DEL to SFO questions

Is DEL–SFO running on time right now?

Smooth skies ahead. Both endpoints currently score the same, route health score 100/100. The airports section above carries the live status and delay window at both ends.

How long is the flight from DEL to SFO?

Great-circle distance is 12,381 km. With typical jet cruise speed plus taxi, climb and descent, expect roughly 904–1091 min gate-to-gate on this route.

How often does DEL–SFO fly?

Air India runs the route with about 9 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 DEL and arrival-side delay at SFO, 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.
