Boeing's 2026 Commercial Market Outlook forecasts that operators worldwide will need nearly 44,000 new airplanes over the next 20 years to support air travel and cargo growth. The projection breaks down to 33,545 single-aisle jets, 7,715 widebodies, 1,435 regional aircraft, and 930 freighters, totaling 43,625 new deliveries.

The global commercial fleet is expected to grow nearly 80 percent to more than 50,000 airplanes by 2045 as airlines and cargo carriers add capacity and passenger demand doubles. Boeing projects that half of the deliveries will replace older aircraft with more fuel-efficient models, while the single-aisle narrowbody fleet grows to more than 36,000 aircraft.

The forecast carries direct weight for the maintenance sector. A fleet of that size, weighted toward high-utilization narrowbody jets, generates sustained demand for checks, component overhauls, and engine work across the service life of each aircraft. US carriers and repair stations sit among the largest operators of the single-aisle fleet that dominates the outlook.

On the freight side, Boeing forecasts air cargo traffic to grow about 3.7 percent annually through 2045, outpacing broader trade and economic growth. Low-cost carrier fleets are projected to expand nearly 4 percent per year, ahead of the roughly 3 percent growth expected for network carriers.

Boeing said near-term disruptions are not expected to meaningfully change the long-term growth trajectory for commercial aviation.
