Once written off as dead, the converted 747 freighters have shown new life over the last nine months, Dimitroff said. Airlines switched long-range flying to more economical twin-engine models, and Boeing last year dropped the 747 from its long-term forecast for passenger planes. United Parcel Service Inc. negotiated a freighter order that will keep Boeing’s 747-8 assembly line open into the next decade. That bodes well for all-new Boeing freighters, as well as for the used models. Boeing no longer retrofits the planes to haul packages instead of people, makeovers that used to cost as much as $30 million.
