Space Available Flight: An Overview

AC-130HU

Space Available Flight, better known as Space A or military hops, is a unique privilege provided to servicemembers, retirees and their families. Under the Space-Available (Space A) program, eligible passengers can fill unused seats on DoD-owned or controlled aircraft once all the space-required (duty) passengers and cargo have been accommodated.

If you have the time and flexibility, Space A travel offers incredible discounts. We have gathered valuable resources to help you better understand the Space A system and prepare you for what to expect.
