LJU to INI questions

Is LJU–INI running on time right now?

Mostly on schedule. The departure side at LJU is the weaker end, route health score 74/100. The airports section above carries the live status and delay window at both ends.

How long is the flight from LJU to INI?

Great-circle distance is 666 km. With typical jet cruise speed plus taxi, climb and descent, expect roughly 77–87 min gate-to-gate on this route.

How often does LJU–INI fly?

Air Serbia runs the route with about 2 flights a week (tue, 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 LJU and arrival-side delay at INI, 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.
