The airline says in a statement it has signed an agreement with Airbus to purchase 10 A330-200s for delivery from March 2010 to August 2012.
It says each aircraft, including engines, is worth around $170 million and China Southern will pay for the aircraft in cash and bank financing.
The statement fails to mention the engine type but according to Flight’s ACAS database Rolls-Royce powers the six A330-200s already in the airline’s fleet and until now the airline has had no A330-200s on order.
Even though China Southern has signed an agreement, the airline says the purchase is subject to approval from shareholders and China’s government.
The 10 A330-200s are needed to “improve the company’s operating capacity in order to accommodate the continuous growth in demand for aviation services” in China, it adds.
