San Juan (SJU) Security Tips

SJU has 2 security checkpoints with TSA PreCheck lanes and CLEAR biometric lanes. Security is busiest 5–9am and 3–6pm. Use the Leave-By Time calculator to fold the modeled SJU wait forecast, your drive, and gate-walk into one exact departure time.

How many security checkpoints does SJU have?

SJU has 2 security checkpoints across 4 terminals (A, B, C, D). TSA PreCheck dedicated lanes are available, giving members a faster, bin-free screening experience. PreCheck is open at the main checkpoints during regular screening hours, though an individual lane can close off-peak. CLEAR biometric kiosks are also deployed at SJU, letting enrolled members skip the ID-verification queue entirely. See CLEAR at SJU for details.

When is SJU security busiest?

SJU security lines are typically longest during 5–9am and 3–6pm. Outside those windows, wait times drop substantially — check the SJU wait forecast for the current picture before you head out. General guidance:

• Domestic flights: arrive at least 2 hours before departure; 2.5 hours during peak periods.
• International flights: arrive at least 3 hours before departure to cover check-in, security, and any customs pre-clearance.

Not sure when to leave? The Leave-By Time calculator uses the modeled SJU wait forecast, real-time traffic, and your gate-walk distance to give you an exact departure time. Also see how early to arrive at the airport for a full breakdown by flight type.

Which SJU security checkpoint is fastest?

The consolidated Terminal B/C/D checkpoint generally has more lanes and moves faster at peak times than the standalone Terminal A checkpoint — but use whichever matches your departure terminal, and budget extra time at Terminal A during a morning JetBlue bank..

CLEAR is available at SJU and can be stacked with TSA PreCheck for the fastest path through security: CLEAR handles the biometric ID verification, PreCheck handles the bin-free lane. If you frequently travel through SJU during peak windows, combining both programs is the most effective approach. See CLEAR at SJU for kiosk locations and current status.

What are the top SJU airport security tips?

These tips are specific to San Juan (SJU) and verified against current airport configuration:

• SJU has only two checkpoints total: one dedicated to Terminal A (JetBlue, Air Canada, Avelo, Tradewind) and one consolidated checkpoint serving Terminals B, C, and D together — confirm you're heading to the right one before you queue.
• CLEAR+ operates at both checkpoints (Terminal A roughly 4am–6pm; Terminal B/C roughly 4am–8:30/9pm), but Terminal A's CLEAR lane has been intermittently unavailable due to TSA staffing shortages — don't rely on it as a guaranteed fallback.
• Average security wait runs 20–30 minutes and can stretch longer during the 5–9am and 3–6pm peak banks; TSA PreCheck typically cuts this roughly in half.
• Terminal A runs on a completely separate checkpoint from Terminals B/C/D — if you're connecting between Terminal A and any other terminal, you must exit and re-clear security, so build in real extra time rather than assuming an airside walk.
• There is no confirmed dedicated family security lane at SJU; ask a TSA officer at either checkpoint if you need extra time or space for children or additional assistance.

Does SJU have TSA PreCheck?

Yes — SJU has TSA PreCheck lanes at its security checkpoints. PreCheck members keep shoes, belts, light jackets, laptops, and 3-1-1 liquids packed, and pass through a dedicated screening lane. Membership costs $85–$100 for five years and includes a Known Traveler Number (KTN) you add to every booking.

See live PreCheck wait times and current lane status on the SJU TSA PreCheck page. That page also covers which terminals have a PreCheck lane, enrollment locations, and how PreCheck compares to CLEAR and Global Entry at SJU.

Global Entry interviews can be completed at SJU itself — via an on-site enrollment center or Enrollment on Arrival after an international flight — and membership includes TSA PreCheck. See Global Entry at SJU for locations and hours.
