Sacramento (SMF) TSA wait times

Sacramento International Airport schedules 161 departures on an average day, and pushes up to 13 of them in a single hour. The checkpoint feels that: expect roughly 15 to 30 minutes in the standard lanes at the Monday 5 am peak, and closer to 5 minutes at Monday 10 pm.

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 4:44 PM. That is 30 min driving, 10 min to park, about 13 min at security when you reach it around 5:24 PM, 8 min to walk to the gate and 15 min spare before boarding: 76 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 14min

    Open to everyone. Usually 10 to 20.

  • PreCheck 5min

    Saves 9 min. TSA pre-approved travellers. Usually 5 to 10.

  • CLEAR 4min

    Saves 10 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 SMF

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

  • Southwest 57%
  • SkyWest regional 17%
  • United 8%
  • American 7%
  • Delta 6%
  • Alaska 3%
  • Hawaiian 1%
  • Frontier 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?

The checkpoint is busiest around 5 am today, at about 19 min. Fill in your flight above to see where your own trip lands.

Questions people ask about SMF

How early should I get to SMF?

For a domestic flight out of Sacramento, plan to be inside the terminal about an hour before departure, and about an hour and a quarter for an international one. That covers a 15 to 30 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 SMF security?

Monday around 5 am, when 13 departures' worth of passengers are converging on the checkpoint at once. The calmest hour with real traffic is Monday at 10 pm, at roughly 5 minutes.

Is TSA PreCheck worth it at SMF?

At the Monday peak it turns a 15 to 30 minute queue into something closer to 7 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 SMF?

Sacramento 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.
