Charlotte Douglas International Airport – TSA and Air National Guard restricted areas

Charlotte Douglas International Airport operates federally regulated security checkpoints run by the Transportation Security Administration that restrict public access to sterile areas beyond ticketing. The airport is also the base for the North Carolina Air National Guard's 145th Airlift Wing, which maintains military facilities and airfield areas with controlled access. Airside areas, ramps, and certain operational facilities at the airport require authorized badges or escorts for entry. The airport is one of the busiest hubs in the U.S., increasing the scale of its secured zones.
