According to INSETE’s study “International Air Arrivals: 2024–2025”, published on Wednesday (March 18), international air arrivals in Greece reached 31.0 million in 2025, up 5.9% from 2024. Athens and Thessaloniki stand out with strong growth, highlighting the appeal of city breaks, while market diversification remains a key element of resilience, as no single market exceeds 17.4% of total arrivals. The data also suggest an elongation of the tourist season, with the largest increases recorded outside the summer peak, emphasizing the importance of developing and promoting off-peak products.

The study provides detailed data on air arrivals for 2024 and 2025 based on information from the Athens International Airport (AIA), Fraport Greece, and individual airports under the Hellenic Civil Aviation Authority (HCAA). The airports covered include: Athens, Thessaloniki, Heraklion, Chania, Corfu, Zakynthos, Kefalonia, Aktion, Rhodes, Kos, Mykonos, Santorini, Araxos, Kalamata, Samos, Skiathos, Kavala, Mytilene, Karpathos, Anchialos, Lemnos, Ioannina, Skyros, Chios, and Alexandroupolis.

Data from regional airports refer to arrivals of passengers from abroad, including Greek residents returning from overseas trips. The total figures differ from those published in monthly statistical bulletins because: a) more airports are analyzed than in the monthly bulletins, b) the data are subject to revision, and c) AIA figures in the study cover all passengers, whereas the bulletins include only non-residents.
