US delivery giant FedEx said Wednesday it expects its busiest day in company history with some 22 million shipments around the world on "Cyber Monday" which falls December 2.

FedEx said it anticipates that during the week of December 1-7, the busiest week for delivery of holiday shopping items, it expects more than 85 million shipments to move through its global networks, a 13 percent increase from a year ago,

FedEx said personal consumer electronics, apparel and luxury goods will drive this increase for Cyber Monday, which marks the traditional start in the United States of year-end holiday shopping.

"Our workforce of more than 300,000 team members worldwide is ready to deliver the holidays once again this year," said Frederick Smith, chairman and chief executive of FedEx.

The company, which updated its quarterly guidance, said it would increase its workforce with tens of thousands of seasonal positions to help handle the surge.

The National Retail Federation expects US holiday sales are expected to grow 3.9 percent to $602 billion.

Research firm eMarketer said it projects online holiday sales would jump 15.1 percent year-over-year to $61.8 billion.
