Space-A Travel is a privilege (not an entitlement) that is afforded to Uniformed Services members, retirees and dependents as an avenue of respite from the rigors of Uniformed Services duty and may offer substantial savings for your leisure travel plans. Remember there is no guaranteed space for any traveler. The Department of Defense is not obligated to continue an individual's travel or return them to their point of origin or any other point. Travelers should have sufficient personal funds to pay for commercial transportation to return to their residence or duty station if space-available transportation is not available.

Transportation may be between overseas stations, between Continental United States (CONUS) stations, and between overseas and CONUS stations where adequate border clearance facilities exist or can be made readily available.

Space Available Travel is permitted, provided all space-required passengers and cargo have been accommodated. Space Available transportation is allowed on a non-interference basis only. DoD aircraft, including training missions, will not be scheduled or sized to accommodate the movement of passengers on a space-available basis. Space-available transportation will not be used for personal gain or for a business enterprise. No additional funds may be used or flight hours performed to provide transportation under the space-available travel program.
