Over the next three decades, global passenger numbers are expected to reach 17.7 billion by 2043 and 22.3 billion by 2053, according to Airports Council International (ACI) World’s Airport Traffic Forecasts 2024–2053.
The new forecasts, which cover 99.8 per cent of global markets across 161 countries, highlight a compound annual growth rate (CAGR) of 3.4 per cent from 2024 to 2043, with a slightly slower CAGR of 3 per cent from 2024 to 2053. The projections indicate a steady upward trajectory in global aviation, driven by factors such as rising middle-class travel demand in emerging markets, strengthened international travel, and continued investments in airport infrastructure. However, short-term challenges include geopolitical tensions, economic instability, trade shifts like reintroduced tariffs, and supply chain bottlenecks, which may slow recovery in some regions. ACI World Director General Justin Erbacci commented: “Despite the challenges in the near term, global air travel is poised for steady, sustained growth. It is crucial for airports, airlines, and policymakers to take bold, forward-thinking action to anticipate and meet the demands of the future. ACI World remains unwavering in its commitment to support its airport members, helping them navigate evolving dynamics and seize opportunities ahead.” Between 2024 and 2043, global passenger traffic is projected to grow at a CAGR of 3.4 per cent, reaching 17.7 billion passengers. By 2053, global passenger traffic is expected to nearly double, reaching 22.3 billion, reflecting a CAGR of 3 per cent from 2024 to 2053. International passenger traffic is expected to grow at a faster rate than domestic traffic over the next three decades. From 2024 to 2053, international traffic is forecast to grow at a CAGR of 3.3 per cent, while domestic traffic will expand at a slightly slower pace of 2.8 per cent. The number of aircraft movements is expected to increase significantly, reaching 149 million by 2043 and 176 million by 2053. Airports worldwide will need to prepare for this growth by enhancing operational efficiency and investing in infrastructure.
