LHR to ORD questions

Is LHR–ORD running on time right now?

Significant delay risk. The arrival side at ORD is the weaker end, route health score 45/100. The airports section above carries the live status and delay window at both ends.

How long is the flight from LHR to ORD?

Great-circle distance is 6,343 km. With typical jet cruise speed plus taxi, climb and descent, expect roughly 478–574 min gate-to-gate on this route.

How often does LHR–ORD fly?

3 carriers operate this route, around 49 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 LHR 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.
