LHR to DTW questions

Is LHR–DTW running on time right now?

Smooth skies ahead. The departure side at LHR is the weaker end, route health score 82/100. The airports section above carries the live status and delay window at both ends.

How long is the flight from LHR to DTW?

Great-circle distance is 6,044 km. With typical jet cruise speed plus taxi, climb and descent, expect roughly 457–548 min gate-to-gate on this route.

How often does LHR–DTW fly?

3 carriers operate this route, around 21 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 DTW, 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.
