Worldport is the worldwide air hub for UPS (United Parcel Service) located at the Louisville International Airport in Louisville, Kentucky. Although UPS has had a hub at Louisville since 1980, the term was not used officially by the company until 2002, after a $1 billion, five-year expansion. Previously, the project was named Hub 2000. The facility is currently the size of 80 football fields and capable of handling 115 packages a second, or 416,000 per hour. With over 20,000 employees, UPS is one of the largest employers in Louisville, and in the Commonwealth of Kentucky. The facility mainly handles express and international packages and letters. Worldport serves all major domestic and international hubs.
