Global Air Demand to Double by 2050, IATA Says

Global air passenger demand is expected to more than double by 2050, reaching 20.8 trillion revenue passenger kilometers (RPKs) under a mid-range scenario, according to the International Air Transport Association (IATA). The projection implies a compound annual growth rate (CAGR) of 3.1% between 2024 and 2050, up from 9 trillion RPKs recorded in 2024, and provides a long-term planning framework for airlines, governments and infrastructure providers.

Alternative scenarios suggest demand could reach 21.9 trillion RPKs under a higher-growth case (3.3% CAGR), or 19.5 trillion RPKs under a lower-growth scenario (2.9%). These variations are based on assumptions related to economic growth, demographic trends, aviation fuel prices and supply-side capacity. 

“The outlook for air travel is positive. People want to travel and, under all our modeled scenarios, demand is expected to more than double by mid-century,” said Willie Walsh IATA's general director. He added that aviation growth will support economic activity and job creation, while emphasizing the need for policy frameworks that enable infrastructure development and regulatory alignment.

Regional Growth Patterns and Structural Shifts

Growth is expected to vary significantly across regions, with emerging markets leading expansion. Asia-Pacific and Africa are projected to record the fastest growth between 2024 and 2050, with CAGRs of 3.8% and 3.6%, respectively. In contrast, Europe and North America are expected to grow more slowly, at 2.5% and 2.8%, reflecting differences in market maturity, demographics and economic development.

The fastest-growing aviation markets include intra-Africa routes (4.9%), Africa–Asia-Pacific (4.5%) and Asia-Pacific–Middle East (3.9%). These corridors are likely to concentrate demand and require targeted investment in airport infrastructure and connectivity. By comparison, several Europe-centered markets are projected to expand at a more moderate pace due to more mature demand conditions.

Long-term projections also point to structural shifts following the COVID-19 pandemic. According to IATA, the collapse in RPKs during the crisis created a lasting gap that is unlikely to fully converge with pre-pandemic GDP-aligned trends by 2050. At the same time, growth rates are moderating, with historical expansion declining from 6.1% CAGR between 1972 and 1998 to a projected 3.1% through 2050, reflecting increasing market maturity.

Sustainability Pressures and Supply Constraints

Sustainability remains a central challenge for the aviation sector heading into 2026 and beyond. The World Economic Forum  has described the current approach as “ambitious pragmatism,” reflecting incremental progress in technology and policy. Survey data indicate that nearly half of aviation executives expect meaningful progress in decarbonization in 2026, although confidence has declined slightly compared to the previous year. Around one-third of respondents expressed pessimism, citing high costs and limited availability of sustainable aviation fuels. Despite these challenges, industry targets remain unchanged, reinforcing a commitment to net-zero emissions by 2050.

Electro-sustainable aviation fuel (e-SAF) could supply more than 40% of SAF demand by 2050, according to IATA, but scaling remains uncertain. With no commercial plants currently in operation and high production costs, supply constraints and infrastructure gaps are likely to limit availability before 2030.

Manufacturing bottlenecks continue to constrain fleet renewal and operational efficiency. Airbus delivered close to 800 aircraft in 2025, while Boeing delivered around 600 and led in orders with 1,175. Both manufacturers, however, reported ongoing supply chain disruptions, workforce shortages and production constraints affecting output and delivery timelines.

Engine shortages have emerged as a critical bottleneck, causing delays, aircraft groundings and operational inefficiencies. Limited availability of engines and spare parts has forced airlines to extend the use of older aircraft, increasing fuel consumption and emissions. Supply chain disruptions affecting key components, including avionics and fuselage sections, have further widened the gap between demand and production capacity.

These constraints have direct implications for sustainability efforts. Delays in deploying new-generation aircraft slow emissions reductions and increase operating costs. While long-term innovation initiatives, including advanced propulsion technologies and projects led by Boom Supersonic, continue to advance, they are unlikely to resolve near-term production challenges or ease pressure on sustainable fuel supply.

The broader outlook from the International Civil Aviation Organization points to both recovery and expansion. Global passenger traffic is expected to reach 4.6 billion in 2024 and grow to 12.4 billion by 2050, while air cargo is projected to increase from 265 billion to 638 billion freight tonne kilometers.
