PRG to ZAG questions
Is PRG–ZAG running on time right now?
Smooth skies ahead. The arrival side at ZAG is the weaker end, route health score 88/100. The airports section above carries the live status and delay window at both ends.
How long is the flight from PRG to ZAG?
Great-circle distance is 503 km. With typical jet cruise speed plus taxi, climb and descent, expect roughly 66–73 min gate-to-gate on this route.
How often does PRG–ZAG fly?
Croatia Airlines runs the route with about 2 flights a week (mon, 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 PRG 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.
