TSA Security Wait Times at Hartsfield-Jackson Atlanta International Airport (ATL)


As one of the world’s busiest airports, Hartsfield-Jackson Atlanta International Airport manages flights for a wide range of airlines, which adds to the overall passenger flow and congestion. Security lines at this airport can feel very different depending on when you arrive. On normal days or during mid-day hours, travelers often move through security in about 15 to 30 minutes. But during busy times, like early mornings, long weekends, or major holidays, the lines can grow quickly and sometimes take over an hour to move.

The airport’s size and high passenger volume also play a big role in how fast the process moves. To avoid long waits, many frequent flyers use services such as TSA PreCheck or CLEAR, which offer shorter lines and quicker screening. Arriving early and choosing the right checkpoint can make a big difference in starting your trip on a relaxed note.

Atlanta Airport Customs and Immigration Wait Time

At the Atlanta International Airport, most travelers usually spend around 30 to 45 minutes clearing U.S. Customs and Border Protection. However, during busy periods, especially when multiple international flights land at the same time, the process can take an hour or longer. To move through customs faster, passengers have the option to use expedited processing programs.

Travelers enrolled in Global Entry can skip the regular lines and use automated kiosks, which often saves up to 30 minutes. Mobile Passport Control (MPC) is another helpful option for U.S. citizens and eligible visitors that allows them to submit passport and customs details through a mobile app and use a faster, dedicated lane.

In addition, Atlanta Airport has rolled out a new Enhanced Passenger Processing (EPP) system that uses facial recognition technology to speed up identity checks. Early testing shows this system has helped reduce customs and immigration wait times by about 22% that makes arrivals smoother for international passengers.

How to Expedite the Security Screening Process at ATL?

Travelers can easily enroll in TSA PreCheck, CLEAR, or Global Entry to easily cross the security lines.

TSA PreCheck

TSA PreCheck lets approved travelers use special security lanes where they don’t need to remove shoes, belts, or light jackets, and can keep laptops and liquids packed in their bags. Most passengers using this service get through security in less than 10 minutes.
