring that the travel funds are used appropriately and in compliance with regulations.
