TSA Secondary Screening Area, Hartsfield-Jackson Atlanta International Airport

The Transportation Security Administration (TSA) operates secondary screening areas at major airports like Hartsfield-Jackson Atlanta International Airport (ATL) to ensure passenger and baggage safety. These areas are equipped with advanced scanning technology and staffed by security personnel to conduct more thorough inspections when necessary. The implementation of such measures became widespread following the September 11, 2001, terrorist attacks, fundamentally altering airport security protocols in the United States. ATL, as one of the busiest airports globally, relies on these checkpoints to maintain operational security and facilitate passenger flow.
