Travel Assistance Center

The Travel Assistance Center (TAC) provides DoD-wide support for issues unresolved or unaddressed at the local level. Staffed by a team of trained analysts, the TAC offers escalated assistance across the spectrum of defense travel including help with DTS issues, Commercial Travel Programs, and Travel Policy.

The TAC surveys users to measure the quality of assistance provided. This feedback allows us to identify potential problems, pinpoint process improvements, and improve overall traveler satisfaction.

Submit a Help Ticket

Request help with an issue or check on the status of an existing ticket by logging into Passport. Navigate to Trax, then choose Travel Assistance from the left-side menu.

When creating a ticket:

  • Make the title specific (e.g. Authorization EWMIAMIFL102120_A01 stuck at CTO Submit)
  • Enter a detailed description of the problem. Include a systematic sequence of what happened and any incurred error codes. If it is a DTS problem, include the DTS screen number. Do not include any Personally Identifiable Information (PII) in the description field (other fields are secure).
  • Consider attaching a screenshot to the ticket. Note, any attachment must be formatted as a PDF.
  • From the drop down menu, select a subject, then a category, then a sub-category for your issue if necessary. Based on your choices, additional fields may display. Complete all fields with as much detail as possible. This information is used to route your ticket for the fastest resolution.

Click "Submit" to save the ticket. You will prompted to review the FAQs for a solution. If an answer is found, select "My Question is Answered" to discard the ticket. If a resolution to your issue cannot be found, select "Finish Submitting Ticket." You will receive an email to confirm your ticket has been received, as well as follow up emails any time the ticket is updated.


Reach the TAC by phone at 1-888-Help1Go (888-435-7146) at any time. Overseas callers may dial this number directly from any DSN line. Before you call, make sure the information you’re seeking isn’t readily available in the self-help resources in TraX or from your local help desk. Large call volume may result in longer hold times and often peaks around mid-day, Eastern Time.

Your analyst will ask for the same information that would be provided in the online help ticket form. Gather information before connecting with an analyst to speed up the ticket entry process considerably.

Outreach Calls

The TAC hosts Outreach Calls to keep travelers informed of the latest developments related to the Defense Travel System, the Joint Travel Regulations, and other major travel programs. Calls are held on the second and fourth Tuesday of each month, at 0800 and 1300 ET. Upcoming calls, agenda items, and dial-in information are announced on TraX and through the TAC RSS Feed. Users may also download the presentation slides for an upcoming or past call.
