IATA Says Air Travel Demand to More Than Double by 2050

The International Air Transport Association (IATA) projects that global air passenger demand is expected to more than double by 2050.

“The outlook for air travel is positive. People want to travel and, under all our modelled scenarios, the demand to fly is expected to more than double by mid-century,” said Willie Walsh, IATA’s Director General.

“That is good news for global economic and social development because aviation growth will catalyze opportunities, including jobs, around the world. Our Long-Term Demand report gives governments, industry, and energy suppliers a robust basis for long term planning,” Walsh added. 

Under the mid-range scenario, demand is forecast to reach 20.8 trillion revenue passenger kilometers (RPKs), based on a compound annual growth rate (CAGR) of 3.1% (2024-2050) from the 9 trillion RPKs seen in 2024. 

A higher growth scenario would see a 3.3% CAGR with passenger demand reaching 21.9 trillion RPKs in 2050. A lower growth scenario would see 2.9% CAGR with passenger demand reaching 19.5 trillion RPKs by 2050.

The different scenarios are driven by alternative modeling of long-term economic growth, populations, aviation fuel price trends, the global energy transition, and air transport supply-side capacity development. 

Regional Outlook: Growth Concentrated in Emerging Markets

The pace of growth will be uneven across regions, reflecting differences in demographics, market maturity, economic development, and connectivity potential. Under the mid-range scenario, Asia Pacific and Africa are expected to be the fastest growing regions over 2024-2050, with CAGRs of 3.8% and 3.6% respectively. Europe and North America are projected to grow more slowly, at 2.5% and 2.8%. 

Long Term Global Trends

Two long-term trends identified in the report are worth noting:

The long-term demand projection confirms that the COVID 19 pandemic caused a permanent structural shift in global aviation demand. Unlike previous crises, the unprecedented collapse in RPK has created a persistent gap that is not expected to converge back to the pre-pandemic GDP-aligned trend by 2050, even under the high growth scenario. 

While long term demand remains robust, the growth rate is moderating gradually. Historical analysis shows that average annual growth slowed from 6.1% CAGR between 1972 and 1998, to 4.5% CAGR between 1998 and 2024. The central scenario for 2024-2050 projects a further slowing to 3.1% CAGR. This gradual moderation reflects market maturity rather than weakening demand, as absolute passenger numbers continue to rise significantly.
