Don't be silly, Chopin cannot expand, ie No more new runways.
As it stands, Chopin is only busy because of low cost flights. Relocate them to Modlin after expanding it, and Chopin is more than enough for business-orientated travel as well as higher yielding leisure travel.
The CPK has no potential because it's in the wrong place. Helsinki works for Asian traffic because it's the closest airport to Asia, while Istanbul and the ME3 hubs work because they can reach anywhere in the world with one connection. Warsaw doesn't have that advantage, which is why the CPK is just a Gierekist white elephant.
Just a continuation by the post communists in PO to privatise the last remaining goverment assets.
Do try and stop repeating garbage from the right wing media. LOT was in trouble for many reasons, not least the fact that it had an old fleet and people who were frankly miserable old dinosaurs. Tusk didn't save LOT, it was the state aid that did that. Now LOT is a haven of junk contracts and fake self employment, so it's hardly a success.
Still, perhaps you can tell us why a government-controlled company has become a bastion of junk contracts.
