LHR to PIT questions

Is LHR–PIT running on time right now?

Mostly on schedule. The departure side at LHR is the weaker end, route health score 77/100. The airports section above carries the live status and delay window at both ends.

How long is the flight from LHR to PIT?

Great-circle distance is 5,970 km. With typical jet cruise speed plus taxi, climb and descent, expect roughly 451–542 min gate-to-gate on this route.

How often does LHR–PIT fly?

British Airways runs the route with about 7 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 PIT, 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.
