Timing your arrival can be the difference between a stress-free stroll through security and a full-blown panic sprint to your gate. Here’s what you should know about when the lines tend to stack up:
Early Mornings (5 AM – 9 AM): Expect a surge of business travelers. The lines start building around 5 AM and peak around 7 AM.
Late Afternoon (3 PM – 6 PM): This wave comes with the rush of outbound domestic and connecting flights.
Fridays and Sundays: These are notoriously busy as they cap the workweek and bookend the weekend getaways.
Holiday Travel Windows: Thanksgiving, Christmas, Spring Break, and summer travel season can see record-breaking wait times.
Checking updated atl tsa wait times before you leave home can save you from guessing and help you schedule your airport arrival more accurately.
Inside the Checkpoints: What Are Your Options?
ATL offers several security checkpoints across its terminals. Each has different wait times depending on the time of day and passenger flow.
1. Main Domestic Terminal Checkpoint
Serves most passengers, especially those flying Delta.
Features standard, PreCheck, and CLEAR lanes.
Tends to be the busiest checkpoint overall.
2. North and South Security Lanes
North: Delta-focused, still crowded but often faster than the main.
South: Serves other airlines, can sometimes be the quicker option depending on traffic.
3. International Terminal (Concourse F)
A hidden gem. If you have carry-on only and a boarding pass, you may be allowed through here even for domestic flights.
Lines here are often dramatically shorter, especially mid-day and evening.
