How airport security screening changed after 9/11

The events of 9/11 fundamentally transformed airport security screening and operational protocols. At CLT, the attacks led to immediate lockdowns and a complete overhaul of safety measures. Since then, the airport has implemented significant changes to its infrastructure and screening processes to enhance passenger safety. These systemic shifts reflect a broader national evolution in aviation security, moving from basic checks to the rigorous, multi-layered screening standards currently utilized across all major airports to prevent future threats.
