1 empty leg flight from Sacramento to San Diego this month from 1 operator, updated Oct 3. About 388 nm, roughly 1h 16m 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 Sacramento and needs it near
San Diego, 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.
