Great Circle Mapper's featured map for 24 March 2026: "US Airports Without TSA" - 20 US airports opted to hire private security screening rather than use the Department of Homeland Security's Transportation Security Administration #TSA screeners since the time TSA was established in 2001. Those airports are not affected by the current TSA funding stalemate and worker shortage. http://www.gcmap.com/featured/20260324 #aviation #travel #avgeek #mapgeek
