In what ways does the DTS customer service assist travelers?

The choice that indicates DTS customer service assists travelers by resolving technical and policy-related queries is correct because the primary role of DTS customer service is to support users in navigating the system and understanding the policies that govern travel. Users may encounter various issues related to the functionality of DTS or have questions concerning travel regulations, per diem rates, and reimbursement processes. Customer service staff are equipped to tackle these inquiries, ensuring that travelers have the information they need to manage their travel efficiently and effectively.

In contrast, while alternative travel options, real-time flight updates, and managing travel itineraries can enhance the overall travel experience, such services may not be the primary responsibility of the DTS customer service. The focus of this support system is to ensure clarity and assistance regarding the technical aspects of the DTS and the policies travelers must adhere to.
