5 empty leg flights from Portland to San Diego in the last 90 days, updated Oct 23. About 787 nm, roughly 2h 13m in a midsize jet. Nothing live on this exact route this minute. Save the route and we will watch it for you.
Nobody schedules an empty leg. One shows up here because an
operator has an aircraft finishing a trip near Portland 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.
