KMG to CNX questions
Morning or evening flight on KMG–CNX?
Operators schedule morning departures around 06:55 from KMG. Earlier flights typically land before destination-airport delays accumulate later in the day; check the CNX delay card to confirm conditions when you'd arrive.
How long is the flight from KMG to CNX?
Great-circle distance is 814 km. With typical jet cruise speed plus taxi, climb and descent, expect roughly 87–100 min gate-to-gate on this route.
How often does KMG–CNX fly?
China Eastern Airlines runs the route with about 17 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 KMG and arrival-side delay at CNX, 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.
