The world is ready to fly again - and far more than before. A new long-term outlook from the International Air Transport Association (IATA) shows that by mid-century, demand for air travel will not just recover, but more than double, DKNews.kz reports.
This is not just a set of numbers - it is a clear signal of how the global landscape will evolve over the coming decades.
Travel will become routine for billions
Under IATA’s base-case scenario, passenger traffic, measured in revenue passenger kilometers (RPK), will grow from 9 trillion in 2024 to 20.8 trillion by 2050. That translates into an average annual growth rate of 3.1%.
In a more optimistic scenario, traffic could reach 21.9 trillion RPK. Even under a conservative outlook, the market is expected to nearly double to 19.5 trillion.
In simple terms, more people will fly, more often, and over longer distances than ever before.
Why aviation will keep growing
The main reason is straightforward - people want to travel. But several underlying drivers are shaping this trend:
- global economic growth
- population expansion
- new route development
- improved affordability
- expansion of airline fleets
IATA
IATA Director General Willie Walsh said:
“The outlook for air travel is positive. People want to travel, and across all our scenarios, demand is expected to more than double by the middle of the century. This is good news for the global economy and for society, as aviation creates opportunities worldwide, including new jobs. Our long-term forecast provides governments, industry and energy providers with a clear basis for planning ahead. At the same time, it highlights that sustainable growth depends on the right conditions: efficient infrastructure, market access, aligned regulation and progress in the transition to cleaner energy sources.”
Where growth will be strongest
Growth will not be evenly distributed.
Emerging markets will lead the way:
- Asia-Pacific - around 3.8% annually
- Africa - around 3.6%
Meanwhile, mature markets will grow more moderately:
- Europe - around 2.5%
- North America - around 2.8%
The fastest-growing markets include:
- intra-Africa routes
- Africa - Asia-Pacific
- Asia-Pacific - Middle East
- intra-Asia-Pacific
- Africa - North America
This points to a gradual shift in the center of gravity of global aviation.

The pandemic changed the trajectory
IATA highlights a key structural shift: COVID-19 has left a lasting impact.
Even by 2050, demand is not expected to fully return to the pre-pandemic growth trajectory. The gap will remain.
In other words, aviation will continue to grow - but along a new path.
Growth is slowing - and that’s normal
Another important trend is the gradual slowdown in growth rates.
Historically, aviation expanded rapidly:
- 1972–1998 - 6.1% annually
- 1998–2024 - 4.5%
Looking ahead, growth is expected to average around 3.1% between 2024 and 2050.
This is not a negative sign.
It reflects market maturity. Passenger numbers will continue to rise, but growth will become more stable and predictable.
How the forecast was built
IATA’s projection is based on one of the most robust models in the industry.
It draws on more than 500,000 data points across approximately 41,000 routes from 2011 to 2024.
The model takes into account:
- population
- employment levels
- flight frequency
- aircraft capacity
- income levels
The key driver is real GDP per capita, adjusted for purchasing power parity.
The model has been validated against historical data and delivers an accuracy of around 98%, making it one of the most reliable forecasting tools in aviation.

The bottom line
The future of aviation is not just about more aircraft.
It is about a more connected world.
More people will travel, access new opportunities and build stronger global links.
But with growth comes responsibility - for infrastructure, sustainability and accessibility.
And the shape of the skies in 2050 will depend on how these challenges are addressed today.
