Boeing has raised its forecast demand for aircraft to more than 35,000 over the next 20 years. According to its annual Current Market Outlook (CMO) report, the world fleet will double over the next two decades, creating demand for $4.8trn worth of aircraft. "This forecast gives us confidence as we increase our production rates and invest in new products like the 777X and 787-10X," said Randy Tinseth, VP of marketing, Boeing Commercial Airplanes. Both passenger traffic and cargo traffic are predicted to grow by five per cent each year. Boeing also forecasts demand for 24,670 new narrowbodies and 8,590 widebodies.
