Dead Mileage is an expression that is used to explain the dead leg of a journey. For example if a journey starts from London and ends at Heathrow Airport the customer is dropped off then the driver returns back home empty so the journey from Heathrow to London is called the Dead Mileage! (Because he is not getting paid to drive back home and is travelling empty)! So Companies/Drivers who list their journies in advance may get a return job which will cut out their Dead Mileage!
