A number of investment groups are eyeing the possible purchase of Prague Airport, according to a Czech report.
The government hopes to privatise the airport in the next two years
Australia's Macquarie Bank and German groups Hochtief and Fraport are among the interested parties, said weekly magazine Tyden.
Prague-Ruzyne airport is currently in the hands of the Czech government.
It has been expanding in recent years, handling 11.5 million passengers in 2006, while it has set a target of 20 million passengers by 2020.
A new terminal was opened a year ago - but a new runway is needed to reach its passenger number goals.
"It is an interesting opportunity for us," Hochtief Airport spokeswoman Donatella Gasser told the magazine. "Prague airport has great potential."
Meanwhile, Macquarie - which owns airports in Europe, including Bristol - has also expressed an interest -according to Tyden.
"We are major airport investors and that is why we examine all the possibilities that come up around the world," spokeswoman Alison Jefferis said.
Wolfgang Schwalm of Fraport, which owns Frankfurt airport, said the firm was looking for "a transaction in the European space".
