Supply Constraints Continue to Reshape Fleet Strategy
By ISTAT Staff
20 July 2026
Aircraft delivery delays and supply chain challenges continue to shape fleet planning across the aviation industry. While manufacturers are working to increase production, airlines, lessors and financiers are adapting their strategies to operate in an environment where constrained supply remains a reality.
Throughout ISTAT Asia, held 12-14 May in Bangkok, Thailand, airline executives, manufacturers, engine specialists and lessors agreed that constrained aircraft and engine availability continues to influence virtually every fleet decision. Rather than waiting for production to return to pre-pandemic expectations, the industry is adapting its strategies around a new reality in which delayed deliveries, extended asset lives and careful fleet planning have become the norm.
Planning Around a Longer Delivery Timeline
Airlines across the region continue to pursue ambitious fleet growth, but those plans increasingly require flexibility.
During the Airline Financing Panel, Captain Wasan Kanjana-huttakit, director and vice president of fleet management at Thai Airways, discussed the carrier’s plan to grow from approximately 40 aircraft following its restructuring to roughly 150 aircraft over the next five years. Alongside that expansion, the airline is evaluating a range of ownership structures and financing options while balancing new deliveries with investments in its existing fleet.
Alvin Limqueco, senior vice president and chief supply chain officer at Philippine Airlines, outlined a similarly ambitious pipeline that includes additional Airbus A350-1000 and A321neo aircraft over the coming years. While acknowledging ongoing manufacturer delays, he emphasized that the airline continues to move forward with long-term fleet investments designed to strengthen both its international and domestic networks.
Mustafa Çavdar, chief financial officer of SunExpress, also highlighted continued fleet expansion, with Boeing 737 MAX deliveries scheduled over the next several years as the airline supports growth across its leisure, visiting friends and relatives (VFR) and domestic markets.
For many airlines, however, delayed deliveries have shifted the conversation from replacing aircraft to maximizing the value of the fleets they already operate.
During his fireside chat, Balagopal Kunduvara, chief financial officer of Garuda Indonesia, explained that the airline expects much of its near-term growth to come through lease extensions and opportunities in the secondary market because new aircraft remain difficult to obtain. At the same time, Garuda is working to simplify fleet deployment and better align aircraft types with specific routes as part of its broader transformation strategy.
Manufacturers Focus on Sustainable Production
Aircraft and engine manufacturers acknowledged the industry’s frustration with ongoing production challenges while emphasizing that restoring output requires long-term stability rather than short-term acceleration.
During the OEM Panel, Kyle Craig, director of product marketing at Pratt & Whitney; Darren Hulst, vice president of commercial marketing at Boeing; Christophe Poulain, vice president of commercial strategy and marketing at Safran; and Alister Read, head of marketing for lessors at Airbus, discussed the industry’s efforts to strengthen supplier networks, improve production visibility and increase manufacturing capacity without compromising quality.
Panelists described demand as fundamentally strong, supported by record backlogs and long-term fleet forecasts across the Asia-Pacific region. Rather than questioning future aircraft demand, the discussion focused on how manufacturers can responsibly increase production while working through supply chain constraints that continue to affect engines, components and other critical systems.
The conversation also looked beyond today’s challenges. Manufacturers highlighted continued investment in next-generation technologies designed to improve fuel efficiency and reduce emissions, underscoring that long-term innovation continues even as the industry works to resolve near-term production issues.
Existing Assets Take on Greater Importance
Limited availability of new aircraft has also elevated the strategic importance of existing fleets.
During the Engine Lessor Panel, Jeff Lewis, CEO of Hanwha Aviation; Jaime Nieto, chief commercial officer of Rolls-Royce & Partners Finance; Rahul Shah, senior vice president of strategic growth and business development for Asia Pacific, Middle East and Africa at AAR; and Roger Welaratne, CEO of SMBC Aero Engine Lease, discussed how constrained engine availability continues to influence maintenance planning, leasing activity and fleet utilization.
Rather than serving simply as replacement equipment, engines have become strategic assets that require careful planning throughout their operating lives. Airlines and lessors alike are extending utilization, optimizing maintenance schedules and seeking creative solutions to maximize availability while waiting for additional production capacity to come online.
Those themes resurfaced during the Global Lessor Leaders Panel, where participants noted that supply constraints continue to support demand for existing aircraft while reinforcing the value of disciplined portfolio management. With delivery delays expected to persist, lessors continue to see strong demand for both new and midlife aircraft capable of meeting airlines’ immediate capacity needs.
