What type of support can travelers expect from DTS customer service?

The correct response highlights the specific role of DTS customer service in addressing technical issues and ensuring travelers understand the various policies associated with the Defense Travel System. DTS customer service provides valuable support by helping users navigate the system, resolve any software-related problems they may encounter while using it, and clarify complex regulations or guidelines related to travel. This assistance is crucial for ensuring that travelers can effectively utilize the DTS for their travel arrangements without encountering unnecessary difficulties.

While other answer choices provide services that might be expected in a general travel assistance context, they do not align with the specific functions of DTS customer service. For instance, while help with bookings and reservations and travel advisory services may be essential for travelers, these services are typically not provided by customer support related to DTS itself. Instead, DTS focuses on ensuring users can operate within the system efficiently and understand any applicable travel policies, which is essential for compliance and successful travel management within the Department of Defense framework.
