"In June 2011 AirAsia ordered 200 Airbus A320neo's at the Paris Air Show. This is the largest single order in commercial aviation history. The planes are due to become available in 2015, and the deal is the largest number of commercial aircraft ordered in history. The deal was worth $18 billion at list prices, although it is likely that AirAsia would have gotten a substantial discount from those prices. Singapore based analyst Shukor Yusof said the deal had the potential to rival American Southwest Airlines and make Air Asia the world's biggest low cost aircraft carrier. The deal makes AirAsia Airbus' single biggest customer."
