DTW to ICN questions

Is DTW–ICN running on time right now?

Smooth skies ahead. The departure side at DTW is the weaker end, route health score 91/100. The airports section above carries the live status and delay window at both ends.

How long is the flight from DTW to ICN?

Great-circle distance is 10,655 km. With typical jet cruise speed plus taxi, climb and descent, expect roughly 782–943 min gate-to-gate on this route.

How often does DTW–ICN fly?

Delta Air Lines 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 DTW and arrival-side delay at ICN, 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.
