KUL to SRG questions
Is KUL–SRG running on time right now?
Mostly on schedule. The departure side at KUL is the weaker end, route health score 74/100. The airports section above carries the live status and delay window at both ends.
How long is the flight from KUL to SRG?
Great-circle distance is 1,447 km. With typical jet cruise speed plus taxi, climb and descent, expect roughly 132–154 min gate-to-gate on this route.
How often does KUL–SRG fly?
AirAsia runs the route with about 3 flights a week (wed, thu, 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 KUL and arrival-side delay at SRG, 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.
