DUB to JER questions
Is DUB–JER running on time right now?
Smooth skies ahead. The departure side at DUB 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 DUB to JER?
Great-circle distance is 547 km. With typical jet cruise speed plus taxi, climb and descent, expect roughly 69–77 min gate-to-gate on this route.
How often does DUB–JER fly?
Aer Lingus runs the route with about 4 flights a week (mon, wed, fri, sat). 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 DUB and arrival-side delay at JER, 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.
