SOF to ZRH questions

Is SOF–ZRH running on time right now?

Smooth skies ahead. Both endpoints currently score the same, route health score 100/100. The airports section above carries the live status and delay window at both ends.

How long is the flight from SOF to ZRH?

Great-circle distance is 1,279 km. With typical jet cruise speed plus taxi, climb and descent, expect roughly 120–140 min gate-to-gate on this route.

How often does SOF–ZRH fly?

2 carriers operate this route, around 9 flights a week between them. Compare carrier days and times in the airline list above.

What does the route health score measure?

A blend of departure-side delay at SOF and arrival-side delay at ZRH, 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.
