TFU to LGW questions
Is TFU–LGW running on time right now?
Significant delay risk. The arrival side at LGW is the weaker end, route health score 50/100. The airports section above carries the live status and delay window at both ends.
How long is the flight from TFU to LGW?
Great-circle distance is 8,356 km. With typical jet cruise speed plus taxi, climb and descent, expect roughly 620–746 min gate-to-gate on this route.
How often does TFU–LGW fly?
Air China runs the route with about 2 flights a week (sun, 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 LGW, 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.
