The Airport Traffic Forecasts 2024–2053 by Airports Council International (ACI) World released last month projects that global passenger numbers are expected to reach 17.7 billion by 2043 and 22.3 billion by 2053, the latter nearly 2.4 times the projected volume for 2024.
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.
These projections indicate a steady upward growth 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 said: “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.”
Global air cargo is also projected to grow steadily, with a CAGR of 2.7 per cent from 2024 to 2043 and 2.4 per cent from 2024 to 2053. However, ACI World cautions that evolving trade policies and supply chain disruptions could introduce volatility in the sector.
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.
