Planning a trip through Hartsfield-Jackson Atlanta International Airport (ATL)? You’re not alone. As the busiest airport in the world by passenger volume, ATL welcomes more than 275,000 passengers a day. Whether you’re a frequent flyer or a first-time traveler, there’s one thing that can make or break your experience at ATL: the TSA wait times.
Understanding tsa wait times atl is one of the smartest steps you can take when preparing to travel. This guide will walk you through what to expect, how to plan, and how to get through ATL’s security lines with confidence.
Why TSA Wait Times at ATL Are Unique
Unlike smaller airports, ATL doesn’t have downtime. There’s a constant stream of travelers, and multiple airlines use the airport as a major hub—especially Delta, which has its headquarters here. In addition to domestic traffic, ATL sees a substantial number of international flights, further adding to its congestion.
Because of this, TSA wait times can vary drastically depending on:
-
Time of day
-
Day of the week
-
Airline and terminal
-
Season or holiday
A quick glance at average wait time might not cut it—real-time updates and proper planning are your best allies.
TSA Checkpoints at ATL: What You Need to Know
There are four main security checkpoints across ATL’s terminals. Knowing your options can help you avoid the busiest ones.
✈️ Main Security Checkpoint
Located between the North and South Terminals. This is the default checkpoint for many travelers and often the most crowded.
✈️ North Checkpoint
Ideal for Delta travelers and often slightly faster than the Main checkpoint, especially during off-peak hours.
✈️ South Checkpoint
Also heavily used by Delta passengers. It has TSA PreCheck and CLEAR lanes, making it a good option for expedited screening.
✈️ Concourse F (International Terminal)
If you’re departing internationally, you’ll likely use the security checkpoint here. It generally has shorter lines, especially in the evenings.
Each checkpoint offers TSA PreCheck, and CLEAR is available at Main, North, and South.

Real-World Examples: The Difference Prep Makes
Let’s look at two travelers on the same day:
Ava books a 6:45 AM flight. She arrives at 6:00 AM, unaware that morning is the busiest time at ATL. The line at the Main checkpoint stretches far beyond the ropes. No PreCheck. No CLEAR. She misses her flight by 5 minutes.
Leo books the same flight but arrives by 5:15 AM. He checks tsa wait times atl beforehand and opts for the South checkpoint, which is moving faster. He has TSA PreCheck and is through security in under 10 minutes—with enough time to grab a coffee.
The difference? Planning.
