ICN to WNZ questions
Is ICN–WNZ running on time right now?
Mostly on schedule. The departure side at ICN is the weaker end, route health score 74/100. The airports section above carries the live status and delay window at both ends.
How long is the flight from ICN to WNZ?
Great-circle distance is 1,183 km. With typical jet cruise speed plus taxi, climb and descent, expect roughly 114–131 min gate-to-gate on this route.
How often does ICN–WNZ fly?
Air China runs the route with about 4 flights a week (mon, wed, fri, sat). 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 WNZ, 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.
