At the Farnborough Airshow 2026, Aerolíneas Argentinas confirmed a leasing agreement with Aviation Capital Group (ACG) for six Boeing 737 MAX 10 aircraft. The first delivery is expected in 2028, contingent on the FAA certification of the MAX 10, which is reportedly nearing completion. This deal marks a significant step for the Argentine carrier as it modernizes its fleet and expands capacity on high-demand domestic and regional routes. The MAX 10, the largest variant of the 737 MAX family, is designed for high-density short- and medium-haul operations. Aerolíneas Argentinas plans to deploy these aircraft from its two Buenos Aires hubs: Aeroparque Jorge Newbery for domestic and regional flights, and Ezeiza for international services. CEO Fabián Lombardo stated that the MAX 10s are a "key element" of the 2027-2031 fleet plan, adding seats on busy routes, improving operational efficiency, and enhancing passenger competitiveness. The airline aims to build a "more modern, efficient, and sustainable" fleet. This leasing arrangement aligns with a broader renewal strategy. In December 2025, Aerolíneas Argentinas outlined a self-funded plan to incorporate new Boeing 737 MAX and Airbus A330neo aircraft, reducing reliance on state subsidies. Currently, the airline operates a mixed fleet of Airbus A330-200s (10), Boeing 737-700s (4), 737-800s (28), 737 MAX 8s (15), and Embraer 190s (24). The addition of MAX 10s will increase seat capacity and lower per-seat costs on dense routes, a critical factor for profitability in the competitive Latin American market. For ATPL and ATC students, this news illustrates real-world fleet planning and the role of leasing in airline strategy. Leasing allows carriers to secure modern aircraft without large capital outlays, spreading costs over time. The pending MAX 10 certification also highlights regulatory hurdles that impact airline operations and scheduling. Understanding these dynamics is essential for future pilots and controllers who will work with such aircraft and manage the associated operational changes. ACG's involvement underscores the lessor's confidence in the MAX 10. In January 2026, ACG ordered an additional 50 737 MAXs, including 25 MAX 10s, bringing its total 737 MAX backlog to 121 aircraft. ACG holds the largest MAX 10 order book among lessors, attracted by the model's fuel efficiency and capacity. This deal ensures a steady delivery stream from 2026 to 2033, benefiting airlines like Aerolíneas Argentinas that seek flexible fleet expansion.
