Deliveries of new Boeing jets bounced back in December after a crippling labor strike that slowed production last fall, but the company’s annual deliveries dropped in 2024 to the lowest level since the COVID-19 pandemic. The company said on Tuesday that it delivered 348 commercial jets last year, down from 528 the previous year. New orders for jets in 2024 dropped to less than half as many as Boeing recorded one year earlier.
