The U.S. planemaker's forecast was almost identical to its 2025 outlook. Boeing forecast industry-wide global deliveries of 43,625 new jetliners and freighters around the world from 2026 through 2045 -- 33,545 single-aisle jets, 7,715 widebody aircraft, 930 factory-built freighters and 1,435 regional jets.
This month, Boeing's European rival Airbus trimmed its projection by 1% to 42,060 new aircraft, citing the Iran war and trade tensions.
Boeing expects air passenger traffic growth of about 2.3% this year, less than half of last year's growth rate of 5.3%. It expects growth to rebound to 6%-7% in 2027 and 5%-6% in 2028.
"Our outlook is that passenger traffic globally will be where it would have been by the end of 2028," Boeing Commercial Marketing Vice President Darren Hulst told reporters. He described the current slowdown as different from the multi-year demand shock caused by the COVID-19 pandemic.
Boeing expects passenger traffic to grow 4% annually over the next 20 years, with cargo traffic rising 3.7%, the jet fleet expanding 3% and the world economy growing 2.5%.
Demand for new aircraft continues to grow faster than planemakers can deliver new jets. Passenger traffic last year had rebounded to pre-pandemic levels, but deliveries of new jets remained below the 2018 output, Hulst said.
The company estimates an undersupply of close to 2,000 aircraft entering 2026, with the single-aisle shortfall unlikely to clear until around the end of the decade and widebody shortages likely to persist into the early 2030s.
The outlook assumes a roughly even split between replacement and growth demand. Boeing projects 21,475 deliveries will replace older jets and 22,150 will support fleet expansion. The global fleet is expected to rise from about 28,000 aircraft in 2025 to 50,000 by 2045, with new-generation aircraft growing from 32% of the fleet to 92%.
China is expected to account for 21% of deliveries, followed by Eurasia at 20%, North America and South/Southeast Asia at 19% each, the Middle East and Africa at 10%, Latin America at 6% and Oceania/Northeast Asia at 5%.
Boeing's forecast reflects a market recovering from repeated shocks but still constrained by manufacturing capacity and supply-chain fragility. Boeing also faces certification delays on key programs including the 737 MAX 7 and 10 and the 777-9.
Hulst said the long-term demand picture remains supported by trade, tourism, migration and airline network expansion.
"The reason why we travel and the reason why goods move isn't changing," he said.
