TFU to CNX questions
How long is the flight from TFU to CNX?
Great-circle distance is 1,399 km. With typical jet cruise speed plus taxi, climb and descent, expect roughly 129–150 min gate-to-gate on this route.
How often does TFU–CNX fly?
Chengdu Airlines runs the route with about 3 flights a week (sun, 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 TFU 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.
