How the London to Chengdu route actually runs
Pro Flight Search records official board updates for nonstop LHR to TFU flights through the day: schedules, estimates, gate pushes and actual departures. The verdict above comes from operated flights, so it reflects what this route does rather than what the timetable promises.

LHR to TFU questions
Is LHR–TFU running on time right now?
Some delays possible. The departure side at LHR is the weaker end, route health score 54/100. The airports section above carries the live status and delay window at both ends.
How long is the flight from LHR to TFU?
Great-circle distance is 8,354 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 LHR–TFU fly?
Air China runs the route with about 3 flights a week (tue, 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 LHR and arrival-side delay at TFU, 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.
