IAD to RUH questions
Is IAD–RUH running on time right now?
High disruption likely. The departure side at IAD is the weaker end, route health score 0/100. The airports section above carries the live status and delay window at both ends.
How long is the flight from IAD to RUH?
Great-circle distance is 10,842 km. With typical jet cruise speed plus taxi, climb and descent, expect roughly 795–959 min gate-to-gate on this route.
How often does IAD–RUH fly?
Saudi Arabian runs the route with about 5 flights a week (sun, mon, wed, 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 IAD and arrival-side delay at RUH, 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.
