ZAG to KOS questions

Is ZAG–KOS running on time right now?

Mostly on schedule. The departure side at ZAG is the weaker end, route health score 78/100. The airports section above carries the live status and delay window at both ends.

How long is the flight from ZAG to KOS?

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 ZAG–KOS 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 ZAG and arrival-side delay at KOS, 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.
