Former local, PIK was my "team". Local loyalties do credit.
PIK only ever worked in a monopoly environment. Underperformed against Renfrew, lost most short haul traffic to Abbotsinch in later years, lost the long haul in 1990. Bounced back and made money when Ryanair's (almost) whole Scottish operation was at PIK, died on it's arse when that market expanded to include GLA/EDI.
Easy to damn the management, BUT they are paid to go through the motions. No serious industry professional believes PIK can be turned around in the same way no one really thought a transatlantic monopoly for Scotland was best served via an airfield on the west coast with no other flights. It's political theatre, they get paid loads for being seen to be looking for a solution no one thinks is out there. It keeps the locals happy and buys the vote. As other airfields have become more competitive, PIK loses more market share. As for the physical state of the terminal, it's going to be a 1960s long haul transatlantic operation until it falls down, which given the winter gales, could be any year now.
Nothing will change now, it will limp on taking money from the public purse until the sun dies.
