KEF to LJU questions
Is KEF–LJU running on time right now?
Mostly on schedule. The departure side at KEF is the weaker end, route health score 79/100. The airports section above carries the live status and delay window at both ends.
How long is the flight from KEF to LJU?
Great-circle distance is 3,002 km. With typical jet cruise speed plus taxi, climb and descent, expect roughly 242–287 min gate-to-gate on this route.
How often does KEF–LJU fly?
Trade Air runs the route with about 2 flights a week (tue, 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 KEF and arrival-side delay at LJU, 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.
