During the next 20 years, Boeing expects about 51% of demand for new aircraft to come from growth rather than replacing older airplanes. China and South/Southeast Asia, which includes India, are expected to account for half of that additional capacity, according to the outlook. North America and Eurasia account for more than half of projected deliveries for replacing older aircraft. China makes up an estimated 10% of Boeing's existing order backlog. The country paused taking delivery of new Boeing aircraft as China and the U.S. clashed over tariffs. However, deliveries are expected to resume this month, Ortberg said in May during an investors conference.
