LUM to TFU questions

How long is the flight from LUM to TFU?

Great-circle distance is 879 km. With typical jet cruise speed plus taxi, climb and descent, expect roughly 92–105 min gate-to-gate on this route.

How often does LUM–TFU fly?

4 carriers operate this route, around 35 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 LUM and arrival-side delay at TFU, 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.
