"...One of the coolest benefits of being a military retiree (besides the pension) is the opportunity to fly space-available on military planes.
Also known as “Space-A,” “taking a hop,” or “MAC flying,” it’s a great way to get free flights to destinations all over the world.
Most flights, a.k.a. “missions,” are from one U.S. military base to another, but you will see occasional flights to civilian airports.
Flying Space-A is best when you have time, flexibility, and a sense of adventure.
The biggest challenge for active duty travelers is the unpredictable nature of Space-A flying.
Passenger terminals publish flight schedules only 72 hours in advance, and you won’t know until the last minute if you have a seat.
But the aspects of Space-A flying that make it inconvenient for active duty on leave make it the perfect option for retirees who have a lot of flexibility.
Wondering if Space-A travel is right for you? Take a look at these 5 reasons why flying Space-A is a great way for military retirees to travel...."
