In 2010, Airbus said it was making the Airbus A320neo family, which is an improved version of the Airbus A320 family. Airlines started ordering a lot of A320neos. AirAsia and IndiGo are examples. This made Boeing's managers allow the 737 MAX to be developed on August 30, 2011. Boeing said that the 737 MAX will use 16% less fuel than the Airbus A320 and 4% less than the Airbus A320neo. Boeing thinks the 737 MAX will be able to fly farther than Airbus A320neo. The first 737 MAX aircraft is supposed to be delivered in 2017.
