How many security checkpoints does SMF have?

SMF has 2 security checkpoints across 2 terminals (A, B). 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.

When is SMF security busiest?

SMF security lines are typically longest during 5–8 AM and 4–7 PM. Outside those windows, wait times drop substantially — check the SMF 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 SMF 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 SMF security checkpoint is fastest?

Terminal A typically has shorter lines due to fewer carriers; Terminal B handles roughly 70% of passengers and is Southwest-dominated.

CLEAR is not currently available at SMF. TSA PreCheck at SMF remains the best single upgrade for reducing your security wait.

What are the top SMF airport security tips?

These tips are specific to Sacramento (SMF) and verified against current airport configuration:

• Terminal B handles over 70% of SMF passengers (dominated by Southwest) — if flying American, Delta, or United in Terminal A, expect a noticeably shorter security line.
• Terminal B PreCheck closes at 4 PM, earlier than Terminal A PreCheck (6 PM); avoid relying on Terminal B's PreCheck lane for late-afternoon departures.
• Tuesday, Wednesday, and Thursday are the quietest travel days at SMF — mid-week bookings cut both security and gate-area congestion compared to Monday and Friday.
• The two terminals connect post-security by a pedestrian connector; you can walk between A and B after clearing either checkpoint without re-screening.

Does SMF have TSA PreCheck?

Yes — SMF 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 SMF 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 SMF.

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