SLC to RKS questions
Is SLC–RKS running on time right now?
Smooth skies ahead. The departure side at SLC is the weaker end, route health score 84/100. The airports section above carries the live status and delay window at both ends.
How long is the flight from SLC to RKS?
Great-circle distance is 260 km. With typical jet cruise speed plus taxi, climb and descent, expect roughly 48–52 min gate-to-gate on this route.
How often does SLC–RKS fly?
Alpine Air Express runs the route with about 5 flights a week (mon–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 SLC and arrival-side delay at RKS, 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.
