During our frequent trips to various "blues" events or to visit family around the country, we have occasion to spend time in Charlotte, S.C. airport...and we really don't mind the delay there because we always find a warm welcome, a place to relax, and refresh...The USO club, graciously offer these amenities to both active duty and retired military personel and their dependents.
In addition to the USO benefits, the airport in it's self is beautiful and well designed.
