Space-Available Travel (Space-A Travel)
Benefit Fact Sheet
Space Available (Space-A) travel allows authorized passengers to occupy Department of Defense (DoD) aircraft seats that are surplus after all Space Required (Space-R) passengers have been accommodated. Space-A travel costs nothing but is allowed only on a non-mission interference basis.
On April 22, 2022, Paul D. Cramer signed an updated Memorandum canceling Space-A travel program category limitations due to COVID-19 and reinstating all Space-A travel program categories as defined in Department of Defense Instruction 4515.13, Air Transportation Eligibility, Change 6.
DoD Mask Wear: On DoD Transportation Assets & DoD Transportation Hubs
All individuals, regardless of vaccination status, must wear a mask on DoD transportation assets (e.g., planes, water transport, buses, trains, taxis, and ride-shares) traveling into, within, or out of the United States, and indoor DoD transportation hubs.
These requirements apply whether the DoD transportation assets and hubs are located inside or outside the United States, but exclude ships, submarines, aircraft, and other tactical vehicles and craft in their operational environment.
Retired Army Reserve Service members are eligible for Space-A travel.
Reserve component members entitled to retired pay at age 60 (gray area retirees) may fly within the Continental United States (CONUS) and directly within/ between the CONUS and Alaska, Hawaii, Puerto Rico, the U.S. Virgin Islands, Guam, and American Samoa (Guam and American Samoa travelers may transit Hawaii or Alaska). Dependents are not authorized to travel Space A with these members. However, once the retirement age of 60 is reached and member is receiving retirement pay, no distinction is made between members retired from the Reserves/Guard and members retired from active duty. Dependents of these retirees are authorized to travel Space-A when accompanied by the sponsor. Retired Service members are not eligible for Space-Required travel.
Reservations will not be made for any Space-A passenger. Travel opportunity shall be afforded on an equitable basis to officers, enlisted personnel, civilian employees, and their accompanying dependents without regard to rank or grade, military or civilian, or branch of Uniformed Service.

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.
Space-A travel is authorized to/from Continental United States (CONUS) and Outside Continental United States (OCONUS) locations, and within/between OCONUS theatres. All travel will be on a noninterference (non-reimbursable basis).
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.
