AD PLACEMENT — CONTEXTUAL
Check your boarding pass for terminal assignment, since American and United typically use Terminal A while Southwest and most others use Terminal B.
The airside connector between terminals is a straightforward walk with minimal foot traffic congestion, so transfers rarely take more than 10-15 minutes.
If arriving from Mexico, budget extra time for Federal Inspection Services before you can proceed to your connecting gate.
SAT's small size means gate-to-gate distances are short, but confirm gate numbers on arrival screens since the airport doesn't have many connecting-passenger information desks.
Because SAT is primarily an origin-destination airport, connections are less common and staff may be less experienced handling tight transfers, so ask a gate agent directly if you're worried about time.

Moderate
High risk
Tight connections are safer outside peak hours. Morning rush (6–9a), midday (11a–2p), and evening (4–8p) are highest risk.
Terminals A and B are joined by a post-security airside walkway, so most passengers can move between concourses without leaving the secure area or re-clearing screening. International arrivals from a handful of Mexico flights go through Federal Inspection and re-enter the secure zone, which adds time compared to a domestic-to-domestic connection.
