BIL to BTM questions

Is BIL–BTM running on time right now?

Mostly on schedule. The departure side at BIL is the weaker end, route health score 78/100. The airports section above carries the live status and delay window at both ends.

How long is the flight from BIL to BTM?

Great-circle distance is 306 km. With typical jet cruise speed plus taxi, climb and descent, expect roughly 52–56 min gate-to-gate on this route.

How often does BIL–BTM fly?

Alpine Air Express runs the route with about 4 flights a week (tue, wed, thu, fri). 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 BIL 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.
