London, September 3 - Australia's Macquarie AirFinance, the global aircraft leasing arm of Macquarie Group, has announced a significant expansion of its fleet with the purchase of 30 Boeing 737-8 aircraft, marking its second direct order with Boeing. This strategic acquisition, booked in July 2025 as an unidentified order on Boeing’s Orders & Deliveries website, increases Macquarie AirFinance’s total 737 MAX order book to 70 aircraft, with deliveries scheduled through 2032. The move aligns with the company’s goal to transition to more fuel-efficient, next-generation aircraft to meet the growing demand from its airline customers for modern, sustainable, and cost-effective fleet solutions. The Boeing 737-8, part of the 737 MAX family, is designed to reduce fuel consumption and carbon emissions by approximately 20% compared to the older models it replaces, making it an attractive option for airlines aiming to enhance operational efficiency while addressing environmental sustainability goals. This order underscores Macquarie AirFinance’s commitment to supporting its global network of airline partners as they navigate competitive market conditions and rising passenger traffic.

The Boeing 737-8 is a versatile, single-aisle jet capable of carrying up to 210 passengers and operating on routes extending to 3,500 nautical miles (6,480 km). Powered by CFM Leap-1B engines, the aircraft offers exceptional fuel efficiency, reliability, and passenger comfort, making it an ideal choice for airlines seeking to modernize their fleets. Macquarie AirFinance’s decision to expand its 737 MAX portfolio reflects the aircraft’s strong market demand, with the 737 family representing approximately 30% of all financed airplanes globally. The lessor’s current portfolio includes 227 aircraft leased to 84 airlines across 48 countries, and this latest order complements its existing firm order book of 105 new-technology narrowbody aircraft from both Boeing and Airbus. By investing in the 737-8, Macquarie AirFinance is positioning itself to meet the needs of its airline customers, who are increasingly prioritizing fuel-efficient aircraft to reduce operating costs and environmental impact in response to global aviation trends.
This order is part of a broader industry shift toward fleet modernization, driven by the need to replace aging aircraft and meet rising air traffic demands. Boeing’s 2025 Commercial Market Outlook forecasts a need for 33,000 new single-aisle aircraft over the next two decades to support fleet renewals and growth in global air travel. Macquarie AirFinance’s strategic expansion strengthens its role as a leading provider of aircraft leasing and financing solutions, enabling its airline partners to access state-of-the-art aircraft that enhance operational efficiency. The 737 MAX’s proven reliability and lower operating costs make it a cornerstone of many lessors’ portfolios, with lessor orders accounting for nearly 25% of the 737 MAX order book. This acquisition not only bolsters Macquarie AirFinance’s competitive position in the leasing market but also supports Boeing’s efforts to secure large-scale orders, as evidenced by other significant deals in 2025, such as Korean Air’s $36.5 billion order for a mix of Boeing aircraft.
The partnership between Macquarie AirFinance and Boeing highlights the critical role of lessors in the aviation ecosystem, providing financial solutions that facilitate fleet expansion and modernization for airlines worldwide. Eamonn Bane, CEO of Macquarie AirFinance, emphasized that this order marks a milestone in the company’s growth strategy, reinforcing its commitment to delivering sustainable and cost-effective solutions. Boeing’s senior vice president of Commercial Sales and Marketing, Brad McMullen, noted that the 737 MAX’s value to the leasing community and airlines underscores its importance in driving fleet renewals. As Macquarie AirFinance continues to grow its 737 MAX portfolio, it is well-positioned to capitalize on the increasing demand for fuel-efficient aircraft, supporting the global aviation industry’s transition toward a more sustainable future while meeting the operational needs of its airline partners across its extensive global network.
