How about building at least one parallel runway?
Are there any investor willing to provide funds ? I didn't hear about any. Or are you saying that huge amount of our tax money should be spent, so in the future we can avoid such horrible incidents as closing down the airport for 6 days once a decade ? Wow, you're such a brainer ! Run Forrest, run ! Your vast wisdom is chasing you.
Alternatively they could do the runways one at a time: not idea from a flying point of view but better than shutting the airport.
Wow, so apart from writing some texts about restaurants, you are also a world class engineer specialized in runways pavement ! You must be If you know better how nad when such things should be done.
But clearly you have no idea at all what those costs will be
You are right, I've got no idea about the costs. Could you then enlighten me instead of over exploiting again the pathetic "you don't like It because It makes Poland look bad" stuff ? I've got no idea, simply see an article where people responsible for that issue say there is no better solution and people from the travel industry criticize It (no comments from independent experts) so unlike you, I'm not so sure that the latter must be right. If you are, then I think we will soon hear much more detailed alternatives, not only some guesses you have presented so far.
Or maybe you simply have no idea about this issue and posted It to spoil the air around as that seems to be the only entertainment in your little, silly life ? Which one is that, Harry ?
