Travel Management Company Assistance

Travel Management Companies (TMCs, or Commercial Travel Offices/CTOs as they're referred to in the Defense Travel System) arrange official travel on behalf of military and civilian travelers in accordance with DoD Instruction 5154. 31, Vol. 2 [whs.mil, PDF, 11 pages].

Contact Your TMC

You can find contact information for your TMC on your travel itinerary. If you need assistance after normal business hours, look up the after-hours TMC contact information in the table below. Contact the TMC if:

• An emergency or mission requirement demands short-notice travel (verbal orders of the Commanding Officer, or VOCO),
• Official travel has begun and you need to make changes to your itinerary,
• You need to return any unused paper tickets.

If travel has not yet begun, you can:

• Use your DoD Online Booking Tool reservation module,
• Look for answers in the Knowledge Center of TraX [login required] through the Passport portal,
• Get advice from your local help desk Defense Travel Administrator or Authorizing Official,
• Contact the Travel Assistance Center.
