How the Cairns to Perth route actually runs
Pro Flight Search records official board updates for nonstop CNS to PER flights through the day: schedules, estimates, gate pushes and actual departures. The verdict above comes from operated flights, so it reflects what this route does rather than what the timetable promises.

CNS to PER questions
Is CNS–PER 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 CNS to PER?
Great-circle distance is 3,432 km. With typical jet cruise speed plus taxi, climb and descent, expect roughly 272–324 min gate-to-gate on this route.
How often does CNS–PER fly?
Jetstar Airways runs the route with about 4 flights a week (mon, wed, fri, 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 CNS and arrival-side delay at PER, 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.
