Since the system was first launched in the summer of 1998 as a freight tracking system, new functions have been added to it to meet Alliance Air’s business requirements in its cargo ground handling service and road feeder service for its client airlines. Today, in addition to the original freight tracking and EDI messaging processes, 3ATrack also has the capability to act as a warehouse management system, yield management system, and airline cargo reservation system.
