These operational notes prefer the structured airport facts snapshot, then fall back to the accepted airport reference at flystl.com, then blend that with local timezone, route, and city-access data already on this page.
These are the specific situations where this airport page earns its keep: time-zone conversion, city transfer planning, nearby airport backup logic, and source-confidence checks before acting.
STL uses America/Chicago (CDT, UTC-05:00). Use this before overnight arrivals, cross-date departures, and same-day connections.
