What Affects TSA Wait Times at ATL?

Several factors influence how long you'll spend in the TSA line at ATL:

• Time of Day: Early mornings (5 AM – 8 AM) and late afternoons (3 PM – 7 PM) are consistently the busiest. These are the golden hours for business travelers and flight connections.
• Day of the Week: Mondays and Fridays typically see the heaviest traffic. Mondays bring in business commuters, while Fridays usher in weekend travelers.
• Holidays and Special Events: Spring break, Thanksgiving, Christmas, and major conventions can create surges in traffic, resulting in longer security lines.
• Airline and Terminal: Delta operates the majority of flights at ATL and uses the South Terminal checkpoint, which can often get backed up. If you're flying a different airline, the North Terminal checkpoint may be slightly less crowded.

Where to Find TSA Checkpoints at ATL

ATL offers three main TSA checkpoints:

• South Checkpoint (Domestic Terminal): Heavily used by Delta passengers.
• North Checkpoint (Domestic Terminal): Used by other domestic carriers.
• International Terminal Checkpoint (Concourse F): Often has shorter lines and is open to domestic travelers not checking bags.

Pro Tip: If you're not checking bags and have a boarding pass, using the International Terminal checkpoint might be a smart move. From there, the Plane Train can take you to your departure concourse quickly.
