Brussels: European airport trade body ACI EUROPE today released its preliminary air traffic report for August 2025.

Passenger traffic across the European airport network increased +4.9% in August 2025 compared with August 2024, and ahead of the year‑to‑date average of 4.3%, confirming that summer demand remains strong. 

International passenger traffic led the growth at +5.6%, standing in contrast to domestic traffic gains (+1.6%). Overall, passenger volumes in August stood at +7% above their pre‑pandemic levels (August 2019).

EU+ & REST OF EUROPE

Airports in the EU+ area¹ posted results below the continental average with passenger volumes increasing by +4%. Significant divergences in performance between individual national markets continued in August.

Three countries in the EU+ area registered double‑digit growth year‑on‑year, namely Poland (+15.1%), Slovenia (+11.7%), and Romania (+10.3%). At the other end of the traffic performance spectrum were Latvia (‑6.7%), Estonia (‑4.5%), and Iceland (‑2.5%).

The largest EU+ markets all posted traffic results below the continental average: Germany (+4.2%), Spain (+3.8%), Italy (+2.8%), the UK (+1.7%) and France (+1%).

Meanwhile, airports in the rest of Europe² have grown faster on average than their Western counterparts with an increase of +8.8% year‑on‑year. However, performance gaps in that subgroup are even more significant, reflecting the impact of both geopolitics and contrasted markets dynamics.

This resulted in airports in Moldova (+46.6%), Israel (+38.1%) and Bosnia & Herzegovina (+20.4%) growing well above the group’s average — while those in Russia (‑13.3%), Azerbaijan (+0.7%), Armenia (+7.2%), Uzbekistan (+7.7%) and Serbia (+7.8%) posted results below that line.

AIRPORT MARKET SEGMENTS

Major airports (over 40 million passengers) grew by +3.5% in August 2025 (vs. August 2024):

• Istanbul Sabiha Gökçen (+21.5%) was the fastest growing major airport in Europe, followed by Istanbul Airport (+6.8%).
• Istanbul Airport and Heathrow both surpassed the historic milestone of serving more than 8 million passengers in a single month.

Mega airports (25‑40 million passengers) saw passenger volumes increasing by +4.2%, with the best performances coming from Milan Malpensa (+10.2%), Copenhagen (+8.6%) and Athens (+6.8%).

Strong, above the monthly average growth was posted by Large (10‑25 million passengers), Medium (1‑10 million passengers) and Small (less than 1 million passengers) airport segments, with respectively +6.1%, +5.8%, +6.2%, driven by Low Cost Carrier expansion and the strength of leisure and VFR³ demand, especially during the peak Summer month of August. This resulted in Medium airports growing at double‑digit rate over pre‑pandemic levels. 

• In the Large category, the fastest growing airports all achieved double‑digit growth. Notably, Poland’s strong performance buoyed both Warsaw and Krakow airports to the top 5.
• Amongst Medium airports, Chisinau led the pack with an impressive +46.6% growth.
• Airports topping the Small airports rank recorded triple‑digit growth rates year‑on‑year: Antwerp (+769.4%), Bucharest (+118.6%) and Syros Island (+105.3%).

Small airports, despite achieving a positive momentum, remained the only ones not having recovered their pre‑pandemic passenger levels (‑20.1%).

FREIGHT AND AIRCRAFT MOVEMENTS

Freight traffic across the European airport network decreased by ‑5.8% in August. When compared to pre‑pandemic volumes, freight stood at +7%.

Amongst the top 10 European airports for freight traffic, the best results compared to last year came from Liège (+29%), Madrid (+11.4%), and Milan Malpensa (+6%).
