GUM to FUK questions
Is GUM–FUK running on time right now?
Smooth skies ahead. The arrival side at FUK is the weaker end, route health score 92/100. The airports section above carries the live status and delay window at both ends.
How long is the flight from GUM to FUK?
Great-circle distance is 2,664 km. With typical jet cruise speed plus taxi, climb and descent, expect roughly 218–258 min gate-to-gate on this route.
How often does GUM–FUK fly?
T'Way Air runs the route with about 2 flights a week (tue, wed). 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 GUM and arrival-side delay at FUK, 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.
