Pro Flight Search — Denver (DEN) to Butte (BTM) route reliability, measured from operated flights on official airport boards.

Smooth skies ahead. The departure side at DEN is the weaker end, route health score 86/100. The airports section above carries the live status and delay window at both ends.
Great-circle distance is 929 km. With typical jet cruise speed plus taxi, climb and descent, expect roughly 96–110 min gate-to-gate on this route.
United Airlines runs the route with about 6 flights a week (mon, tue, wed, thu, fri, sat). Since one carrier owns the route, a single disruption tends to ripple through the day.
A blend of departure-side delay at DEN and arrival-side delay at BTM, 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.
