2 empty leg flights from Fort Lauderdale to Knoxville/Maryville live now from 2 operators, updated Oct 25. About 617 nm, roughly 1h 49m 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 Fort Lauderdale and needs it near
Knoxville/Maryville, 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.
