How early should I get to SJU?

Luis Muñoz Marín International Airport, San Juan, PR · Checked Oct 25, 2026

The short answer

JetBlue advises arriving 2 hours before departure at San Juan, and Delta's standard US advice is also 2 hours. Southwest suggests 180 minutes at SJU. Flights to the US mainland count as domestic, but every bag first goes through USDA agricultural inspection.

Delta suggests arriving at least 3 hours before international flights.

Those are blanket rules. Your real number depends on your terminal, the time of day, traffic from your door, and whether you have PreCheck or a bag. Leave By works out your exact leave time.

Security lines at SJU

This research found no official typical wait times for SJU. In TSA's hourly screening counts for Sept 20-26, 2026, the airport was busiest from about 4am to 6am, 8am to noon, and 3pm to 5pm. The main Terminal B checkpoint handled about two-thirds of passengers. The Terminal A checkpoint was busiest around 8am and 1pm and screened no one from 7pm to 3am.

Busiest times: 4:00-6:00am, 8:00am-12:00pm, 3:00-5:00pm, Sundays and Fridays (busiest days in the TSA sample week).

Nationally, TSA checkpoints are busiest from 5 to 7 AM local time. See TSA's hourly numbers and the busiest days to fly.

TSA PreCheck: CLEAR's SJU page lists TSA PreCheck lanes at both checkpoints, Terminal A and Terminal B/C. Upgraded Points says the Terminal A PreCheck lanes are open 24 hours, but TSA's counts show no screening at that checkpoint from 7pm to 3am. The Terminal B checkpoint screened passengers around the clock. CLEAR also offers TSA PreCheck enrollment at the airport.

CLEAR: Available at this airport (see terminals below for which checkpoints).

Touchless ID: Southwest's SJU page lists a TSA PreCheck Touchless ID checkpoint. To use it, TSA says you need PreCheck, a valid passport and an opted-in airline profile, and you must carry a physical REAL ID-compliant ID as backup. This research found no list confirming which other airlines offer it at SJU.

Checking a bag

Every bag going to the mainland must pass USDA inspection before you hand it to the airline, so do that first. JetBlue: at SJU, check in at least 45 minutes before departure, with or without bags; it does not accept bags more than 4 hours before departure. Delta: check bags at least 45 minutes before US departures. American and United: domestic check-in closes 45 minutes before departure. Southwest: be at the counter with checked bags 45 minutes before departure (AP, May 2025).

SJU tips first-timers miss

  • Go to the USDA inspection station before the airline counter. Inspectors put a sticker on bags that pass. Tell them about any fruit, plants or other farm products.
  • Most fresh fruits and vegetables, pork products (including chicharrones), plants in soil, cactus and sugarcane cannot go to the mainland. Coconut, pineapple, papaya, avocado, cut flowers and coffee beans are allowed after inspection.
  • Carry-on bags are inspected too, at a marked agricultural station at the security checkpoint or the gate.
  • You do not need a passport for a direct flight to the mainland. Adults still need a REAL ID or another TSA-accepted ID.
  • On a late-night flight from Terminal A, you may need to use the Terminal B checkpoint. In TSA's September 2026 counts, the Terminal A checkpoint screened no one from 7pm to 3am. The concourses connect after security.
  • JetBlue at Terminal A will not take bags more than 4 hours before departure, and its lobby does not accept cash.
