ZAG to BRU questions
Is ZAG–BRU running on time right now?
Smooth skies ahead. The departure side at ZAG is the weaker end, route health score 96/100. The airports section above carries the live status and delay window at both ends.
How long is the flight from ZAG to BRU?
Great-circle distance is 1,029 km. With typical jet cruise speed plus taxi, climb and descent, expect roughly 103–118 min gate-to-gate on this route.
How often does ZAG–BRU fly?
Croatia Airlines runs the route with about 11 flights a week (sun, mon, tue, wed, thu, fri). 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 ZAG and arrival-side delay at BRU, 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.
