How the Bilbao to Zurich route actually runs
Pro Flight Search records official board updates for nonstop BIO to ZRH flights through the day: schedules, estimates, gate pushes and actual departures. The verdict above comes from operated flights, so it reflects what this route does rather than what the timetable promises.

BIO to ZRH questions
Is BIO–ZRH 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 BIO to ZRH?
Great-circle distance is 1,006 km. With typical jet cruise speed plus taxi, climb and descent, expect roughly 101–116 min gate-to-gate on this route.
How often does BIO–ZRH fly?
Edelweiss Air runs the route with about 4 flights a week (sun, mon, tue, thu). 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 BIO and arrival-side delay at ZRH, 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.
