Olympic Airways is going to be sold to private investors in the short run.
Sabena, will be privatised (allthough not floated on the Stock Exchange) as soon as SAirGroup gets the other 49%.
If I'm correct also Aer Lingus will be privatised. However, they've stopped the sale due to some problems with their employees (the investment bank who was leading the sale has postponed it until the labor problems have been resolved).
Malev is also on the list of airlines to be privatised.
