AD PLACEMENT — CONTEXTUAL
Check whether your connection requires a terminal change, since that means clearing security again via the outdoor walkway.
Use TSA PreCheck if eligible, as SJC's checkpoints are small and lines can back up fast during peak banks.
Southwest passengers connecting within Terminal B rarely need to worry about the inter-terminal walk.
International arrivals (from Mexico, Canada, Asia, or Europe) go through federal inspection at Terminal B before any connection, so build in extra time.
SJC is compact, so even worst-case gate-to-gate walks within a single terminal are short.

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 by an outdoor/covered pedestrian walkway (the 'Terminal Connector') located pre-security, so passengers switching terminals must exit the secure area and go through TSA screening again on the other side. There is no train or shuttle system since the walk between terminals takes only about 8-12 minutes.
