What are the two main methods for booking travel in DTS?

The primary methods for booking travel in the Defense Travel System (DTS) are through the DTS web application or by utilizing a travel agent. The DTS web application allows users to manage their travel arrangements directly, accessing features tailored specifically for government travel, such as itinerary creation, expense tracking, and approvals. This method promotes efficiency and convenience as travelers can handle their bookings at any time from any location with internet access.

Additionally, travel agents can provide support for more complex itineraries or special circumstances, ensuring that all travel regulations and policies are adhered to. They can assist travelers who may have questions or face challenges while using the DTS system.

The other options listed do not align with the official methods prescribed for DTS travel bookings. Booking via phone, fax, or email requests are not standard practices within DTS and can lead to misunderstandings or miscommunications due to the lack of real-time access to travel information and automated systems that track travel history and expenses. Therefore, the most effective and recognized ways to book travel in DTS are through the web application or through a travel agent.
