SJU to CUR questions
Is SJU–CUR running on time right now?
Smooth skies ahead. The departure side at SJU is the weaker end, route health score 84/100. The airports section above carries the live status and delay window at both ends.
How long is the flight from SJU to CUR?
Great-circle distance is 764 km. With typical jet cruise speed plus taxi, climb and descent, expect roughly 84–95 min gate-to-gate on this route.
How often does SJU–CUR fly?
American Airlines runs the route with about 1 flight a week (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 SJU and arrival-side delay at CUR, 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.
