Air Travel Demand Will More Than Double by 2050, IATA Says

IATA Says Air Travel Demand Will More Than Double by 2050

March , 2026 : The International Air Transport Association has projected that air travel demand by 2050 will more than double, according to its latest Long-Term Demand Projections for global passenger travel. The forecast points to continued growth in aviation over the coming decades, although the pace of expansion is expected to vary across regions.

According to IATA, global air passenger demand is projected to reach 20.8 trillion revenue passenger kilometers by 2050 under its mid-range scenario. This is based on a compound annual growth rate of 3.1% between 2024 and 2050, compared with around 9 trillion revenue passenger kilometers recorded in 2024.

IATA also outlined higher and lower growth scenarios. In the higher growth case, passenger demand could reach 21.9 trillion revenue passenger kilometers by 2050, supported by a 3.3% annual growth rate. Under the lower growth scenario, demand would reach 19.5 trillion revenue passenger kilometers, based on annual growth of 2.9%.

The different projections reflect alternative assumptions about long-term economic growth, population trends, aviation fuel prices, the global energy transition, and the ability of the air transport sector to develop supply-side capacity.

IATA Director General Willie Walsh said the outlook for air travel remains positive, with all modeled scenarios showing demand to fly more than doubling by mid-century. He said aviation growth could support economic and social development by creating opportunities, including jobs, while also giving governments, industry, and energy suppliers a basis for long-term planning.

The projection was released by the International Air Transport Association in its Long-Term Demand Projections for air travel.

Growth Expected to Be Strongest in Emerging Markets

IATA said aviation growth will not be evenly spread across the world. Under the mid-range scenario, Asia-Pacific and Africa are expected to be the fastest-growing regions from 2024 to 2050, with projected annual growth rates of 3.8% and 3.6% respectively. Europe and North America are expected to grow more slowly, at 2.5% and 2.8%.

The fastest-growing markets identified in the report include intra-Africa, Africa–Asia-Pacific, Asia-Pacific–Middle East, intra-Asia-Pacific, and Africa–North America. IATA said these growth patterns highlight the need for aviation infrastructure investment and supportive regulatory frameworks in developing regions.

By contrast, several Europe-centered markets are expected to be among the slowest-growing areas in the long-term outlook.

COVID-19 Left a Structural Gap in Aviation Demand

IATA’s report also says the COVID-19 pandemic caused a lasting structural shift in global aviation demand. Unlike previous crises, the sharp collapse in revenue passenger kilometers created a gap that is not expected to fully return to the pre-pandemic, GDP-aligned trend by 2050, even under the high-growth scenario.

At the same time, IATA said long-term demand remains strong, although the rate of growth is gradually moderating. Average annual growth slowed from 6.1% between 1972 and 1998 to 4.5% between 1998 and 2024.

The central forecast for 2024 to 2050 projects a further slowdown to 3.1%.

IATA said this moderation reflects market maturity rather than weaker demand, as total passenger demand is still expected to rise significantly over the long term.

Economic Growth Remains a Key Demand Driver

The IATA model is based on a global econometric framework using international data sources and IATA’s own demand database. The dataset includes more than half a million observations across around 41,000 directional country pairs over 14 years, from 2011 to 2024.

The model includes population, employment, flight frequencies, and aircraft size at the country level. IATA said the most important demand driver is real GDP per capita, adjusted for purchasing power parity. The scenarios are also linked to how the global energy transition may affect long-term aviation demand.

According to IATA, the model has been validated against historical data and shows an average prediction accuracy of 98% at the industry level.

Explainer : What Does IATA’s 85% Share of Global Air Traffic Mean?

The International Air Transport Association says it represents more than 360 airlines, accounting for around 85% of global air traffic. This figure is important, but it needs to be understood correctly. It does not mean IATA controls 85% of the aviation industry. Instead, it means that IATA’s member airlines collectively represent a very large share of the world’s scheduled passenger and cargo traffic.

The remaining 15% is not one separate group, one rival body, or one clearly defined category. It may include airlines that are not IATA members, smaller regional carriers, charter operators, some low-cost airlines, domestic-only airlines, private aviation operators, and other aviation activity that sits outside IATA’s membership coverage.

This matters because IATA’s long-term demand projections carry significant weight. Its membership includes many of the world’s major international passenger and cargo airlines, giving the organization a strong view of global aviation trends, airline demand, and industry planning needs.

However, the remaining 15% also plays an important role in the global aviation system. In developing markets and fast-growing regions, smaller airlines, domestic operators, and non-member carriers can be essential for connecting secondary cities, remote communities, tourism destinations, and regional economies. These operators may not always receive the same global attention as major international airlines, but they are still part of the wider air transport network.

For readers, the 85% figure should therefore be seen as a sign of IATA’s broad industry representation, not as a complete picture of every airline or every flight in the world. IATA’s forecast is highly influential because it reflects the direction of much of the mainstream global airline industry. But aviation growth also depends on airports, governments, regulators, aircraft manufacturers, energy suppliers, regional carriers, and non-IATA operators.

This is why IATA’s projection that air travel demand could more than double by 2050 is more than a passenger traffic forecast. It is also a planning signal for countries and aviation-related industries. If demand grows as expected, governments and businesses will need to prepare for airport capacity, safety regulation, regional connectivity, cleaner energy supply, and infrastructure investment including in areas of aviation that sit outside IATA’s 85% global traffic coverage.
