Airports Council International (ACI) World has released an exclusive early look at the 2024 global airport rankings, showcasing significant gains in passenger traffic and a strong return to pre-pandemic performance levels.
According to ACI preliminary data indicates that global passenger traffic in 2024 is nearing 9.5 billion, reflecting a 9% increase over 2023 and a 3.8% rise compared to 2019, the last full year before the COVID-19 pandemic.
The Top 10 busiest airports collectively handled approximately 855 million passengers, accounting for 9% of total global traffic. This represents an 8.8% increase over 2023 and an 8.4% gain compared to 2019, when these same airports processed 789 million passengers.
Hartsfield-Jackson Atlanta International Airport continues to lead the global rankings as the world’s busiest airport, followed by Dubai International Airport and Dallas Fort Worth International Airport.
One of the most notable shifts in the rankings came from Shanghai Pudong International Airport, which made a dramatic leap from 21st place in 2023 to 10th in 2024. This rise was driven by expanded visa policies, the resumption and growth of international flight operations, and improved airport efficiencies.
These results highlight not only the recovery of global air travel but also the evolving dynamics of international passenger traffic, with Asia making a strong comeback on the global aviation stage.
The unwavering strength of Istanbul Airport and New Delhi International Airport keep them in top ranks, marking significant progress over 2019. Both airports have been thriving due to airline expansion, infrastructure growth, and enhanced global connectivity.
Navigating global uncertainty
2024 saw global passenger growth face significant uncertainties that stemmed from evolving economic and geopolitical landscapes. Ongoing supply chain challenges and production delays from aircraft manufacturers, as well as geopolitical tensions, posed a risk to growth opportunities by potentially altering flight routes, increasing operational costs, and affecting passenger sentiment. Additionally, the threat of tariffs raised concerns about potential disruptions to global trade, which indirectly affected international travel demand and increased constructions.
In 2025, global passenger traffic is forecast to reach 9.9 billion with a 4.8% year-over-year growth rate. While passenger demand remains strong, the pace of expansion is expected to slow as markets shift from recovery-driven surges to structural, long-term growth patterns.
Key challenges such as economic uncertainty, geopolitical tensions, and capacity constraints are expected to increasingly shape the industry’s trajectory. In advanced markets, demand stabilization, supply chain bottlenecks in aircraft production and airport capacity shortage may temper growth, while in emerging markets, higher infrastructure investment and rising middle-class travel demand will likely continue to drive expansion. As the industry moves into a new era of growth, the airport industry must focus on financial viability, investment in infrastructure, operational efficiency, and sustainability.
