DEL to LHR questions
Is DEL–LHR running on time right now?
Smooth skies ahead. The arrival side at LHR is the weaker end, route health score 88/100. The airports section above carries the live status and delay window at both ends.
How long is the flight from DEL to LHR?
Great-circle distance is 6,731 km. With typical jet cruise speed plus taxi, climb and descent, expect roughly 505–607 min gate-to-gate on this route.
How often does DEL–LHR fly?
4 carriers operate this route, around 66 flights a week between them. Compare carrier days and times in the airline list above.
What does the route health score measure?
A blend of departure-side delay at DEL 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.
