Unique Zurich Airport, the company that runs Zurich airport, is in talks with the authorities of Siena in Italy about the future of the local airport.
"It is correct that we are in talks with the people at Siena airport to study the future of the airport. These talks are going well but there is nothing concrete and there are no deadlines," a spokesman for Unique said.
Unique is interested in expanding its activities abroad. It is already part of a consortium that is holding exclusive talks with authorities in India about building an international airport in Bangalore, home to much of the Indian software industry.
Italian aviation sources said Unique was in the running to operate an upgraded airport at Siena, which would specialise in tourism flights. "The deal is as good as done", said an Italian source.
Operators of Siena airport, the Consortio per l'aeroporto di Siena, run the small Siena airport, which caters for military flights and private jets.
Bigger tourism planes for Tuscany currently go to Florence.
