Standard, PreCheck, and CLEAR security lanes
Terminals and security at SJU
Which airline you fly decides your terminal. Terminal A 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 Juan: what to know
Two checkpoints across a connected airside
San Juan runs two main security checkpoints, one in Terminal A and one in Terminal B, and the concourses connect by covered walkways inside the secure area, so connecting passengers can move between them. Clear at either checkpoint for your airline and you can reach your gate on foot, though the walk to the far concourses is real distance. Terminal A's checkpoint keeps the longest hours.
PreCheck in both terminals, CLEAR too
TSA PreCheck lanes are at both the Terminal A and Terminal B checkpoints, and the Terminal A PreCheck lane is open 24 hours, which matters at a hub with red-eye Caribbean and mainland departures. CLEAR is present, with kiosks at the main checkpoints in both terminals. PreCheck can roughly halve the standard wait here, which helps most in the winter and summer crush described below.
Peaks in winter holidays and summer
San Juan is the Caribbean's busiest airport and a leisure gateway, so its peaks track vacation seasons rather than a weekday commute. Traffic swells around the December holidays and again through July and August, plus local events like the San Sebastian Street Festival in January, when lines can run 30 to 50 percent longer than usual. In those windows, arrive earlier than you would for a business hub and lean on PreCheck.
SJU security, common questions
How early should I get to SJU?
For a domestic flight out of San Juan, 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 Saturday 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 SJU security?
Saturday around 1 pm, when 9 departures' worth of passengers are converging on the checkpoint at once. The calmest hour with real traffic is Thursday at 8 pm, at roughly 5 minutes.
Is TSA PreCheck worth it at SJU?
At the Saturday 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 traveler calculator prices it against your own flying.
When does security open at SJU?
Luis Munoz Marin 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 midnight, and checkpoints generally open about two hours before the first flight of the day.
How long is security at San Juan?
At the Saturday peak around 1 pm, the standard lane at SJU typically runs 15 to 30 minutes. Away from the peak it settles to roughly 5 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 SJU?
At the busy Saturday peak, PreCheck turns the standard 15 to 30 minute wait into about 7 minutes, a saving of roughly 15 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 JetBlue at SJU?
JetBlue departs from Terminal A at Luis Munoz Marin International Airport and flies 35% of the airport's departures. Your terminal is set by the airline you fly, so check your boarding pass for the gate.
