Infrastructures, human resources and expanding the tourist season are the necessary preconditions for a sustainable development of tourism and of air transport in Greece, Dimitris Gerogiannis, CEO of Aegean Airlines said on Monday.

Addressing an event on "Reimagine Tourism in Greece", Gerogiannis said infrastructures were extremely important for the sustainable development of tourism, of cities and of the country in general. He added that this issue cannot be analyzed piecemeal, as infrastructure does not stop at an airport or at air traffic, but includes transport, energy, water, waste management, and such.

Referring to air transport, Gerogiannis said the basic infrastructure that needs systematic effort and upgrading was air traffic control management and airports themselves.
