Global air travel demand is set to more than double by 2050, according to new long-term projections released by International Air Transport Association, underscoring strong future growth despite a gradual moderation in expansion rates.
The association’s Long-Term Demand Projections (LTDP) indicate that under a mid-range scenario, global passenger demand will reach 20.8 trillion revenue passenger kilometres (RPKs) by 2050. This is based on a compound annual growth rate of 3.1 percent between 2024 and 2050, up from the 9 trillion RPKs recorded in 2024.
In a higher growth scenario, demand could rise to 21.9 trillion RPKs, reflecting a 3.3 percent CAGR, while a lower growth trajectory would still see demand climb to 19.5 trillion RPKs at a 2.9 percent CAGR over the same period. These varying projections are shaped by different assumptions around long-term economic performance, population growth, aviation fuel price trends, the pace of the global energy transition, and the development of air transport capacity.
Commenting on the outlook, Willie Walsh said the demand for air travel remains robust across all modeled scenarios, noting that the anticipated growth will play a significant role in driving global economic and social development. He emphasized that aviation expansion will catalyze job creation and broader opportunities worldwide, while also providing governments, industry stakeholders, and energy suppliers with a solid framework for long-term planning.
He further highlighted the importance of supportive policy frameworks, particularly in areas such as infrastructure development, market access, regulatory harmonization, and the transition to cleaner energy.
The report points to uneven growth across regions, largely reflecting differences in demographics, economic development, market maturity, and connectivity potential. Emerging markets are expected to lead expansion, with Africa and Asia-Pacific projected to record the fastest growth rates at 3.6 percent and 3.8 percent respectively over the 2024 to 2050 period.
In contrast, more mature markets such as Europe and North America are forecast to grow at slower rates of 2.5 percent and 2.8 percent respectively. Among the fastest-growing aviation markets identified are intra-Africa routes, which are projected to grow at 4.9 percent, followed by Africa–Asia-Pacific at 4.5 percent, Asia-Pacific–Middle East and intra-Asia-Pacific both at 3.9 percent, and Africa–North America at 3.8 percent.
These trends reinforce the need for sustained investment in aviation infrastructure and supportive regulatory environments in developing regions, particularly as several Europe-centered markets are expected to record comparatively slower growth.
The LTDP also highlights structural shifts shaping the long-term trajectory of global aviation. It confirms that the COVID-19 pandemic caused a permanent disruption in demand patterns, creating a gap that is not expected to fully return to the pre-pandemic GDP-aligned growth trend by 2050, even under optimistic scenarios.
At the same time, while overall demand remains strong, the pace of growth is gradually slowing. Historical data shows that annual growth averaged 6.1 percent between 1972 and 1998, before declining to 4.5 percent between 1998 and 2024. The projected 3.1 percent CAGR for 2024 to 2050 reflects continued moderation, driven largely by market maturity rather than weakening demand, as total passenger volumes continue to rise significantly.
The projections are based on IATA’s proprietary global econometric model, which integrates data from international institutions alongside the association’s own demand database.
The model draws on more than half a million observations across approximately 41,000 directional country pairs over a 14-year period from 2011 to 2024. It incorporates variables such as population, employment levels, flight frequencies, and aircraft size at the country level, with real GDP per capita, adjusted for purchasing power parity, identified as the most significant driver of demand.
Long-term economic forecasts are sourced from the Organisation for Economic Co-operation and Development, while additional scenarios account for how the global energy transition could influence aviation demand. The model has been validated against historical data and demonstrates an average prediction accuracy of 98 percent at the industry level, providing a high degree of confidence in its long-term outlook.
