Summary

The Secretary of Defense may create a program to let eligible people fly on Department of Defense aircraft when there are spare seats. If the Secretary decides to start the program, they must write the rules within one year and must send Congress a report within 30 days saying why, any extra groups who will be covered, how the program will follow the rules below, and how success will be measured. The program must be budget-neutral: no extra money or extra flight hours can be used. People who can be covered include active-duty members; Selected Reserve members with a valid ID card; retired regular or reserve members (including certain reserve retirees who are under the age in section 12731); veterans rated as totally disabled from service; dependents the Secretary names in the rules; and any other groups the Secretary allows. The Secretary can set travel priorities based on military needs, humanitarian reasons, and morale, but must give priority to regular and reserve active-duty members and their dependents. The Secretary must also control costs, ensure safety and security, and can limit who gets the benefit if needed. A special rule says a retired member living in a U.S. Commonwealth or possession who is referred by a local primary care provider to outside specialty care must get the same priority as an unaccompanied adult dependent on leave for both trips to and from care; if that retired member is an under‑age Retired Reserve, that priority applies only if they are enrolled in TRICARE under section 1076e. Veterans with total disabilities cannot be given priority over active members or their dependents. The Department does not have to modify aircraft or equipment for passengers, and flight commanders keep final say over boarding and safe operation. This authority is in addition to any other DoD space-available travel authority.

(2)Members of the Selected Reserve who hold a valid Uniformed Services Identification and Privilege Card.

(d)In operating the travel program, the Secretary of Defense shall—
(1)in the sole discretion of the Secretary, establish an order of priority for transportation under the travel program for categories of eligible individuals that is based on considerations of military necessity, humanitarian concerns, and enhancement of morale;
(2)give priority in consideration of transportation under the travel program to the demands of members of the armed forces in the regular components and in the reserve components on active duty and to the need to provide such members, and their dependents, a means of respite from such demands; and
(3)implement policies aimed at ensuring cost control (as required by subsection (b)) and the safety, security, and efficient processing of travelers, including limiting the benefit under the travel program to one or more categories of otherwise eligible individuals if considered necessary by the Secretary.
(e)(1)Notwithstanding subsection (d)(1), in establishing space-available transportation priorities under the travel program, the Secretary of Defense shall provide transportation for an individual described in paragraph (2), and a single dependent of the individual if needed to accompany the individual, at a priority level in the same category as the priority level for an unaccompanied dependent over the age of 18 traveling on environmental and morale leave.
(2)Subject to paragraph (3), paragraph (1) applies with respect to an individual described in subsection (c)(3) who—
(A)resides in or is located in a Commonwealth or possession of the United States; and
(B)is referred by a military or civilian primary care provider located in that Commonwealth or possession to a specialty care provider for services to be provided outside of that Commonwealth or possession.

(4)The priority for space-available transportation required by this subsection applies with respect to both—
(A)the travel from the Commonwealth or possession of the United States to receive the specialty care services; and
(B)the return travel.
(5)The requirement to provide transportation on Department of Defense aircraft on a space-available basis on the priority basis described in paragraph (1) to individuals covered by this subsection applies whether or not the travel program is established under this section.

(f)(1)Travel may not be provided under this section to a veteran eligible for travel pursuant to subsection (c)(4) in priority over any member eligible for travel under subsection (c)(1) or any dependent of such a member eligible for travel under this section.
(2)The authority in subsection (c)(4) may not be construed as affecting or in any way imposing on the Department of Defense, any armed force, or any commercial company with which they contract an obligation or expectation that they will retrofit or alter, in any way, military aircraft or commercial aircraft, or related equipment or facilities, used or leased by the Department or such armed force to accommodate passengers provided travel under such authority on account of disability.
(3)The authority in subsection (c)(4) may not be construed as preempting the authority of a flight commander to determine who boards the aircraft and any other matters in connection with safe operation of the aircraft.
