RKS to SLC questions
Is RKS–SLC running on time right now?
Smooth skies ahead. Both endpoints currently score the same, route health score 100/100. The airports section above carries the live status and delay window at both ends.
How long is the flight from RKS to SLC?
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 RKS–SLC 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 RKS and arrival-side delay at SLC, 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.
