TSA security wait times at Hartsfield-Jackson Atlanta International Airport can vary depending on the time of day, travel season, and passenger volume, directly impacting ATL Security Wait Times. On average, travelers moving through standard TSA checkpoints experience wait times of around 15 to 30 minutes on regular days. During off-peak hours, such as late mornings, early afternoons, and overnight periods, lines often move quickly and may take less than 15 minutes. However, early mornings, evenings, weekends, and holiday travel periods usually see heavier crowds, which can cause wait times to exceed an hour. To reduce delays, passengers are encouraged to arrive early and consider using expedited screening options like TSA PreCheck or CLEAR for a smoother airport experience.
