Just because Prestwick Airport hasn't been sold doesn't mean to say that it is going to close as some people desperately wish for.
Who specifically are you referring to? I can't see why anybody would "wish" for a complete permanent closure. I would like to see Prestwick Airport grow, with more Ryanair traffic and from other carriers, especially Wizz Air whoes 4 weekly flights is almost like a piss take considering any other secondary airport which is comparable to Glasgow-Prestwick like Paris-Beauvais, Oslo-Torp or Stockholm-Skavsta has several routes and several flights daily, not 3 or 4 a week! But then you have to ask yourself, why do Wizzair operate so little from Prestwick?? Ryanair competition is not the answer, Prestwick has become one of Ryanair's smallest bases and they get a lot more competiton from them at virtually any other city that they serve. There must be some other more complex reason, perhaps the lack of investment/old facillities is the reason or may be low demand, which like it or not, for a small airport like Prestwick, could well be fatal, especially if the investment to improve it and get people to use it is not there in the first place!
