HAN to ORD questions
Is HAN–ORD running on time right now?
Significant delay risk. The arrival side at ORD is the weaker end, route health score 39/100. The airports section above carries the live status and delay window at both ends.
How long is the flight from HAN to ORD?
Great-circle distance is 12,847 km. With typical jet cruise speed plus taxi, climb and descent, expect roughly 937–1131 min gate-to-gate on this route.
How often does HAN–ORD fly?
Air Chathams runs the route with about 1 flight a week (wed). 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 HAN 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.
