TFU to KTM questions
Morning or evening flight on TFU–KTM?
Operators schedule morning departures around 09:05 from TFU. Earlier flights typically land before destination-airport delays accumulate later in the day; check the KTM delay card to confirm conditions when you'd arrive.
How long is the flight from TFU to KTM?
Great-circle distance is 1,876 km. With typical jet cruise speed plus taxi, climb and descent, expect roughly 162–191 min gate-to-gate on this route.
How often does TFU–KTM fly?
2 carriers operate this route, around 12 flights a week between them. Compare carrier days and times in the airline list above.
What does the route health score measure?
A blend of departure-side delay at TFU and arrival-side delay at KTM, 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.
