How the Jeju City to Zhengzhou route actually runs

CJU to CGO questions
Is CJU–CGO running on time right now?
Mostly on schedule. The departure side at CJU is the weaker end, route health score 72/100. The airports section above carries the live status and delay window at both ends.
How long is the flight from CJU to CGO?
Great-circle distance is 1,171 km. With typical jet cruise speed plus taxi, climb and descent, expect roughly 113–130 min gate-to-gate on this route.
How often does CJU–CGO fly?
West Air runs the route with about 4 flights a week (sun, wed, thu, 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 CJU and arrival-side delay at CGO, 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.
