Hartsfield-Jackson was not part of the initial rollout last year. TSA installed the new CT machines after the Super Bowl in Atlanta, which brought records crowds through the airport.
The installation was completed in the spring, and Hartsfield-Jackson is now one of more than 15 airports around the country with the machines. Right now, they are used only at the international terminal, and not at the Atlanta airport's domestic terminal security checkpoints.
The lanes with the CT machines are also smart lanes that have four stations for passengers to load their carry-ons into bins.
The two new second-generation smart lanes, which are paid for by Delta Air Lines, also address some of the issues that have frustrated frequent travelers who use the smart lanes at the domestic terminal.
At the stations for passengers to load their carry-ons into bins, there are indicator lights below that show when a station is available.
After filling a bin, a traveler can immediately push it forward. The bin sits in a middle track, where it is automatically queued onto the conveyor belt. That reduces the need for travelers to jockey for a spot to push their bin onto the moving conveyor belt.
At the end of screening, travelers can leave their empty bins on the belt instead of having to stack them at the end. The conveyor belt automatically drops each empty bin onto a stack that is routed back to the start of screening to be reused.
Delta’s senior vice president of airport customer service Gareth Joyce said in a written statement that making the investments to speed up the security process is part of its efforts to “help reduce customers’ stress.”
