SJU to RDU questions

Is SJU–RDU running on time right now?

Smooth skies ahead. The departure side at SJU 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 SJU to RDU?

Great-circle distance is 2,310 km. With typical jet cruise speed plus taxi, climb and descent, expect roughly 193–228 min gate-to-gate on this route.

How often does SJU–RDU fly?

JetBlue Airways runs the route with about 5 flights a week (sun, mon, thu, 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 SJU and arrival-side delay at RDU, 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.
