Maps are updated when terminals are renovated or new concourses open. Terminal 5 at LAX, for example, has been closed since October 2025 for reconstruction — always confirm your terminal from your boarding pass rather than relying on a saved map.
Here is what each terminal or concourse at SMF handles — which airlines fly from it, the gate range, and key amenities to know before you go.
Gates A1–A13 (13 gates). Serves Air Canada, American Airlines, Delta Air Lines, and United Airlines. Older building with typically lighter crowds than Terminal B. TSA PreCheck open 3 AM–6 PM.
Gates B1–B19 (19 gates). Serves Alaska Airlines, Aeromexico, Frontier Airlines, Hawaiian Airlines, JetBlue, Southwest Airlines, and Volaris. Newer 2011 building. Southwest handles over 50% of SMF passengers. TSA PreCheck open 4 AM–4 PM (earlier closure than Terminal A).
Two separate terminal buildings connected by a post-security pedestrian connector — passengers can walk between Terminal A and Terminal B after clearing security at either checkpoint without re-screening.
Timing tip
Always allow 15–30 minutes for any inter-terminal transfer at SMF — wait times for people-movers, buses, or security re-screening add up faster than the physical distance suggests. Build the buffer into your Leave-By time, not your gate arrival time.
Terminal B handles 70%+ of passengers (dominated by Southwest) — if flying American, Delta, or United via Terminal A, you will typically encounter a shorter security line. Terminal B PreCheck closes earlier at 4 PM versus Terminal A at 6 PM; plan accordingly for afternoon departures from Terminal B. Tuesday, Wednesday, and Thursday are the quietest travel days at SMF — mid-week bookings cut both security and gate wait times measurably.
