European airport trade body ACI EUROPE today released its preliminary air traffic report for September and the third quarter of 2025, showing continued passenger growth across the continent.
Passenger traffic across the European airport network increased +3.6% in September 2025 compared with the same month last year.
Growth in in the non-EU+ area1 (+8.3%) was more than double the continental average and over five percentage points higher than in the more mature EU+ market2 (+2.7%). International passenger traffic (+4.3%) continued to expand faster than domestic demand (+1%).
For the whole third quarter, which covers the peak summer travel months, passenger traffic expanded by +3.9%. This trails the +4.5% and +4.6% registered in Q1 and Q2 respectively.
Olivier Jankovec, Director General of ACI EUROPE commented: “September once again confirmed the overall resilience of passenger traffic, cementing the momentum seen throughout the Summer. This came despite the persistence of a generally low-growth economic environment, but with inflation pressures and unemployment somehow easing a bit. Disparities in traffic performance continue to reflect a combination of factors. These include structural changes in the aviation market, varying levels of market maturity and intensifying airport competition along with punitive taxation and economic divergences across countries – notably in the case of France and Germany.”
