Airbus boosts production of its widebody A350 jets from six to nine a month by 2025. The smaller 330neo will go from three to four a month. Both Airbus and Boeing have difficulties increasing production with an overstretched supply chain. Both airplane makers have late deliveries to customers. Boing is having problems increasing production of the 787 with the goal of making five a month shifted to the end of the year. The 777X aircraft the biggest to order is years behind in its development schedule.
