WHAT’S AND EMPTY LEG FLIGHT?
An empty leg is a flight that becomes available during the reposition of an aircraft, flying empty to start its next booked route or just return to base.
The short notice is explained because they usually present themselves after a client books a one-way flight, thus if that booking is made for the same day, that leaves only a few hours to offer the empty leg. But that’s an extreme case and generally you will have between one or three days to decide if that fixed route and time go in hand with your travel needs.
The previous explains why empty leg flights are sold at a discounted price, sometimes up to 70% less than the standard amount for the same route. The aforementioned lack of time prevents operators from finding a full-price customer that, first, wants the same plane, second, that specific route and third, that day and time.
