LHR to SAN questions
Is LHR–SAN running on time right now?
Smooth skies ahead. The departure side at LHR is the weaker end, route health score 89/100. The airports section above carries the live status and delay window at both ends.
How long is the flight from LHR to SAN?
Great-circle distance is 8,806 km. With typical jet cruise speed plus taxi, climb and descent, expect roughly 652–785 min gate-to-gate on this route.
How often does LHR–SAN fly?
British Airways runs the route with about 14 flights a week (daily). 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 SAN, 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.
