Athens Airport Among Europe’s Top-Performing Mega Hubs as 2025 Traffic Hits Record Levels
Athens, February 5 – Athens International Airport (AIA) ranked among Europe’s strongest-performing mega hubs in 2025, as passenger traffic across the continent reached a new all-time high. This is according to the Full Year 2025 Airport Traffic Report released by ACI Europe on Thursday.
European airports collectively handled a record 2.6 billion passengers last year, welcoming an additional 100 million travelers compared with 2024. This notable increase occurred despite prevailing economic headwinds, elevated airfares, capacity constraints, and ongoing geopolitical uncertainty.
Athens Airport Ranks Among Europe’s Fastest-Growing Mega Hubs
Athens Airport recorded a significant year-on-year passenger growth of 6.8 percent in 2025. This performance positioned it third among Europe’s mega airports, which are defined as those handling between 25 and 40 million passengers. AIA’s growth was surpassed only by Milan Malpensa and Copenhagen within this category.
This strong showing solidifies Athens’ position among Europe’s fastest-growing large hubs. The airport has benefited from sustained international travel demand and a more robust growth trajectory compared to many established aviation markets across the continent.
Greece Outperforms European Average in 2025
At a national level, Greece also delivered a solid performance in 2025. Overall passenger traffic across the country rose by 5.1 percent year-on-year, according to ACI EUROPE data. This figure notably outperformed the European average growth rate of 4.4 percent.
Greece’s growth exceeded that of several of Europe’s largest aviation markets, including Germany, France, and the United Kingdom, and slightly outpaced Italy. This reflects the continued strength in international demand and leisure-driven travel flows within the country. This positive national backdrop largely explains the strong results observed at Athens Airport, as well as the positive momentum evident across various parts of Greece’s regional airport network.
Syros Island Stands Out Among Europe’s Small Airports
Beyond major hubs, Greece also made its mark in the small airports category. Syros Island Airport ranked fourth among Europe’s fastest-growing small airports, recording an impressive passenger growth of 51.1 percent year-on-year.
ACI EUROPE noted that while small airports posted some of the strongest growth rates in 2025, this segment remains the only one yet to fully recover to pre-pandemic traffic levels.
European Passenger Traffic Sets New Record in 2025
European airport traffic returned to a “normalized” growth pattern in 2025, primarily driven by international passengers. Freight and aircraft movements also recorded moderate increases, according to ACI EUROPE.
Across the entire European airport network, passenger traffic increased by 4.4 percent year-on-year in 2025, marking a return to more typical growth patterns following the post-pandemic rebound. This growth was driven entirely by international traffic, which saw a 5.6 percent rise, while domestic passenger volumes remained largely flat.
Traffic momentum strengthened toward the end of the year, with fourth-quarter growth accelerating to 6.1 percent, providing a positive signal heading into 2026.
“If anything, last year’s traffic performance is yet another proof that air connectivity is a powerful and largely resilient economic driver,” stated ACI EUROPE Director General Olivier Jankovec, emphasizing the close link between aviation and tourism demand across Europe.
Outlook for 2026: Growth Continues but Capacity Pressures Loom
Looking ahead, ACI EUROPE anticipates passenger traffic growth to continue in 2026, though at a more moderate pace of approximately 3.3 percent. This sustained growth is expected to be supported by improving economic prospects and continued consumer appetite for travel.
“Aviation is a critical enabler of competitiveness,” Jankovec remarked, while cautioning that infrastructure capacity constraints – both on the ground and in the air – will remain a key challenge. He also raised concerns over the full rollout of the Schengen Entry/Exit System, underscoring the vital role of policy decisions in shaping the sector’s resilience in the year ahead.
