Continuous operational efficiency gains, the rise of low-cost airlines and the growing convenience of flight booking have all contributed to the ongoing commoditization of air travel. Despite China's economic slowdown, the International Air Transport Association (IATA) still expects global passenger volumes to more than double by 2034, reaching 7bn, which will drive demand for incremental aircraft and generate value in the aftermarket. Similarly, while there may be early signs of softening demand, Boeing's long-term market forecast for 2015-34 also foresees the number of aircraft in service doubling. Such growth is expected to see the global MRO market expand from $51bn in 2011 to $71bn by 2021. In this article Russell Pell, Andrew Smith, Delphine Knab and Willem Romanus of Arthur D. Little, discuss delivering long-term value in a transformed aftermarket.
