FSD to LAS questions

Is FSD–LAS running on time right now?

Significant delay risk. The arrival side at LAS is the weaker end, route health score 45/100. The airports section above carries the live status and delay window at both ends.

How long is the flight from FSD to LAS?

Great-circle distance is 1,774 km. With typical jet cruise speed plus taxi, climb and descent, expect roughly 155–182 min gate-to-gate on this route.

How often does FSD–LAS fly?

Allegiant Air runs the route with about 4 flights a week (sun, mon, 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 FSD and arrival-side delay at LAS, 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.
