Answered it myself-I think!????
"Line haul logistics refers to the movement of freight or goods across different modes of transport by land, air, waterway, between distant cities, ports or even warehouses. While the routes are fixed, the goods transported can vary in volume and weight, from small documents to heavy pallets."
But I would have thought that would come before: "Departed from Sortation Center Your parcel is on the way to the last mile hub for delivery."?
