Federal Express announced on Monday that its FedEx Express unit exercised options from a 2006 purchase agreement, to buy 15 more Boeing 777 freighters, worth US$3.75 billion at list prices, Although the move clearly bucks the current economic trouble, the express carrier did defer delivery of some of the planes with four B777s slated for delivery in FedEx’s fiscal 2010, four in fiscal 2011, three in each subsequent fiscal year until fiscal 2018, and the remaining one in fiscal 2019. The express carrier now has 30 of Boeing’s 777 Freighters on order, and holds an option to purchase a further 15.
