European airport trade body ACI EUROPE today released its air traffic report for the month of June, second quarter (Q2) and the first half (H1) of 2025.
Passenger traffic across the European airport network increased by +4.5% in H1 compared with the same period last year, with the pace of growth remaining steady over both Q1 and Q2 — respectively +4.3% and +4.6%.
International passenger traffic accounted for all of the gains (+5.7%) as domestic traffic essentially remained flat (+0.2%). Overall, passenger volumes in H1 stood at +5.1% above their pre-pandemic (H1 2019) levels.
Olivier Jankovec, Director General of ACI EUROPE said: “The positive performance of passenger traffic since the start of the year reflects the continued and strong resilience of demand in the context of significant supply pressures, operational disruptions, increasing geopolitical and geoeconomic tensions and renewed macro-economic uncertainties. All this brings renewed competitive pressures and traffic risks for airports, with much more volatile and unpredictable market dynamics where growth is no longer a given. The Summer season keeps delivering for now — let’s see how the following months will be shaping up… ”
EU+ & REST OF EUROPE
Airports in the EU+ area1 saw passenger volumes increasing by +4.3% in H1 compared to the same period last year, with significant divergences in performance between those located South-East and those located North-West of the bloc.
Accordingly, the best performances came from airports in Slovakia (+19.2%), Poland (+14.9%), Hungary (+14.2%), Malta (+11.7%) and Cyprus (+10.8%) — while airports in Sweden (-0.9%), Estonia (+0.2%), Iceland (+1.4%) and Luxembourg (+1.4%) posted the weakest results.
Amongst the largest EU+ markets, airports in Italy (+5.7%) registered the highest increase in passenger traffic, along with those in Spain (+4.5%). Conversely, airports in France (+3.6%), the UK and Germany (both at +2.3%) underperformed the EU+ average.
Meanwhile, airports in the rest of Europe2 recorded a +5.6% increase in passenger traffic with performance gaps even more significant, reflecting the impact of both geopolitics and contrasted markets dynamics.
This resulted in airports in Moldova (+49.2%), Bosnia & Herzegovina (+31.1%), Israel (+27%), Kosovo (+16.6%) and Georgia (+13.7%) posting impressive results — while those in the larger market of Türkiye (+1.2%) and Azerbaijan (+1.6%) saw modest volume growth.
AIRPORT MARKET SEGMENTS
Major airports (over 40 million passengers) grew at the slowest pace in H1 with their passenger volumes increasing by +3.3% over the same period last year:
- Istanbul Sabiha Gökçen (+11.5%) and Rome Fiumicino (+6.5%) stood out, posting the best performances.
- London Heathrow remained the busiest European airport, welcoming 39.9 million passengers — a modest +0.2% increase over the H1 2024. The British hub was followed by Istanbul (39.1 million passengers | +2.5%), Paris-CDG (34.6 million passengers | +4.3%), Amsterdam Schiphol (32.7 million passengers | +3%) and Madrid (32.6 million passengers | +3%).
Mega airports (25-40 million passengers) saw passenger volumes increasing by +4%, with the best performances coming from Milan Malpensa (+11.4%), Athens and Copenhagen (both at +7.6%).
Large airports (10-25 million passengers) and Medium airports (1-10 million passengers) were the segments achieving the highest growth — both at +5.4%, largely driven by selective Low Cost Carrier expansion and the continued strength of leisure and VFR3 demand:
- Apart from Tel Aviv (+27%) bouncing back, Krakow (+18.7%), Budapest (+15%) and Warsaw (+13.2%) stood out amongst the Large airports.
- Meanwhile, Trieste (+31.8%), Bournemouth (+24.9%), Kaunas (+20.6%), Poznan (+20%), Varna (+19.1%), Genoa (+18%), Girona (+17.1%), Memmingen (+16.4%), Wroclaw (+15.6%), Bari (+15.7%) and Cork (+14.5%) were amongst the fastest growing Medium airports.
Small airports (less than 1 million passengers) also saw a positive momentum with their passenger traffic increasing by +5.1%. However, these airports remain the only ones not having recovered their pre-pandemic (H1) passenger levels (-32.9%).
FREIGHT AND AIRCRAFT MOVEMENTS
Freight traffic across the European airport network remained stable year-on-year in H1 at +0.6% — with EU+ airports at +1% and non-EU+ airports at -2%. When compared to pre-pandemic (H1 2019) volumes, freight volumes stood at +10.4%.
Amongst the top 10 European airports for freight traffic, the best results compared to last year came from Liège (+10.2%), Madrid (+8.9%), and Cologne (+3.5%).
Aircraft movements in H1 increased by +3.1% compared to the same period last year and remained at -2.2% below pre-pandemic (H1 2019) levels.
