What must a traveler create before starting their trip in DTS?

Before starting a trip in the Defense Travel System (DTS), a traveler must create a travel authorization. This document serves to formally request permission for travel and outlines important details such as the purpose, dates, and estimated costs associated with the trip. The travel authorization is crucial for ensuring that the expense is approved and that the traveler adheres to organizational protocols. It ensures that funds are allocated appropriately and compliance with federal travel regulations is maintained. This step is vital as it provides a framework for all subsequent travel arrangements and expense reporting.

In contrast, an expense report is submitted after the trip has concluded to account for the expenditures incurred, while a budget proposal is typically far earlier in the planning process and not necessarily a requirement for individual trips. A travel voucher is also submitted post-travel to claim reimbursement for expenses incurred during the trip.
