How the Saga to Seoul route actually runs
Pro Flight Search records official board updates for nonstop HSG 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.

HSG to ICN questions
Is HSG–ICN running on time right now?
Smooth skies ahead. The arrival side at ICN is the weaker end, route health score 90/100. The airports section above carries the live status and delay window at both ends.
How long is the flight from HSG to ICN?
Great-circle distance is 594 km. With typical jet cruise speed plus taxi, climb and descent, expect roughly 72–81 min gate-to-gate on this route.
How often does HSG–ICN fly?
Trinity Airways runs the route with about 4 flights a week (sun, mon, wed, fri). 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 HSG 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.
