Tips for 1¾ hr Connections
Check whether your connecting gate is in Terminal 1 or Terminal 2, since a mismatch adds real transit time.
Southwest passengers usually stay within Terminal 1, making same-terminal connections quick.
If you must switch terminals, allow at least 30 minutes given walkway distance and potential re-screening.
Precheck lines are typically short at STL, so enrolled travelers can shave several minutes off security.
International arrivals (limited to a few flights like Air Canada) go through Terminal 2 and always require a fresh security screening before connecting.
Busyness — Connection Risk

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.
Getting Between Concourses
Terminal 1 and Terminal 2 are connected by an enclosed pedestrian walkway of roughly 10-15 minutes, as well as a free shuttle bus and the MetroLink light rail (a couple of stops), both of which take 10-20 minutes depending on waits. Passengers connecting within the same terminal rarely need to leave the secure area, but those switching terminals who exit security may need to clear TSA screening again on the other side.
