ICN to KKJ questions

Is ICN–KKJ running on time right now?

Mostly on schedule. The departure side at ICN is the weaker end, route health score 78/100. The airports section above carries the live status and delay window at both ends.

How long is the flight from ICN to KKJ?

Great-circle distance is 578 km. With typical jet cruise speed plus taxi, climb and descent, expect roughly 71–80 min gate-to-gate on this route.

How often does ICN–KKJ fly?

Jin Air 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 ICN and arrival-side delay at KKJ, 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.
