Because they employ their own planes, have vast ground networks, and have accurate, real-time tracking systems, integrated carriers such as UPS and Federal Express are able to acquire a larger market share.
UPS is the world's leading domestic and international package delivery firm and a ShipEngine fully integrated partner.
FedEx Express, a division of FedEx Corporation, is a large American cargo airline headquartered in Memphis, Tennessee. It is one among the world's largest airlines in terms of fleet size and freight tonnage flown as of 2020.
