| The authorization
(formerly called a DD Form 1610 or Travel Order) is
the document on which all of the initial travel requests,
modifications, and payment decisions are recorded. This
single trip document includes information about travel
reservations, the itinerary, the should-cost estimate,
the Line of Accounting (LOA – the DTS term for
a fund cite), and any updates made during the trip.
You use DTS to review the should-cost and all arrangements,
relying on the system's built-in edit and policy checks.
When the traveler creates the authorization, justification
must be given for any exceptions to travel policy. You
will review these justifications and approve or deny
them in accordance with mission requirements and
You must also consider whether the military traveler
should use government lodging and mess, if they are
available. Your approval authority allows wide latitude
in making changes to the arrangements when necessary.
