Due to Idris Jala's appointment to the cabinet in August 2009, Tengku Azmil Zahruddin took over as the airline's new CEO. In December that year, MAS announced the purchase of 15 new Airbus A330 aircraft, with options for another 10. Expected to be delivered between 2011 and 2016, they are intended to operate on medium-haul routes to eastern Asia, Australia, and the Middle East. The airline's plans are to run the Airbus A380 planes, which were then introduced into service in 2012, on long-haul routes, the A330s on medium-haul routes, and Boeing 737 aircraft on short-haul routes.
