Stuart Fox to Speak at WMES 2026 as IATA Operations Director Amid Industry Challenges
Stuart Fox, Operations Director of the International Air Transport Association (IATA), is scheduled to deliver a keynote address at the World Maintenance and Engineering Symposium (WMES) 2026 in Madrid. His speech comes at a critical juncture as the aviation sector confronts significant operational and financial pressures.
Financial and Operational Strains on the Aviation Industry
IATA has issued a stark warning regarding the outlook for global airline profitability in 2026, projecting net profits to fall to $23 billion—nearly half of the previously forecasted $41 billion. This sharp decline is primarily driven by a $100 billion increase in fuel costs, a consequence of ongoing geopolitical tensions, notably the conflict between the United States and Iran. The fuel price surge exacerbates existing challenges such as delayed aircraft deliveries, engine reliability problems, and acute shortages of spare parts.
The association reports that airlines are contending with unprecedented disruptions in maintenance and supply chains. In 2025 alone, the industry is expected to incur over $11 billion in additional costs. These include $4.2 billion in delayed fuel savings due to the continued operation of older, less fuel-efficient aircraft, $3.1 billion in increased maintenance expenses linked to aging fleets, $2.6 billion in excess engine leasing costs as engines spend extended periods in maintenance, and $1.4 billion in higher inventory costs as airlines stockpile spare parts to mitigate supply chain uncertainties. These financial burdens are diverting resources away from vital investments in network expansion, workforce development, and decarbonization initiatives.
Maintenance Challenges and Fleet Constraints
A recent study conducted by IATA in partnership with Emerton highlights the acute impact on single-aisle engine maintenance. In March 2025, 648 Pratt & Whitney GTF-powered aircraft—representing 28% of the global GTF fleet—were grounded awaiting engine shop visits or spare parts. This situation is expected to worsen as next-generation single-aisle fleets grow. Annual shop visits for CFM LEAP engines are projected to increase dramatically from 600–800 in 2025 to over 5,000 by 2040, while visits for Pratt & Whitney GTF engines are expected to rise from 1,000 to 2,000.
Beyond maintenance, the industry faces a backlog exceeding 18,000 aircraft orders, delivery shortfalls of more than 5,000 units, and an average fleet age now surpassing 15 years. Airlines are compelled to operate less capable fleets than originally planned, striving to improve efficiency, reliability, and environmental performance under these constraints. These challenges are further compounded by production bottlenecks, certification delays, raw material shortages, labor market tightness, and rigid commercial models.
IATA’s Strategic Priorities and Industry Outlook
In response to these multifaceted challenges, IATA has identified four key priorities. First, enhancing supply chain visibility to enable proactive management of disruptions. Second, opening up the aftermarket to increase access to parts and services. Third, leveraging data, digitalization, and artificial intelligence to enable smarter maintenance and operational decisions. Finally, building human capacity to address labor shortages and skill gaps within the industry.
IATA has also expressed concerns regarding passenger safety, urging travelers to prioritize evacuation over recording emergencies during incidents. Additionally, the association noted that growth in European air connectivity stalled in 2025, hindered by regulatory pressures, high costs of sustainable aviation fuel, and operational difficulties.
As Stuart Fox prepares to address WMES 2026, the aviation industry remains focused on navigating these complex headwinds and enhancing resilience for the future.
