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, refer to the directory of TMCs 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.
