Standard, PreCheck, and CLEAR security lanes
Terminals and security at SAN
Which airline you fly decides your terminal. Terminal 1 runs the longest lines here. The per-terminal minute is modeled from each terminal's share of departures, not measured. All terminals connect after security, so a quieter checkpoint is an option.
Flying out of San Diego: what to know
Two separate terminals, three checkpoints
SAN has two terminals that do not connect after security. Terminal 1 runs a single central checkpoint, while Terminal 2 splits screening between an east and a west checkpoint that both feed one shared concourse, so within Terminal 2 you can walk freely once you clear. Between Terminal 1 and Terminal 2, though, there is no airside link, so you must clear at your own airline's building.
PreCheck at every checkpoint, CLEAR in Terminal 2
TSA PreCheck lanes run at every SAN checkpoint, in Terminal 1 and at both Terminal 2 checkpoints, though hours vary by location. CLEAR is present at the airport, with a CLEAR and PreCheck enrollment location in Terminal 2 near the west checkpoint. Because the terminals are separate after security, use the PreCheck or CLEAR lane at the checkpoint that serves your own gate.
Early-morning peak, heavier in Terminal 2
Early mornings are the peak here, with the first departure banks stacking up before dawn, and Terminal 2, home to the larger carriers, tends to see heavier lines than Terminal 1. Check which terminal your airline uses before choosing a checkpoint, since you cannot clear in one and walk to the other. If your gate is in Terminal 2, either the east or west checkpoint reaches it.
Regional carriers fly these routes under the mainline brands, so a SkyWest flight shows on your ticket as Delta, United, American or Alaska.
SAN security, common questions
How early should I get to SAN?
For a domestic flight out of San Diego, plan to be inside the terminal about an hour before departure, and about an hour and a half for an international one. That covers a 20 to 35 minute checkpoint queue at the Friday 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 SAN security?
Friday around 7 am, when 21 departures' worth of passengers are converging on the checkpoint at once. The calmest hour with real traffic is Wednesday at 9 pm, at roughly 7 minutes.
Is TSA PreCheck worth it at SAN?
At the Friday peak it turns a 20 to 35 minute queue into something closer to 9 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 SAN?
San Diego 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 3 am, and checkpoints generally open about two hours before the first flight of the day.
How long is security at San Diego?
At the Friday peak around 7 am, the standard lane at SAN typically runs 20 to 35 minutes. Away from the peak it settles to roughly 7 minutes. These are modeled from the airport's own departure schedule, so they move hour by hour, which is what the chart on this page shows.
How much time does PreCheck save at SAN?
At the busy Friday peak, PreCheck turns the standard 20 to 35 minute wait into about 9 minutes, a saving of roughly 18 minutes when it matters most. Off-peak the two lanes are much closer, because a short line is short in either one.
Which terminal is Southwest at SAN?
Southwest departs from Terminal 1 at San Diego International Airport and flies 38% of the airport's departures. Your terminal is set by the airline you fly, so check your boarding pass for the gate.
Tips for SAN, from the data
