Athens International Airport – which is named after Eleftherios Venizelos, Greek prime minister in the 1930s – is not only the world's first BOOT project in the airport sector but also an outstanding example of successful public-private partnership. HTA/HTAC have a stake of just over 40 percent in the airport serving the Greek capital, with five percent held by a private investor and 55 percent by the Greek state. The Greek government is drawing up plans for a partial sale of its shares but no date for the IPO has been fixed yet.

Athens International Airport is a great credit to the motherland of the Olympic Games: for the fourth time in a row, it has won the OAG Airport Marketing Award for its good cooperation with the airlines.

Airline marketing is one key reason why more and more airlines are including Athens on their flight schedules. In 2008, the airport acquired two more airlines and four new destinations in Europe for its route network, which now comprises a total of 115 cities in 51 countries.

A further basis for this airport's success is real estate development within its own grounds. 2007 brought the completion of the airport's first business park. In January 2009, the new 50,000 square meter convention and trade fair centre built on another site opened for business.
