MAD to BOS questions

Is MAD–BOS running on time right now?

Smooth skies ahead. The departure side at MAD is the weaker end, route health score 92/100. The airports section above carries the live status and delay window at both ends.

How long is the flight from MAD to BOS?

Great-circle distance is 5,474 km. With typical jet cruise speed plus taxi, climb and descent, expect roughly 416–499 min gate-to-gate on this route.

How often does MAD–BOS fly?

5 carriers operate this route, around 35 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 MAD and arrival-side delay at BOS, 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.
