How the Tokyo to Houston route actually runs
Pro Flight Search records official board updates for nonstop HND to IAH 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.

HND to IAH questions
Is HND–IAH running on time right now?
Smooth skies ahead. The departure side at HND is the weaker end, route health score 95/100. The airports section above carries the live status and delay window at both ends.
How long is the flight from HND to IAH?
Great-circle distance is 10,725 km. With typical jet cruise speed plus taxi, climb and descent, expect roughly 787–949 min gate-to-gate on this route.
How often does HND–IAH fly?
All Nippon Airways 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 HND and arrival-side delay at IAH, 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.
