HGH to DNH questions
How long is the flight from HGH to DNH?
Great-circle distance is 2,565 km. With typical jet cruise speed plus taxi, climb and descent, expect roughly 211–250 min gate-to-gate on this route.
How often does HGH–DNH fly?
Air China runs the route with about 6 flights a week (sun, mon, tue, 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 HGH and arrival-side delay at DNH, 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.
