1 empty leg flight from Boston to Palm Beach this month from 2 operators, updated Oct 23. About 1,059 nm, roughly 2h 52m in a midsize jet. 2 legs 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 Boston and needs it near
Palm Beach, 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.
