1. Main Security Checkpoint
Located in the Domestic Terminal, this is the most commonly used checkpoint—and often the most crowded.
2. North & South Checkpoints
These serve specific airlines and tend to have shorter lines. They're especially convenient for passengers with TSA PreCheck or CLEAR.
3. International Terminal Checkpoint (Concourse F)
For travelers flying internationally, this checkpoint usually experiences lighter traffic and may offer quicker processing times.
All of these checkpoints are tracked in real-time on the tsa wait times atl page, which allows passengers to choose the shortest line before they even enter the airport.
