GRU to ORD questions

Is GRU–ORD running on time right now?

Smooth skies ahead. The departure side at GRU is the weaker end, route health score 88/100. The airports section above carries the live status and delay window at both ends.

How long is the flight from GRU to ORD?

Great-circle distance is 8,428 km. With typical jet cruise speed plus taxi, climb and descent, expect roughly 625–752 min gate-to-gate on this route.

How often does GRU–ORD fly?

United Airlines 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 GRU and arrival-side delay at ORD, 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.
