The USO (United Service Organizations) airport lounges are primarily designed for active-duty military members, Reserve, and National Guard, along with their lawful dependents. However, the access policy is slightly broader than just "active duty." Retired military personnel with a valid Department of Defense (DoD) ID card are generally welcome to use the facilities, though they are sometimes admitted on a "space-available" basis if the lounge is near its maximum capacity. Some locations also extend a warm welcome to Gold Star Families. It is important to note that most USO centers do not grant access to veterans who served but did not reach retirement status, nor do they allow access for civilian government employees or contractors without specific military orders. These lounges provide a vital "home away from home" with free food, Wi-Fi, and sleeping areas, funded entirely by private donations to support those currently bearing the burden of service and their families.
