Constructed Travel

Constructed travel is used to compare travel costs when a traveler requests approval to use a form of transportation other than the normal mode of transportation (airline) or airport selection other than IAD (Dulles) during the week.  Traveler will need to submit a request, Constructed Travel Worksheet, which is then placed in the DTS substantiating document section.

Mandatory Split Disbursement

All DoD personnel are required to split disburse all undisputed charges against the GOVCC (IBA).  Payment for all GOVCC charges will be sent directly to the GOVCC contractor (Citi). To support the split disbursement requirement, DTS will automatically split disburse airline, hotel, rental vehicle, and other miscellaneous expenses identified by the traveler as charged to the GOVCC.
