Tips for 45 min Connections
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.

High risk
Tight connections are safer outside peak hours. Morning rush (6–9a), midday (11a–2p), and evening (4–8p) are highest risk.
Getting Between Concourses
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.
