Fractional-share provider NetJets has ordered up to 425 Bombardier and Cessna jets worth as much as $9.6 billion, with deliveries to begin in 2015. The purchase is the largest general aviation aircraft order in history and includes a firm order for 75 Bombardier Challenger 300s (plus options on another 125), a firm order for 25 Challenger 605s (plus options on 50 more) and a firm order for 25 Cessna Citation Latitudes (plus options on an additional 125). Deliveries begin in 2014 for the 300s, 2015 for the 605s and 2016 for the Latitudes. The Bombardier order is worth up to $7.3 billion and the Cessna order up to $2.3 billion. Those are retail prices and also the totals if NetJets exercises all of its options. NetJets will likely pay less than retail, but chairman and CEO Jordan Hansell explained, “We don’t get into specifics of our contractual relationship with folks, so all we’re willing to say at this point is that the $9.6 billion is list [pricing].”
