United Parcel Service (UPS) celebrated its 100th anniversary in 2007 and is the world's largest package delivery company and a leader in supply chain services. Offering an extensive range of options for managing the movement of goods, information and funds, it is headquartered in Atlanta, serves more than 200 territories, is the 9th largest airline in the world with nearly 300 aircraft and has just under 100,000 vehicles in its delivery fleet. It has been quick to take advantage of emerging opportunities over the years. Its first air-express flights started in 1929 and an intercontinental service between the US and Europe was launched in 1975. The UPS website has proved to be a vital platform for growth and now provides 15 million customers a day with on-line tracking. While its primary business is the time-definite delivery of packages and documents, UPS has also extended its capabilities to encompass a broader spectrum of services.
