Top 10 busiest airports by passenger traffic in 2024-25 list: After several years of disruptions from the COVID-19 pandemic, the aviation industry is experiencing a recovery in passenger numbers, finally surpassing the levels seen in 2019. Global passenger traffic is forecast to reach 9.9 billion in 2025, reflecting a 4.8 per cent year-over-year growth rate.
About 9.5 billion passengers travelled worldwide last year, marking a 3.8% increase compared to pre-pandemic figures in 2019 and a 9% rise from 2023, according to the Airports Council International (ACI) World report.
The United States remains at the forefront of global passenger traffic, with five of the top ten busiest airports located within the country. Hartsfield-Jackson Atlanta International Airport retains its title as the busiest airport in the world by passenger traffic, followed closely by Dubai International Airport in 2024.
Remarkably, China’s Shanghai Pudong International Airport moved from 21st place in 2023 to 10th in 2024, primarily due to its expanded visa policies, the resumption and growth of international flights, operational improvements, and a resurgence in the Asia-Pacific region, particularly in China.
According to the report, the world’s top ten busiest airports account for 9% of global air traffic (approximately 855 million passengers) and experienced an 8.8% increase from 2023 and an 8.4% rise compared to their performance in 2019, when they served 789 million passengers.
