Despite rising geopolitical risks, intense competition and mounting cost pressures across Southeast Asia, its commercial aviation sector is poised for significant growth.  This expansion is expected to be driven by a rising middle class, increased disposable income and strong cross-border tourism and business travel.  To accommodate growing passenger volume, several airport development projects are underway across the region, with Vietnam expected to take the lead, as well as significant projects in Thailand and Cambodia. While passenger traffic has finally rebounded from the lingering effects of the COVID-19 pandemic, the aerospace industry continues to face challenges in aircraft production and supply. This has limited the ability of regional airlines to meet projected fleet increases and retire ageing aircraft. Key constraints include unresolved global supply chain bottlenecks and production backlogs with traditional original equipment manufacturers (OEMs). In light of these challenges, there is an opportunity for alternative OEMs to play a larger role in bridging supply and production gaps.
