INI to LJU questions
Is INI–LJU 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 INI to LJU?
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 INI–LJU 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 INI and arrival-side delay at LJU, 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.
