What are the key components included in a travel authorization?

The correct answer emphasizes the essential elements that form a travel authorization within the Defense Travel System (DTS). A travel authorization typically includes the travel itinerary, which outlines the locations and sequence of travel; estimated costs, which provide a financial framework for the trip; and the purpose of travel, which justifies the need for the trip within the context of the mission or official duty.

These components are critical as they ensure clear communication of what the travel involves and its associated costs, helping to facilitate the approval process by those in authority. This rigor reinforces accountability and transparency in travel expenditures and underscores the necessity of aligning travel plans with the official objectives of the organization, particularly in a military or defense context.

Other options present relevant information, but they do not encapsulate the comprehensive requirements of a travel authorization as effectively as the selected answer. For instance, while personal details about the traveler may be necessary for identification, they do not directly contribute to the purpose and structure of the travel authorization itself.
