Defense Transportation System Travelers who have booked and arranged their official travel using DTS system, are required to provide copies of the official travel orders to the local Sato travel office within 72 hours of the scheduled flight.
Without official travel orders, invoices cannot be reconciled and submitted to Defense Finance and Accounting Services Indianapolis for payment.
If the traveler is unable to present the orders to Sato, then the official who directed the travel is responsible for doing so.
For details, contact your local official travel office.
