Navigating Atlanta Airport security wait times can be challenging, especially during peak hours. Typically, wait times range from 15 to 30 minutes, but they can extend up to 60 minutes during busy periods like early mornings and holidays. To ensure a smooth journey, it's advisable to arrive at least two hours before domestic flights and three hours prior to international departures. Enrolling in programs like TSA PreCheck or CLEAR can significantly reduce your wait time, often to under 10 minutes .
