Discover Space-A!
A comprehensive guide to military travel benefits, what works well in your Space-A article, and strategic suggestions for strengthening its structure and reach.
Few people realize this—even members of the military—but travel can actually be cheaper for military dependents. This process is known as Space-A, or “Space Available” travel. I will dive into this, but suffice it to say, this is the process by which active-duty or retired military members and their dependents may fly on aircraft operated by the U.S. Air Force’s Air Mobility Command (AMC). However, there are numerous restrictions. (The Space-A travel site is active and available here: https://www.amc.af.mil/AMC-Travel-Site/AMC-Space-Available-Travel-Page/.)
These restrictions include the requirement to abide by all U.S. Air Force (USAF) and Department of Defense regulations. The USAF states on its site that Space-A travel is a privilege of service, not a right. Military operational travel always comes first, and there is no guarantee of travel. “Space Available” means exactly that—if there is space available on the aircraft, you may receive a seat. There is no contract of carriage like those used by commercial airlines.
This is the United States Air Force, not American Airlines, and that distinction is made very clear.
Travelers must depart from a U.S. or overseas USAF passenger terminal, typically located on an Air Force Base with an Air Mobility Command presence. The U.S. has a limited number of AMC-dominated terminals, which do not include fighter or bomber bases. These include Baltimore/Washington International Thurgood Marshall Airport (which hosts an Air National Guard wing), Dover Air Force Base in the Washington, D.C. area, Fairchild Air Force Base near Spokane, Washington, Joint Base Andrews in Maryland, Joint Base Charleston in South Carolina, Joint Base Lewis-McChord near Seattle, Washington, and Joint Base McGuire-Dix-Lakehurst in New Jersey, one of the largest AMC departure points.
Seattle-Tacoma International Airport also hosts an Air National Guard wing, giving western Washington two nearby options. Travis Air Force Base in Fairfield, California, is especially notable as one of the largest U.S. Air Force bases in the world and features a dedicated passenger terminal for Space-A travelers flying to Europe aboard C-17 Globemaster III and C-5M Super Galaxy aircraft.
Military family members may also apply to travel on the Patriot Express, which is still part of the Space-A system but operates on contracted civilian aircraft rather than cargo aircraft.
To apply for Space-A travel, eligible service members must email the departure terminal’s passenger office with required information, including:
- Email address
- Rank/grade
- Full name (first, middle, last)
- Service branch
- Military status
- Names of dependent travelers
- Total number of seats required
- Eligibility category
- Leave dates
- Overseas travel readiness status (required documents such as passport, military ID, dependent IDs)
- Destination(s) (up to five may be listed)
As the Air Force states, Space-Available travel allows authorized military personnel, retirees, and their families to fly free or at greatly reduced cost on Department of Defense aircraft, primarily operated by the Air Mobility Command.
Travelers are placed into one of six categories, unlike civilian airline boarding groups:
- Category I: Emergency leave (EL)
- Category II: Environmental and morale leave (EML)
- Category III: Active duty on ordinary leave (ADOL) and Medal of Honor recipients
- Category IV: Unaccompanied dependents of deployed members (on EML)
- Category V: Permissive travel orders or TDY, and authorized students
- Category VI: Retirees, dependents, and 100% disabled veterans (with approved VA documentation)
Travelers must have required leave documentation when applicable. They must monitor a 72-hour flight schedule for departing AMC aircraft at their desired terminal. They must also be physically present at the passenger terminal to compete for seats. In many cases, boarding is first come, first served.
Space-A travel is highly unpredictable. Flights are military missions and may be delayed, changed, or canceled with little notice. Flexibility is essential, along with a backup plan and sufficient funds to purchase a commercial flight if stranded domestically or internationally.
Civilian airlines do have a loosely comparable system, often used by flight attendants and crew to reach connecting assignments. Major crew bases include Minneapolis–Saint Paul International Airport and Chicago O’Hare International Airport. Many flight attendants also receive family travel benefits and “buddy travel” privileges.
The Space-A experience is often described as “hurry up and wait.” Travelers may sit in larger-than-average economy-style seating compared to commercial aircraft. Luggage is typically secured with military cargo. On aircraft such as the C-17 Globemaster III, C-5 Super Galaxy, or C-130 Hercules, passengers may sit in jump seats along the fuselage or webbed “crash seats.”
Noise levels can be significant, and ear protection or noise-canceling headphones are strongly recommended. On longer flights, passengers may rest on sleeping bags or mats when space allows. Aviation enthusiasts may even experience aerial refueling, typically with a KC-135 Stratotanker, lasting approximately 15–20 minutes—an experience not found in commercial aviation.
