Pro Flight Search records official board updates for nonstop LHR to MRS 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.
Significant delay risk. The departure side at LHR is the weaker end, route health score 46/100. The airports section above carries the live status and delay window at both ends.
How long is the flight from LHR to MRS?
Great-circle distance is 990 km. With typical jet cruise speed plus taxi, climb and descent, expect roughly 100–115 min gate-to-gate on this route.
How often does LHR–MRS fly?
British Airways runs the route with about 41 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 MRS, 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.
