AD PLACEMENT — CONTEXTUAL
Almost all connections at SMF are domestic-to-domestic, so the tram ride between Terminal A and Terminal B is usually the only obstacle.
If arriving on one of SMF's limited international flights (mainly from Mexico), budget extra time for Customs and Border Protection processing in Terminal B before continuing.
Check which terminal your arriving and departing flights use in advance, as Southwest and some others operate primarily from Terminal B while Delta, American, and United use Terminal A.
Because SMF has relatively low flight frequency to many destinations, a missed connection can mean a multi-hour wait for the next flight, so don't cut it close.
TSA PreCheck lines are typically short and fast here, making it a good airport to use PreCheck status if you have a tight connection.

Low risk
Moderate
High risk
Tight connections are safer outside peak hours. Morning rush (6–9a), midday (11a–2p), and evening (4–8p) are highest risk.
Terminal A and Terminal B are connected airside by an automated people-mover tram that takes about 3-5 minutes, with walking to and from tram stations adding to the total. International arrivals (limited to a handful of Mexico flights) go through Customs and Border Protection in Terminal B before any connection, but there is no separate security re-screening for domestic-to-domestic transfers since both terminals sit inside one security perimeter.
