Overview of Hartsfield-Jackson Atlanta International Airport
Hartsfield-Jackson Atlanta International Airport sits about seven miles south of downtown Atlanta. The airport serves as one of the most important aviation hubs in North America.
ATL has maintained its status as the world’s busiest airport by passenger volume for many years, processing over 100 million passengers annually in recent travel cycles.
Key facts about ATL include:

What TSA PreCheck Is
TSA PreCheck is a trusted traveler program operated by the Transportation Security Administration (TSA). The program identifies travelers considered low-risk through a background check and identity verification.
Approved participants receive a Known Traveler Number (KTN) that links to airline reservations.
When a traveler enters this number during ticket booking, their boarding pass may display the TSA PreCheck indicator. This allows them to use expedited screening lanes.
Benefits of TSA PreCheck include:
- Access to dedicated security lanes
- No need to remove shoes or belts
- Laptops and liquids remain inside carry-on bags
- Light jackets can remain on during screening
These advantages significantly reduce the time spent at airport security checkpoints.

ATL operates several security checkpoints across its terminals.
Each checkpoint processes large numbers of passengers daily.
Common checkpoints include:

- North Checkpoint serving specific airlines and passenger flows

TSA PreCheck lanes operate at these checkpoints depending on staffing levels and passenger demand.
Travelers should check their airline instructions or airport guidance to determine which checkpoint is best for their flight.
