Ryanair won't come to it's rescue, 20 years service or not. It won't attract another volume carrier for numerous reasons. So it rests on cargo, training and military revenue along with the odd BA diversion. It's infrastructure is falling apart and must cost god knows to upkeep? So failing a miracle, it will go through the motions or die a death. It holds no strategic importance and hasn't done for years. If Scotland gets independence, PIK will be seen as a luxury that the taxpayer can't afford. There's nothing cheap about Nationalism.
Waiting for the backlash, but I remain to be convinced otherwise. On the other hand, as a commercial pilot, I'd be sad to see PIK go. The Ayrshire coast is always wide open when GLA and EDI are fogged out!
