CVG to RDU questions
Is CVG–RDU running on time right now?
Smooth skies ahead. The departure side at CVG 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 CVG to RDU?
Great-circle distance is 627 km. With typical jet cruise speed plus taxi, climb and descent, expect roughly 74–84 min gate-to-gate on this route.
How often does CVG–RDU fly?
Delta Air Lines runs the route with about 6 flights a week (sun, mon, tue, wed, thu, 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 CVG 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.
