What each line is

When should you leave?

Worked from the wait actually running at this checkpoint at the hour you will be here, not a fixed buffer.

Example. For a 6:00 PM domestic flight today, leave home about 4:18 PM. That is 30 min driving, 18 min to park, about 24 min at security when you reach it around 5:06 PM, 15 min to walk to the gate and 15 min spare before boarding: 102 minutes door to gate. Change any of it below for your own flight.

Door to terminal kerb, before traffic. We add the traffic for the hour you would actually be driving.

Which security line?

The three ways through the checkpoint at this airport, what each is running right now, and what the faster ones save you.

  • Standard 27min

    Open to everyone. Usually 20 to 40.

  • PreCheck 9min

    Saves 18 min. TSA pre-approved travellers. Usually 5 to 15.

  • CLEAR 7min

    Saves 20 min. Biometric check, then to the front. Usually 5 to 10.

PreCheck and CLEAR are separate programmes. PreCheck is a lighter screening you qualify for; CLEAR verifies who you are and walks you to the front of whichever line you are already entitled to use.

Airlines at ATL

Which airline you are flying decides your terminal and checkpoint. This is the share of ATL's departures each one runs, from the published schedule.

  • Delta 78%
  • Frontier 6%
  • Southwest 6%
  • United 2%
  • American 2%
  • SkyWest regional 2%
  • Spirit 2%
  • PSA Airlines regional 1%

Regional carriers (SkyWest, Envoy, PSA, Republic) fly these routes under the mainline brands, so a SkyWest flight shows on your ticket as Delta, United, American or Alaska.

For the terminal your gate is in, check your airline's boarding pass or the airport's official map. We do not model terminal-by-terminal waits yet, and we will not guess at them.

Is another time better?

Questions people ask about ATL

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 traveller 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.
