BTM to BIL questions

Is BTM–BIL running on time right now?

High disruption likely. The arrival side at BIL is the weaker end, route health score 0/100. The airports section above carries the live status and delay window at both ends.

How long is the flight from BTM to BIL?

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 BTM–BIL fly?

Alpine Air Express 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.

What does the route health score measure?

A blend of departure-side delay at BTM and arrival-side delay at BIL, 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.
