The International Air Transport Association (IATA) released its Long Term Demand Projections for air travel, presenting a range of scenarios that all point to a substantial rise in global passenger demand by 2050.
Under IATA's central or mid-range case, passenger traffic measured in revenue passenger kilometers (RPKs) is projected to climb from 9 trillion in 2024 to 20.8 trillion in 2050. That implies a compound annual growth rate (CAGR) of 3.1% across the 2024-2050 period. IATA's higher-growth projection would lift demand to 21.9 trillion RPKs by 2050, a 3.3% CAGR, while a lower-growth path would see 19.5 trillion RPKs and a 2.9% CAGR.
IATA attributes the spread of these scenarios to differing assumptions about long-term economic expansion, demographic trends, aviation fuel prices, the trajectory of the global energy transition, and developments on the supply side of air transport capacity. Those variables form the basis of alternative models that produce the high, mid and low forecasts.
Willie Walsh, IATA's Director General, described the outlook as positive and emphasized that demand to fly remains strong. He noted that in every scenario modeled by the association, demand is expected to more than double by mid-century. Walsh framed that outcome as beneficial for global economic and social development, saying aviation growth will spur opportunities, including job creation, in multiple regions.
The pace of expansion is not projected to be uniform. IATA's mid-range scenario identifies Asia Pacific and Africa as the fastest-growing regions between 2024 and 2050, with CAGRs of 3.8% and 3.6%, respectively. By contrast, Europe and North America are forecast to expand more slowly, at 2.5% and 2.8% CAGRs.
Route-level projections in the report highlight several of the strongest segments: intra-Africa travel is forecast to grow at 4.9% CAGR, travel from Africa to Asia Pacific at 4.5%, Asia Pacific to Middle East at 3.9%, intra-Asia Pacific at 3.9%, and Africa to North America at 3.8%.
The projections also spell out a lasting effect from the COVID-19 pandemic. IATA finds that the collapse in RPKs during the pandemic created a structural gap that is not expected to revert to the pre-pandemic GDP-aligned trend by 2050, even under the higher-growth scenario. In other words, the industry is not anticipated to fully recapture the earlier trajectory it was on prior to the pandemic.
Long-term growth, while solid, is projected to moderate relative to historical averages. IATA's historical analysis shows a step-down in long-run annual growth: a 6.1% CAGR for the period 1972-1998, followed by a 4.5% CAGR from 1998-2024. The association's central forecast for 2024-2050 expects a further slowdown to a 3.1% CAGR.
Taken together, the figures in IATA's Long Term Demand Projections sketch a sector that is poised to expand substantially in absolute terms over the next quarter-century, but at a gradually decelerating rate compared with past decades. Growth will concentrate in certain regions and routes, and the pandemic-era structural shift in demand patterns will leave a persistent imprint on the industry through 2050.
Summary
IATA projects global air passenger demand will more than double by 2050 under all modeled scenarios. The mid-range case forecasts 20.8 trillion RPKs by 2050 (3.1% CAGR), rising from 9 trillion RPKs in 2024. Growth will be fastest in Asia Pacific and Africa, while the pandemic has produced a lasting gap from the pre-COVID trend.
Key points
- Mid-range projection: 20.8 trillion RPKs by 2050, 3.1% CAGR from 2024.
- Alternative scenarios: high case 21.9 trillion RPKs (3.3% CAGR), low case 19.5 trillion RPKs (2.9% CAGR).
- Regional dynamics: Asia Pacific (3.8% CAGR) and Africa (3.6% CAGR) lead growth; Europe (2.5%) and North America (2.8%) lag.
Sectors impacted - Airlines, aircraft manufacturers, airports, tourism and employment in regions with rising connectivity; energy markets linked to aviation fuel and the broader energy transition.
Risks and uncertainties
- The persistence of the structural gap caused by the COVID-19 pandemic, which the report finds will not realign with the pre-pandemic GDP-aligned trend by 2050.
- Variability in key drivers such as long-term economic growth, demographics, aviation fuel price trends, the pace of the energy transition, and supply-side capacity developments, which are the basis for the divergent scenarios.
- Uneven regional growth reflecting differences in market maturity, demographics and connectivity potential, leading to concentration of traffic growth in certain corridors and regions.
