Within how many hours does DTS auto-cancel reservations if the authorization has not been stamped SIGNED?

The correct answer is 24 hours. In the context of the DTS (Defense Travel System) process, if a reservation authorization remains unconfirmed with a SIGNED stamp, the system will automatically cancel that reservation after 24 hours. This process helps to free up resources and ensures that travel accommodations are not held unnecessarily, providing better access to available options for other users. Understanding this timeframe is essential for travel planners and individuals using the system, as it underscores the importance of timely actions in confirming reservations to avoid inconveniences or the need to make last-minute bookings.
