BOS to NZY questions

Is BOS–NZY running on time right now?

Mostly on schedule. The departure side at BOS is the weaker end, route health score 78/100. The airports section above carries the live status and delay window at both ends.

How long is the flight from BOS to NZY?

Great-circle distance is 4,160 km. With typical jet cruise speed plus taxi, climb and descent, expect roughly 324–387 min gate-to-gate on this route.

What does the route health score measure?

A blend of departure-side delay at BOS and arrival-side delay at NZY, 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.
