To access a USO (United Service Organizations) lounge, you must be a currently serving member of the U.S. Armed Forces (Active Duty, Reserve, or National Guard) or an immediate dependent. You are required to present a valid Department of Defense (DoD) ID card, such as a Common Access Card (CAC) or a Uniformed Services ID card, at the check-in desk. Military retirees and their dependents are also eligible for access, though they may occasionally be turned away if the lounge is at its maximum capacity, as priority is always given to active-duty personnel. Unfortunately, veterans who are not retired (even those with a 100% disability rating) generally do not have access under the USO's current congressional charter. The lounges are typically located in major airports (like BWI, ATL, or DFW) and offer free food, Wi-Fi, and nap areas. They are usually staffed by volunteers and provide a much-needed "home away from home" for service members traveling on orders or for leisure.
