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

GMP to ICN questions
Is GMP–ICN running on time right now?
Smooth skies ahead. The departure side at GMP is the weaker end, route health score 82/100. The airports section above carries the live status and delay window at both ends.
How long is the flight from GMP to ICN?
Great-circle distance is 34 km. With typical jet cruise speed plus taxi, climb and descent, expect roughly 32–33 min gate-to-gate on this route.
How often does GMP–ICN fly?
Eastar Jet runs the route with about 1 flight a week (mon). 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 GMP 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.
