Business jet buyers are expected to take delivery of as many as 675 new aircraft worth about $20.5 billion this year, a slight rise over deliveries worth $20 billion 2013, according to a forecast by Honeywell International Inc (HON.N). Corporate fleet managers, including governments and charter companies, plan to make new jet purchases over the next five years equal to, on average, about 23 percent of their fleets, down from about 28 percent in the 2013 survey, Honeywell said.
