Security wait times at Hartsfield-Jackson Atlanta International Airport can change quickly due to its round-the-clock operations and heavy passenger traffic. Security Wait Times at ATL Airport typically average between 15 and 30 minutes for travelers using standard TSA screening on regular travel days. During quieter periods such as late nights and late mornings, lines are usually shorter and move more efficiently. However, peak travel windows—including early mornings, late afternoons, weekends, and holiday seasons—often result in longer waits that may exceed an hour. The airport’s multiple terminals and overlapping flight schedules can also contribute to congestion. To enjoy a smoother experience, passengers are encouraged to arrive early, stay prepared for screening, and consider expedited options like TSA PreCheck or CLEAR when available.
