Strong momentum for further increase in arrivals from abroad is recorded by the data of the INSETE airdata tracker for September and October.
Overall, airlines have scheduled 4.7% more seats on inbound flights to Greece than last year, a development that reinforces the expectation of a new record in arrivals and revenue in 2025.
Thessaloniki is emerging as the fastest-growing destination, with a 11.8% increase in scheduled seats for the two-month period, while in the seven-month period it has already recorded a 9.3% increase in international arrivals. Athens follows with a 6% increase in available airline seats, after a 9.5% increase in the first seven months, according to the airdata tracker.
Strong performance is also expected in Heraklion (+5.1%), Corfu (+8.9%), Chania (+4.9%), Kos (+3.8%), and Kalamata (+10.6%). At the same time, smaller airports, such as Aktio (+15.2%) and Samos (+8.1%), reinforce the image of a more extensive geographic dispersion of the tourist flow.
In contrast, Santorini remains a negative exception, with a 16.3% decrease in scheduled seats for the two-month period, following a 14.5% drop in the first seven months. In Mykonos, the available positions are marginally reduced (-0.3%), with a trend of stabilization.
Overall, the airdata tracker estimates that nearly 13 million travelers will visit Greece in September and October. This translates to an annual forecast of 37–37.5 million arrivals, up from 36 million last year. Per capita spending, which increased to 622.7 euros (+10.1%) in the first half, supports the prospect of steady or even increased revenue.
The message is clear: the Greek summer is no longer limited to three months, but extends to a “fourth and fifth month” of high season, with the airdata tracker confirming the acceleration of the tourist wave.
