Yes, Hartsfield-Jackson Atlanta International Airport (ATL) has multiple TSA PreCheck lanes and is one of the most active PreCheck hubs in the world. In 2026, PreCheck lanes are located at the Domestic Terminal North and South checkpoints, as well as the International Terminal (Maynard H. Jackson Jr. Blvd). During peak travel times, the airport utilizes "PreCheck Expansion" lanes to handle the high volume of business travelers. While there was some confusion in early 2026 due to a brief government funding lapse, the DHS quickly reversed its decision to suspend the program, ensuring that PreCheck remained operational for the public. To ensure the fastest experience, it is recommended to check the "TSA Wait Times" on the ATL airport app or website before you arrive, as the Domestic North checkpoint is often the primary location for dedicated PreCheck and CLEAR lanes.
