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.
Retired National Guard Service members are eligible for Space-A travel.
