SEATTLE, Dec. 19, 2012 / PRNewswire / -- Boeing [NYSE: BA] and FedEx Express, a wholly owned subsidiary of FedEx Corp., today announced an order for four 767 Freighters. The order is part of FedEx's initiative to modernize its fleet. "These additional 767 orders will help accelerate our fleet modernization program as we replace our aging MD-10 freighter fleet," said James R. Parker, FedEx Express executive vice president, air operations. "These new 767s will provide significantly improved reliability and are substantially more fuel-efficient than the aircraft they will replace. They will be an excellent addition to the FedEx fleet."
