Global passenger traffic nears 9.8 billion
Global air travel continued its recovery in 2025, with total passenger numbers estimated at 9.8 billion, according to preliminary data released by Airports Council International (ACI). That marks a 3.6% increase over 2024 and a 7.3% rise compared with 2019, the last full year before the pandemic.
ACI, which represents more than 2,200 airports across 181 countries, will finalize its traffic figures in July. While overall growth remained solid, industry leaders caution that 2026 brings heightened uncertainty due to geopolitical tensions and economic pressures.
Atlanta holds top spot despite slight dip
Hartsfield-Jackson Atlanta International Airport (ATL) retained its title as the world’s busiest airport in 2025, handling 106.3 million passengers. The figure represents a 1.6% decline from 2024 and nearly a 4% drop from 2019, yet it was still enough to secure the top ranking.
The Atlanta hub has claimed the No. 1 position for 27 of the past 28 years, briefly losing it in 2020 when pandemic-related restrictions sharply curtailed air travel.
Dubai International Airport (DXB) maintained second place with 95.2 million passengers, up 3.1%. Tokyo Haneda (HND) climbed to third, handling 91.7 million passengers, a 6.7% increase. Dallas Fort Worth (DFW) ranked fourth with 85.7 million passengers, while Shanghai Pudong (PVG) rounded out the top five at 85 million, posting one of the strongest growth rates at 10.7%.
2026 outlook clouded by geopolitics
Despite strong numbers in 2025, the aviation sector faces potential headwinds in 2026. Dubai, which also ranks No. 1 globally for international passengers, has experienced operational disruptions amid the ongoing conflict in the Middle East.
Fuel prices have risen, pushing ticket fares higher worldwide. Airlines have adjusted routes to avoid affected regions, and industry leaders warn that prolonged instability could disrupt fuel supply chains.
ACI Director General Justin Erbacci noted that if geopolitical tensions persist, airlines may face constraints on fuel availability, influencing route decisions and potentially affecting global travel demand. Broader economic pressures and inflation could also shape travelers’ choices.
For now, demand remains resilient. ACI expects the strongest future growth in Africa, the Middle East and Asia-Pacific, with steadier expansion in North America and Europe.
