Even with the best planning, things happen. If you’re cutting it close: Use the International Terminal checkpoint, which often has shorter lines.

And always check atl tsa wait times before leaving for the airport. https://airlinesofficesworld.com/hartsfield-jackson-atlanta-international-airport-atl-tsa-wait-times/
