FARNBOROUGH, England (Reuters) - AirAsia Group expanded an order for A330neo passenger jets, adding 34 aircraft to an existing order to bring the total to 100 long-haul wide-body jets worth $30 billion at list prices.

The budget carrier's AirAsia X long-haul unit announced the deal, which includes a long-awaited confirmation of an order for 66 planes, at the Farnborough Airshow. The deal follows a fierce contest between Airbus and Boeing BA.N after AirAsia threatened to defect to the Boeing 787 model.
