Abstract: The embodiments relate to systems and methods for conducting an electronic auction for available cargo capacity on a cargo carrier. In one aspect, the embodiments may monitor the cargo carrier to determine its geographic location as the cargo carrier travels towards a starting point of a route; determine a route starting distance between the geographic location of the cargo carrier and the starting point of the route; begin the electronic auction to sell the available cargo capacity prior to the cargo carrier arriving at the starting point of the route, the electronic auction selling the available cargo capacity at a current route price that corresponds to the route starting distance; and receive input indicating a purchase of the available cargo capacity at the current route price. In some embodiments, a route may be partitioned into potentially overlapping segments, and electronic auctions may be conducted for each route segment.
