NCE to IAD questions
Is NCE–IAD running on time right now?
Mostly on schedule. The departure side at NCE is the weaker end, route health score 77/100. The airports section above carries the live status and delay window at both ends.
How long is the flight from NCE to IAD?
Great-circle distance is 6,773 km. With typical jet cruise speed plus taxi, climb and descent, expect roughly 508–611 min gate-to-gate on this route.
How often does NCE–IAD fly?
United Airlines runs the route with about 4 flights a week (sun, mon, wed, 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 NCE and arrival-side delay at IAD, 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.
