What expedited service means in shipping
In shipping, expedited service means moving a shipment faster than the standard service would. For freight, that usually means a truck or van that carries only your shipment straight to the delivery. It can also mean a booked flight with trucks at each end. Standard service, by contrast, shares space and follows a network schedule.
The term is also used for passports and government filings, which are separate services handled by those agencies. This page covers freight.
