How the Preah Sihanouk to Jakarta route actually runs

KOS to CGK questions
Is KOS–CGK 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 KOS to CGK?
Great-circle distance is 1,887 km. With typical jet cruise speed plus taxi, climb and descent, expect roughly 163–192 min gate-to-gate on this route.
How often does KOS–CGK fly?
LION AIRLINES runs the route with about 1 flight a week (thu). 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 KOS and arrival-side delay at CGK, 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.
