If you're flying through Hartsfield-Jackson Atlanta International Airport (ATL), you're likely aware that it’s the busiest airport in the world. Serving over 100 million passengers each year, ATL is a major hub for domestic and international flights. With that kind of volume, one of the most important things every traveler needs to know is what to expect at the TSA security checkpoints.

Whether you’re a first-time flyer or a seasoned road warrior, understanding atl tsa wait times can help you navigate the airport more efficiently and avoid unnecessary stress before your flight.

Why ATL Has Long TSA Wait Times

Hartsfield-Jackson is not only the largest airport in the U.S. by passenger numbers, but it also acts as a key connecting hub for Delta Air Lines and dozens of international carriers. With over 275,000 passengers traveling through the airport daily, wait times at security checkpoints can fluctuate dramatically throughout the day.

Factors contributing to longer wait times include:

• High passenger traffic during peak hours

• Multiple terminals with separate checkpoints

• Security screening protocol changes

• Seasonal and holiday travel surges

This makes it crucial to keep an eye on atl tsa wait times so you can plan accordingly.

TSA Checkpoints at ATL

ATL has two primary security checkpoints for domestic travelers:

• Main Checkpoint (North and South Terminals): Most commonly used and can be heavily congested during rush hours.

• International Terminal (Concourse F): Often has shorter lines and is accessible for domestic travelers willing to take the Plane Train to their concourse.

In addition, ATL provides access to:

• TSA PreCheck Lanes: For travelers who are pre-approved for expedited screening.

• CLEAR lanes: A paid service that allows you to skip the ID check and go straight to the screening belt.

7 Tips to Minimize TSA Wait Time at ATL

6. Pack Smart: Follow TSA guidelines to avoid hold-ups (e.g., 3-1-1 rule for liquids).

7. Monitor Flight Status: Flight delays may alter crowds at checkpoints.

How Events and Holidays Impact Wait Times

ATL is heavily affected by seasonal trends. Expect longer wait times during:

• Thanksgiving week

• Christmas and New Year

• Spring Break (March-April)

• Summer vacation season (June-August)

• Large Atlanta-based events (e.g., major sports games, conventions)

During these peak periods, allow even more time to pass through security—up to 90 minutes just to clear TSA.
