Athens International Airport is not only the world's first BOOT* project in the airport sector but also a good example of successful public-private partnership. In February 2024, within the framework of the IPO of the Greek capital's airport, AviAlliance increased its stake to just over 50 percent, making it the airport's majority shareholder. 25.5 percent is held by the Hellenic Corporation of Assets & Participations, while just under 24.5 percent is in free float. Already in 2019, the concession was extended by a further 20 years until 2046.

The airport serving the Greek capital, which commenced operations in 2001, has been the frequent recipient of awards: Athens International Airport was recently highly commended at the prestigious ACI EUROPE Best Airport Awards 2024 in the category of airports with 25 to 40 million passengers per year.

In spring 2020, the quality of stay for passengers at Athens International Airport was further enhanced when an expansion of the main terminal building was opened. As well as additional check-in counters and an enlarged area for passport control, numerous stores, a wide range of catering outlets, and new lounges offer passengers even more comfort and convenience.
