Dead head flights is a private aviation industry term referring to a leg of a trip that transports zero passengers.  Typically, this occurs upon return from dropping off passengers or repositioning to pick up passengers.  Because this type of flight rarely generates any profits for the airline, some charter companies offer these “empty legs” at a fraction of the regular price to offset operational costs.  For the passenger, this often comes at the cost of flexibility and access to the most desired flight destination.  This term may also describe carrying members of company’s flight crew when they are not working.  This can occur when the crew needs to be positioned to another location for work purposes.  Dead head flights are also referred to as ‘empty leg’, ‘positioning’, or ‘dead-heading.’
