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 4:56 PM. That is 30 min driving, 6 min to park, about 8 min at security when you reach it around 5:32 PM, 5 min to walk to the gate and 15 min spare before boarding: 64 minutes door to gate. Change any of it below for your own flight.

Questions people ask about BOI
How early should I get to BOI?
For a domestic flight out of Boise, plan to be inside the terminal about an hour before departure, and about an hour for an international one. That covers a 10 to 20 minute checkpoint queue at the Thursday 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 BOI security?
Thursday around noon, when 6 departures' worth of passengers are converging on the checkpoint at once. The calmest hour with real traffic is Saturday at 6 pm, at roughly 5 minutes.
Is TSA PreCheck worth it at BOI?
At the Thursday peak it turns a 10 to 20 minute queue into something closer to 5 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 BOI?
Boise Air Terminal/Gowen Field 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.
