Cathay Pacific said Wednesday it will buy 12 planes from Boeing at a list price of $3.28 billion as part of the airline\'s continuing expansion plans. The Hong Kong-based carrier said it would buy four Boeing 777-300ER passenger aircraft and another eight Boeing 777-200F freighter aircraft for a total list price of $3.28 billion, but added it had won \"significant price concessions\" from the US aircraft maker.
