How the Nagasaki to Tokyo route actually runs
Pro Flight Search records official board updates for nonstop NGS to NRT 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.

NGS to NRT questions
Is NGS–NRT 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 NGS to NRT?
Great-circle distance is 1,012 km. With typical jet cruise speed plus taxi, climb and descent, expect roughly 101–117 min gate-to-gate on this route.
How often does NGS–NRT fly?
Jetstar Japan runs the route with about 7 flights a week (daily). 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 NGS and arrival-side delay at NRT, 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.
