Which company produces half of the world's jet airliners?

Airbus is recognized for producing a significant portion of the world's jet airliners, and it competes closely with Boeing for market share. The company has established itself as one of the leading manufacturers, with a diverse range of aircraft that cater to both regional and international markets. Airbus's innovative designs and commitment to sustainability have further solidified its position in the aviation industry, enabling it to capture a substantial share of jet airliner production globally.

The other companies mentioned, while also significant players in the aerospace sector, do not match the production scale and market penetration of Airbus in the context of commercial jet airliners. Lockheed Martin, for instance, mainly focuses on military aircraft and advanced technologies, while Embraer produces smaller regional jets and business jets, catering to specific market segments rather than the broad commercial airliner category.
