Which of the following should be done if travel authorizations need to be changed?

When travel authorizations require changes, the proper course of action is to amend the existing travel authorization in the Defense Travel System (DTS). This process is essential because amending allows for the original authorization to maintain its history while reflecting any updates or modifications.

Using the amendment process ensures that all stakeholders involved in the travel, including finance and approving officials, have a record of the changes made. This method keeps the travel information streamlined and helps avoid confusion or potential issues that can arise from submitting a completely new authorization request. Additionally, by using the amendment feature, you ensure that the authorization retains its unique tracking number and associated travel data, which is crucial for accurate accounting and oversight.

This operational procedure aligns with the overall goal of maintaining clear and consistent travel records within the DTS, thereby facilitating an efficient travel experience for service members and authorized travelers.
