In the 22 months that Boeing’s 737 Max flew commercially before it was grounded, the jet became the company’s flagship as well as an integral part of the global aviation system, and the American economy.
Airlines around the world sped the plane into service, eager to capitalize on its efficient engines. Some low-cost carriers built new routes around the Max, which could travel farther on less fuel than its predecessor. Boeing’s stock soared thanks to strong demand for the jet.
