of the last 39 operated PUS → ICN flights arrived within 15 minutes
Pro Flight Search records official board updates for nonstop PUS to ICN flights through the day: schedules, estimates, gate pushes and actual departures. The verdict above comes from operated flights, so it reflects what this route does rather than what the timetable promises.
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 PUS to ICN?
Great-circle distance is 338 km. With typical jet cruise speed plus taxi, climb and descent, expect roughly 54–59 min gate-to-gate on this route.
How often does PUS–ICN fly?
KOREAN AIRLINES runs the route with about 35 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 PUS 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.
