ATL playbook
Live checkpoint data is temporarily unavailable for ATL, so the current number is a planning estimate and the airport-specific notes below matter more than usual.
All concourses and aircraft gates are accessible from any ATL checkpoint, so the best choice is usually the shortest live line that matches your lane.
ATL recommends arriving at least two hours before domestic departures and three hours before international departures.
During busy periods, ATL specifically recommends adding buffer for parking, rental-car drop-off, airline check-in, and security screening.

Airline notes
Delta's ATL hub volume makes domestic checkpoint choice important, but all concourses are reachable after any checkpoint.
International-terminal departures should use the International Main reading instead of assuming the domestic checkpoints reflect that flow.
Local tips
ATL publishes separate live readings for Main, North, Lower North, South, and International Main, so compare those exact checkpoint names instead of relying on a single airport average.
If you have TSA PreCheck, the Domestic South checkpoint is the main domestic PreCheck play; the International Terminal also posts specific PreCheck windows.
ATL's official security guidance calls out 5-9 AM and the days around holidays or long weekends as the busiest security periods.
