Is IAD–ICN running on time right now?

Mostly on schedule. The departure side at IAD is the weaker end, route health score 80/100. The airports section above carries the live status and delay window at both ends.

How long is the flight from IAD to ICN?

Great-circle distance is 11,174 km. With typical jet cruise speed plus taxi, climb and descent, expect roughly 819–988 min gate-to-gate on this route.

How often does IAD–ICN fly?

2 carriers operate this route, around 13 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 IAD 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.
