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.

The return home from combat can often leave servicemembers feeling out of place with the most important people in their lives - their families.
"In deployment, Soldiers grow accustomed to a new lifestyle and a new 'family' - those buddies that bond together to defend each other," said Maj. Ken Williams, 14th Military Police Brigade chaplain. "This lifestyle change is prolonged and becomes familiar, i.e., the new normal."
The families also change while the Soldier is deployed.
"The family is a system," Williams said. "When one family member is absent, the whole system changes. All members of the family adapt to a new 'normal' way of life."
When the servicemember returns, the family may feel uncomfortable with each other, and the servicemember may withdraw from the family.
