Space-A travel

There are rules and guidelines which apply to such travel. Uniformed personnel may only travel Space-A while on leave or pass for the full duration of their Space-A trip, and Space-A travel cannot be used in conjunction with travel required by the service. Space A travel may not be used for personal financial gain or in connection with business enterprises or employment. Other nations' laws and policies, as well as U.S. foreign policy, may limit the ability to travel using Space-A.

Aside from members of the United States Marine Corps, travelers do not have to be in uniform for their flights.

Eligible passengers wanting to travel using DoD Space-A travel are required to sign up at the departing location and are then placed on a locally managed Space-A register. The registration process varies depending on the location, but most locations allow signups via electronic mail, fax, or postal mail.

Each location's passenger service center maintains their own Space-A register. Each person signing up is placed on this register using category of travel, signup date and signup time.

Based on status (active duty military, retired military, emergency traveler, etc.), Space-A travel applicants are assigned a category of travel from 1 to 6, which categorizes their priority of movement, 1 being the highest priority. Thus, an applicant with priority 1 will gain a place on an available aircraft over an applicant with priority 4, for example.

The number of space-available seats may not be known until the flight's "Roll Call" just prior to the flight departs. After sorting the signup register by category of travel and signup date, the passenger terminal personnel follow a selection procedure. If there is sufficient seating for everyone desiring a seat, then everyone boards; otherwise, a cutoff point is determined.

The branches of service eligible for Space-A travel are:

• United States Navy
• United States Marine Corps
• United States Army
• United States Air Force
• United States Coast Guard
• United States Space Force
• United States Public Health Service
• National Oceanic and Atmospheric Administration

Space-A travel is not without its pitfalls. Unlike traditional commercial air traffic, military flights are not always assigned predictable takeoff times. Many factors go into planning a military flight, with space-required cargo and passengers forming the basis of planning. There is no consideration given to potential Space-A travelers during the planning process.

Uniformed Services Retirees (receiving retirement pay and possessing a BLUE Retiree ID Card) and their accompanying dependents can travel Space-A anywhere that Space-A is allowed.

"Gray Area" Retirees have limited eligibility (but not their dependents). DoD reg, Section 4, Table 3, a Gray Area Retiree (Reservist who is "eligible" for retirement pay at 60 years of age but not fully retired with a BLUE ID Card), can fly Space-A only within the CONUS and directly between the CONUS and Alaska, Hawaii, Puerto Rico, the US Virgin Islands, Guam, and American Samoa (Guam and American Samoa travelers may transit Hawaii or Alaska); or traveling within Alaska, Hawaii, Puerto Rico or the Virgin Islands.

As of August 13th 2018, authorized veterans with a permanent service-connected disability rated 100% as total are eligible for Space-A travel traveling in the CONUS or directly between the Continental United States CONUS and Alaska, Hawaii, Puerto Rico, the U.S. Virgin Islands, Guam, and American Samoa (Guam and American Samoa travelers may transit Hawaii or Alaska); or traveling within Alaska, Hawaii, Puerto Rico or the U.S. Virgin Islands. Dependents and caregivers of 100% disabled veterans are not eligible to fly Space-A.
