KOS to ZAG questions
Is KOS–ZAG running on time right now?
Smooth skies ahead. The arrival side at ZAG is the weaker end, route health score 92/100. The airports section above carries the live status and delay window at both ends.
How long is the flight from KOS to ZAG?
Great-circle distance is 8,980 km. With typical jet cruise speed plus taxi, climb and descent, expect roughly 664–800 min gate-to-gate on this route.
How often does KOS–ZAG fly?
Ryanair runs the route with about 3 flights a week (mon, 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 KOS and arrival-side delay at ZAG, 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.
