Boeing projects a demand for 36,770 new airplanes over the next 20 years, an increase of 4.2% from last year’s forecast. The company released its annual Current Market Outlook (CMO) on July 10th in London, estimating the total value of those new airplanes at $5.2 trillion. Fueling this year’s forecast is the single-aisle market, which is projected to be the fastest growing and most dynamic segment due to the continued emergence of low-cost carriers. 25,680 new airplanes will be needed in this segment, making up 70% of the total units in the forecast. Boeing forecasts that 8,600 new airplanes will be needed in the twin-aisle segment, led by small widebody airplanes in the 200 to 300 seat range such as the 787-8 and 787-9 Dreamliner. This year’s forecast reflects a continued shift in demand from very large airplanes to efficient new twin-engine products such as the 787-10 and new 777X.
