GRU to BOS questions

Is GRU–BOS running on time right now?

Significant delay risk. The arrival side at BOS is the weaker end, route health score 42/100. The airports section above carries the live status and delay window at both ends.

How long is the flight from GRU to BOS?

Great-circle distance is 7,738 km. With typical jet cruise speed plus taxi, climb and descent, expect roughly 576–693 min gate-to-gate on this route.

How often does GRU–BOS fly?

2 carriers operate this route, around 7 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 GRU 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.
