ATL security, common questions
How early should I get to ATL?
For a domestic flight out of Atlanta, plan to be inside the terminal about an hour and a quarter before departure, and about an hour and a half for an international one. That covers a 25 to 50 minute checkpoint queue at the Monday peak plus the walk to the gate. Outside the peak you can safely trim it; the calculator above works it out from your actual departure time.
What is the busiest time at ATL security?
Monday around 7 am, when 64 departures' worth of passengers are converging on the checkpoint at once. The calmest hour with real traffic is Sunday at 4 am, at roughly 6 minutes.
Is TSA PreCheck worth it at ATL?
At the Monday peak it turns a 25 to 50 minute queue into something closer to 12 minutes. Over a five year membership that is worth it if you fly more than about three round trips a year through an airport this busy. The trusted traveler calculator prices it against your own flying.
When does security open at ATL?
Hartsfield Jackson Atlanta International Airport does not publish checkpoint opening hours in any national feed, so we will not invent them. What the schedule does show is that the first departures leave around 2 am, and checkpoints generally open about two hours before the first flight of the day.
Tips for ATL, from the data
- Fly between (22, 4) if you can. That window sits between the two daily rushes, when the checkpoint is at its calmest.
- The 7 am hour is the single busiest today, at about 33 minutes in the standard lane.
- Delta runs 80% of departures here, so its checkpoints and gates carry the most traffic. Which airline you fly is what decides your terminal.
