GCM to LHR questions
Is GCM–LHR running on time right now?
High disruption likely. The arrival side at LHR is the weaker end, route health score 0/100. The airports section above carries the live status and delay window at both ends.
How long is the flight from GCM to LHR?
Great-circle distance is 7,719 km. With typical jet cruise speed plus taxi, climb and descent, expect roughly 575–692 min gate-to-gate on this route.
How often does GCM–LHR fly?
British Airways runs the route with about 6 flights a week (sun, tue, wed, thu, fri, 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 GCM and arrival-side delay at LHR, 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.
