Nothing on this route today? Widen out: every empty leg across Seattle.
North Bend to Seattle is a different flight with its own aircraft, its own days and its own price: empty legs from North Bend to Seattle.
Nobody schedules an empty leg. One shows up here because an operator has an aircraft finishing a trip near Seattle and needs it near North Bend — 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.
