KTI to ICN questions
Is KTI–ICN running on time right now?
Smooth skies ahead. Both endpoints currently score the same, route health score 100/100. The airports section above carries the live status and delay window at both ends.
How long is the flight from KTI to ICN?
Great-circle distance is 3,437 km. With typical jet cruise speed plus taxi, climb and descent, expect roughly 273–325 min gate-to-gate on this route.
How often does KTI–ICN fly?
3 carriers operate this route, around 18 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 KTI 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.
