How the Singapore to Naha route actually runs
Pro Flight Search records official board updates for nonstop SIN to OKA 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.

SIN to OKA questions
Is SIN–OKA running on time right now?
Mostly on schedule. The departure side at SIN is the weaker end, route health score 73/100. The airports section above carries the live status and delay window at both ends.
How long is the flight from SIN to OKA?
Great-circle distance is 3,746 km. With typical jet cruise speed plus taxi, climb and descent, expect roughly 294–351 min gate-to-gate on this route.
How often does SIN–OKA fly?
Scoot runs the route with about 4 flights a week (sun, mon, wed, 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 SIN and arrival-side delay at OKA, 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.
