Boeing's star aircraft in recent years has been the 737 MAX, but the plane has endured one difficulty after another, culminating with a major in-flight safety incident in January 2024. Boeing had been eyeing a ramp-up of MAX production through 2025, but that plan has now been frozen by the Federal Aviation Administration. Alaska Airlines, which until now has been exclusively supplied by Boeing, had been considering orders of the Boeing 737 MAX 10 prior to the January 5 incident. American Airlines CEO Robert Isom last month said Boeing "needs to get their act together," while noting the carrier has large fleets of Airbus and Boeing planes. Besides questions about quality control following the Alaska Airlines incident on the 737 MAX 9, Boeing has yet to receive certification on the 737 MAX 7 and the 737 MAX 10 -- the smallest and largest versions of the single-aisle model.
