LHR to SLC questions

Is LHR–SLC running on time right now?

Some delays possible. The departure side at LHR is the weaker end, route health score 67/100. The airports section above carries the live status and delay window at both ends.

How long is the flight from LHR to SLC?

Great-circle distance is 7,810 km. With typical jet cruise speed plus taxi, climb and descent, expect roughly 581–699 min gate-to-gate on this route.

How often does LHR–SLC fly?

Delta Air Lines runs the route with about 5 flights a week (sun, tue, wed, 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 SLC, 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.
