Boeing expects global demand for air travel to increase by more than 40% by 2030, driving the need for thousands of new jetliners in the next few years, according to its 20-year demand forecast for commercial airliners released Sunday ahead of the Paris Airshow.

The company expects demand for 43,600 new airliners through 2044. That is essentially the same as last year's edition, which projected demand for 43,975 new deliveries through 2043.
