Global air travel demand is forecast to more than double by 2050 with Asia Pacific and Africa leading growth, placing urgent focus on aviation infrastructure, capacity and sustainability across these key markets.
Global air travel demand is set to surge over the next 25 years, with the International Air Transport Association (IATA) forecasting passenger volumes will more than double by 2050.
The outlook is driven by long-term economic expansion, population growth and increasing connectivity, particularly across emerging markets.
IATA’s projections also factor in aviation fuel price trends, the transition to cleaner energy and improvements in infrastructure and airline capacity.
Growth in air travel demand will vary significantly by region, with emerging markets leading the charge.
Asia Pacific, Africa and the Middle East are expected to see the fastest expansion between 2024 and 2050, while Europe and North America are forecast to grow at a slower pace due to having more mature markets.
The fastest-growing routes are expected to connect developing regions, including intra-Africa (4.9%), Africa–Asia Pacific (4.5%), Asia Pacific–Middle East (3.9%), intra-Asia Pacific (3.9%) and Africa–North America (3.8%).
The air travel demand forecast highlights a significant challenge for global aviation: keeping pace with future passenger volumes.
In 2024, global air travel reached approximately nine trillion revenue passenger kilometres (RPKs), a key industry metric measuring passenger traffic and distance flown.
Under IATA’s mid-range scenario, this is expected to more than double to 20.8 trillion RPKs by 2050. In a high-growth scenario, demand could reach 21.9 trillion RPKs even sooner, underscoring the urgency for capacity planning.
To accommodate this growth, the industry will require substantial investment in airport infrastructure, air traffic management systems and supportive regulatory frameworks.
The IATA report notes that the COVID-19 pandemic created a lasting structural shift in global air travel demand.
While the industry has recovered strongly, there is a persistent gap in RPKs compared to pre-pandemic growth trajectories that is not expected to return to pre-2019 trends.
This shift reinforces the importance of realistic, flexible planning for future demand rather than relying solely on historic trends.
IATA Director General Willie Walsh said the long-term outlook for aviation remains strong, but enabling that growth will depend on coordinated global action.
“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,” he said.
“That is good news for global economic and social development because aviation growth will catalyse opportunities, including jobs, around the world.
“Our Long-Term Demand report…underscores the need for policy frameworks to support key success enablers, such as efficient infrastructure development, market access facilitation, regulatory harmonisation and an effective clean energy transition.”
KARRYON UNPACKS: The air travel demand forecast presents both opportunity and pressure. Advisors and industry players need to keep an eye on capacity, pricing and infrastructure investment as aviation scales to meet future global demand.
