ADD to ZNZ questions
Morning or evening flight on ADD–ZNZ?
Operators schedule morning departures around 08:20 and evening departures around 23:55 from ADD. Earlier flights typically land before destination-airport delays accumulate later in the day; check the ZNZ delay card to confirm conditions when you'd arrive.
How long is the flight from ADD to ZNZ?
Great-circle distance is 1,691 km. With typical jet cruise speed plus taxi, climb and descent, expect roughly 149–175 min gate-to-gate on this route.
How often does ADD–ZNZ fly?
Ethiopian Airlines runs the route with about 18 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 ZNZ, 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.
