Boeing's 2024 deliveries fell by about a third from a year earlier to 348 airplanes. The company's delivery gap with rival Airbus widened as the European plane maker handed over 766 jetliners. Boeing struggled to ramp up production and deliveries due to a midair door plug blowout in January 2024 and then a machinist strike in the fall.

Boeing must turn its fortunes around this year to avoid falling further behind Airbus, which plans a production increase as it fixes its supply chain.

Boeing commercial jet deliveries dropped last year by more than a third compared to 2023, as the aerospace giant wrestled with multiple major challenges. In data released Tuesday, Boeing (NYSE: BA) reported it delivered 348 airplanes to customers in 2024, down from 528 the year prior.
