FSD to AZA questions
Is FSD–AZA running on time right now?
Smooth skies ahead. The departure side at FSD is the weaker end, route health score 82/100. The airports section above carries the live status and delay window at both ends.
How long is the flight from FSD to AZA?
Great-circle distance is 1,725 km. With typical jet cruise speed plus taxi, climb and descent, expect roughly 152–178 min gate-to-gate on this route.
How often does FSD–AZA fly?
Allegiant Air runs the route with about 5 flights a week (mon, wed, 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 AZA, 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.
