SAI to CCU questions

Is SAI–CCU 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 SAI to CCU?

Great-circle distance is 1,959 km. With typical jet cruise speed plus taxi, climb and descent, expect roughly 168–198 min gate-to-gate on this route.

How often does SAI–CCU fly?

IndiGo runs the route with about 3 flights a week (mon, 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 SAI and arrival-side delay at CCU, 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.
