Aviation leaders gathering in Singapore on Monday warned that persistent supply chain disruptions and rising geopolitical tensions are increasingly threatening the industry’s ability to meet surging demand, even as they reaffirmed commitments to cut carbon emissions. The discussions took place on the eve of the Singapore Airshow, Asia’s largest aviation event, against a backdrop of slowing deliveries, strained logistics, and growing political interference in global trade systems.
Addressing industry executives and regulators at the Changi Aviation Summit, International Air Transport Association Director General Willie Walsh said supply chain problems were continuing to weigh heavily on global airlines and were unlikely to ease quickly. He noted that disruptions that began during the COVID-19 pandemic have had a lasting impact on aircraft production and maintenance, affecting airlines’ capacity planning and fleet expansion.
Aircraft manufacturers Airbus and Boeing have struggled with shortages and bottlenecks across their supplier networks, while engine makers such as GE Aerospace and Pratt & Whitney are facing mounting pressure as they try to balance demand from new aircraft assembly lines with the need to service and repair engines already in operation. These constraints have slowed deliveries and kept aircraft grounded for longer than expected, adding costs for airlines worldwide.
The industry is also grappling with shifting geopolitical dynamics, including U.S. import tariffs that have disrupted established air freight flows. Walsh said the effects of geopolitical change have been felt more sharply in air cargo than in passenger travel. He noted that air cargo shipments between Asia and North America fell by 0.8% last year, marking the first decline in some time, while cargo volumes between Europe and Asia rose by 10.3%, highlighting how trade patterns are being reshaped.
Despite these challenges, Asia-Pacific remains the fastest-growing aviation market globally, driven largely by China and India. Passenger traffic in the region is projected to grow by 7.3% in 2026, underscoring the scale of demand the industry must accommodate. However, Toshiyuki Onuma, the newly elected president of the governing council of the International Civil Aviation Organization, warned that existing systems are ill-equipped to handle such growth without major reforms.
Onuma said a global aviation system designed for around 4 billion passengers a year cannot simply scale up to support three times that number without fundamental transformation. He stressed that alongside capacity expansion, the industry must accelerate progress toward its goal of achieving net-zero carbon emissions by 2050, calling for coordinated international action to ensure safe, sustainable growth.
Concerns over the “weaponisation” of supply chains loomed large over the conference, attended by around 350 aviation leaders. Tensions surrounding aircraft certification standards have raised fears of disruption to a long-standing system of globally accepted norms that underpin aviation safety and trade. While Onuma did not directly reference recent remarks by U.S. President Donald Trump demanding that Canada certify certain U.S.-designed Gulfstream business jets or face tariffs, he emphasised the importance of cooperation and independence in regulatory processes.
Industry officials expressed alarm that certification decisions could become subject to political pressure. A senior regulatory official said there could be no bargaining over aircraft certification, warning that any erosion of trust in the system would have serious implications for safety and international commerce.
European Union Transport Commissioner Apostolos Tzitzikostas echoed these concerns, warning that major powers are increasingly using supply chain dependencies as geopolitical tools. He said such weaponisation poses real risks to the future growth of aviation, particularly as globalisation-driven cross-border supply chains come under strain. His remarks reinforced earlier warnings from France’s aerospace industry that the retreat from globalisation could undermine the integrated supply networks on which aviation has long depended.
