United Airlines today announced an order for 150 Boeing 737 planes to upgrade its narrowbody fleet. The order includes 100 of Boeing’s new 737 Max planes. According to the press release, United will be the North American launch customer for Boeing 737 Max 9 aircraft. The deliveries will start in 2018.
Boeing 737 Max is the tweaked variant of the companies best selling 737 narrowbody jetliner, offering better fuel economy. Boeing originally planned to replace the aging 737 workhorse with a new design from the ground up (like it did for the 787 dreamliner). Instead, Boeing decided to modify the existing platform to bring an upgraded product to the market sooner, because of the success of a similar strategy employed by its competitor Airbus with its A320 neo.
Going by the orders it is getting for the new 737s, it looks like Boeing made the right call.
