Atlanta International Airport Security Wait Times commonly called Hartsfield-Jackson, can vary based on a number of variables, such as the time of day, day of the week, and season. During off-peak hours, visitors should anticipate waiting between 10 and 30 minutes for security clearance. Wait times, however, can rise dramatically during periods of high travel demand, such as the summer, vacations, or early morning rush hours, perhaps amounting to 45 minutes to an hour or longer.

It is strongly advised that travelers arrive at least two hours prior to their scheduled departure time for domestic flights and at least three hours prior to their scheduled departure time for international flights in order to guarantee a more seamless experience. Early mornings and late evenings typically have the shortest wait times if you want to avoid them.

Enrolling with TSA PreCheck might speed up the security check for people who travel regularly. By leaving laptops and complying liquids in their carry-on luggage and wearing shoes, belts, and light coats, passengers can avoid the standard screening lines by using TSA PreCheck.

Before leaving for the airport, travelers can also check the status of their security line using the airport's real-time wait time tracker, which can be accessed via the official ATL website or a number of mobile applications.
