Boeing’s campaign to restore the reputation of its best-selling plane after two deadly crashes suffered a blow with a Saudi airline canceling an order worth up to $5.9 billion in favor of a European rival of the U.S. manufacturer. Flyadeal, the budget airline arm of Saudi Arabian Airlines Corp., ordered 30 A320neo jets from Airbus and took options on 20 more, meaning that its entire fleet will consist of planes from that company. It’s a potentially troubling sign for Boeing, which has not seen customers divert orders to Airbus en masse.
