The upward trend in Greek tourism is clearly reflected in the figures for international air arrivals for 2025, with the country approaching 31 million passengers and further strengthening its position as a leading Mediterranean destination. According to INSETE’ s analysis, international arrivals totaled 31,041,051 passengers, compared to 29,316,137 in 2024, marking an increase of 1,724,914 passengers, or 5.9%.
This increase is not limited to absolute numbers, but also reflects a more complex change in the structure of tourism demand, with indications of geographical differentiation, the strengthening of new markets, and a gradual decongestion of the intense seasonality that has historically characterized Greek tourism.
At the level of the main markets, the United Kingdom maintains its dominant position with 5,433,127 arrivals, an increase of 3.5%, confirming the stable relationship of the British market with Greece. Germany follows with 5,077,784 passengers, recording the largest increase in absolute numbers (+278,679), while Italy remains in third place with 2,561,596 arrivals. France and Poland complete the top five with 1,759,888 and 1,527,659 passengers respectively, with these five countries accounting for a total of 53% of international arrivals.
Beyond traditional European markets, significant increases from markets such as Israel (+27.2%), the United States (+18.5%), and Turkey (+14.5%) are of particular importance, indicating the strengthening of Greece’s connection to high-spending markets with different travel profiles. At the same time, there are some selective retreats, such as in the case of the Netherlands and Belgium, an element that shows a redistribution of demand within the European market.
Seasonality changes its face
The analysis of the monthly distribution of arrivals reveals a critical structural characteristic: the gradual expansion of the tourist season. July remains the peak month with 5.2 million arrivals, representing 16.6% of the total, while August follows with 5.0 million passengers. However, the real change is found in the months outside the peak season.
In January, 758,000 arrivals were recorded (+17.1%), in February 745,000 (+11.8%), and in March 1.0 million (+7.5%), while significant increases were also observed at the end of the year, with November (+14.2%) and December (+11.3%). In contrast, during the period of May–September, increases are at lower, single-digit levels, indicating a gradual normalization of the overconcentration of demand during the summer months.
This development is linked to the strategy of extending the tourist season, increasing city breaks, and strengthening special forms of tourism, such as conference and cultural tourism.
Airports: Concentration and regional dynamics
The distribution of international arrivals by airport reveals a high degree of concentration, with the top five airports accounting for 77% of the total. The Athens International Airport remains at the top with 12,044,607 passengers (+9.0%), confirming Athens’ role as a key entry hub and city break destination.
Next is Heraklion with 4,050,378 arrivals (+6.9%), Rhodes with 3,055,817 (+1.5%), and Thessaloniki with 2,705,497 passengers, which recorded one of the highest increases (+10.2%). In fifth place is Corfu with 2,080,517 arrivals (+5.7%).
The variations across individual destinations are noteworthy. Santorini recorded a significant decrease (-14.5%), a trend that may be linked to issues of oversaturation or a shift in demand toward other destinations. Similar declines are seen on smaller islands, such as Samos and Mytilene, while in other cases, such as Kalamata (+10.8%) or Araxos (+10.0%), an increase in traffic is observed.
This overview confirms that, despite overall growth, Greek tourism is entering a phase of greater diversification, in which performance is not uniform across all destinations.
Athens: A Major Hub for International Tourism
Market analysis for Athens International Airport shows that the capital is consolidating its role as a destination in its own right. Arrivals reached 12.0 million, an increase of 9.0%, while the five main markets (Italy, Germany, the United Kingdom, France, and Cyprus) account for 40% of total traffic.
There has been a significant rise in transatlantic markets, with the U.S. recording 723,000 arrivals (+18.5%), as well as growth in markets such as Spain and Israel. At the same time, smaller markets such as Albania, Denmark, and Hungary are also showing upward trends, a fact that demonstrates the expansion of the geographic base of inbound tourism.
Thessaloniki: Double-digit growth and Balkan dynamism
Thessaloniki Airport records a strong increase, with 2.7 million international arrivals and a 10.2% increase. Germany remains the main market with 859,000 passengers, followed by the United Kingdom, Cyprus, and Italy.
Specific dynamics are shown by markets in the wider region, such as Turkey (+22.6%), Israel (+51.5%), and countries in Eastern Europe, which highlights the role of Thessaloniki as a regional hub for the Balkans and Southeastern Europe.
Regional airports: steady growth with variations
At regional airports, arrivals totaled 16.3 million, an increase of 3.1%. The United Kingdom and Germany remain the main markets, with 4.2 million and 3.1 million passengers respectively, followed by Italy and Poland.
Meanwhile, markets like Israel (+29.1%) are strengthened, while others, like the Netherlands (-5.7%) and Belgium (-7.7%), are experiencing a decline. This image confirms the shift to a more polycentric demand model, where flows are distributed differently by destination and market.
Conclusions: Development with new balances
The overall picture of international air arrivals for 2025 shows that Greek tourism continues to grow, but with new characteristics. The increase in arrivals is accompanied by an extension of the tourist season, the strengthening of non-traditional markets, and a diversification of performance among destinations.
Data suggest that the next phase for Greek tourism is not just about quantitative growth, but about managing growth, balancing destinations, and improving the quality and resilience of the tourism product.
