ADD to NBJ questions
How long is the flight from ADD to NBJ?
Great-circle distance is 3,445 km. With typical jet cruise speed plus taxi, climb and descent, expect roughly 273–325 min gate-to-gate on this route.
How often does ADD–NBJ fly?
Ethiopian Airlines runs the route with about 7 flights a week (daily). 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 ADD and arrival-side delay at NBJ, 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.
