ANC to ADK questions
Is ANC–ADK running on time right now?
Mostly on schedule. The departure side at ANC is the weaker end, route health score 78/100. The airports section above carries the live status and delay window at both ends.
How long is the flight from ANC to ADK?
Great-circle distance is 1,913 km. With typical jet cruise speed plus taxi, climb and descent, expect roughly 165–194 min gate-to-gate on this route.
How often does ANC–ADK fly?
Alaska Airlines runs the route with about 2 flights a week (wed, 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 ANC and arrival-side delay at ADK, 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.
