Gatekeepers of Security: The TSA's Revival of a Lost Era The Transportation Security Administration (TSA) has introduced a new program at 13 US airports, allowing eligible TSA PreCheck members without plane tickets to pass through security and enter the gates.
This development marks a return to pre 9/11 airport dynamics, when friends and family could accompany travelers beyond the checkpoint.
In the aftermath of the September 11 attacks, airport security was drastically overhauled. ID checks, metal detectors, and passenger screening protocols significantly changed the way airports operated.
