The logistics of FedEx overnight service are similar, and even more complicated in some respects: A package enters the system from any of bajillions of locations around the country/world (many more than there are airports), including FedEx stores, residential homes, major businesses, and random convenience store parters. The package makes at least half a dozen stops with incredibly tight connection times, traveling by land and air. Sometime deliveries are canceled or re-directed while en route. Yet FedEx seems to have a way lower rate of missing packages.
