Boeing edged out Airbus to claim a sales victory at the Farnborough air show as its European rival failed to land an anticipated 100-jet order amid a flurry of late deals at the year’s biggest aviation expo. The U.S. company ended the show Thursday after booking new business worth $79 billion from orders and outline commitments involving 528 jetliners, according to its closing statement at the trade fair southwest of London. Airbus said it racked up $62 billion of sales from 431 planes, meaning the hoped-for order for A321neo narrow-body planes from AirAsia Group would have given it victory by a margin of just three jets.
