How the Colorado Springs to St Louis route actually runs
Pro Flight Search records official board updates for nonstop COS to STL flights through the day: schedules, estimates, gate pushes and actual departures. The verdict above comes from operated flights, so it reflects what this route does rather than what the timetable promises.

COS to STL questions
Is COS–STL running on time right now?
Significant delay risk. The arrival side at STL is the weaker end, route health score 38/100. The airports section above carries the live status and delay window at both ends.
How long is the flight from COS to STL?
Great-circle distance is 1,241 km. With typical jet cruise speed plus taxi, climb and descent, expect roughly 118–136 min gate-to-gate on this route.
How often does COS–STL fly?
Jet Linx Aviation runs the route with about 1 flight a week (tue). Since one carrier owns the route, a single disruption tends to ripple through the day.
What does the route health score measure?
A blend of departure-side delay at COS and arrival-side delay at STL, computed from rolling delay windows (refreshed every 40 minutes) with a daily-rollup fallback. Current MVFR, IFR, or LIFR endpoint weather caps the score when flight rules can limit throughput. Higher is healthier: 100 means operations are clean at both ends.
