Peter Hill, CEO of Oman Air has said that Boeing risks losing a $1bn order for its 787 Dreamliner aircraft to a rival model from Airbus, if the US plane's production schedule is delayed any further, Times of Oman has reported. 'Further delays might mean that we'd have to look elsewhere,' he said. The Sultanate's national carrier already has seven A330s from Airbus on order, with the first four scheduled for handover this year.
