BOS to ZRH questions

Is BOS–ZRH running on time right now?

Significant delay risk. The departure side at BOS is the weaker end, route health score 50/100. The airports section above carries the live status and delay window at both ends.

How long is the flight from BOS to ZRH?

Great-circle distance is 6,010 km. With typical jet cruise speed plus taxi, climb and descent, expect roughly 454–545 min gate-to-gate on this route.

How often does BOS–ZRH fly?

Swiss International Air Lines runs the route with about 7 flights a week (daily). 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 BOS 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.
