1 empty leg flight from Denver to Boise this month from 1 operator, updated Oct 23. About 564 nm, roughly 1h 42m in a midsize jet. 1 leg live on this route right now.
Nobody schedules an empty leg. One shows up here because an
operator has an aircraft finishing a trip near Denver and needs it near
Boise, or needs it home and this direction happens to be the way home.
That is why the flight can be a fraction of a full charter, why it can
vanish within hours, and why the return direction is a different flight
entirely with its own price and its own aircraft. Watching the route beats
searching it once.
