PIK's runway and it's sheer footprint are an asset and that should be the focus. The terminal however is not and all it does it spread aviation in the West of Scotland even thinner than it already has become. Thats a 1960s terminal built for housing Transatlantic traffic, not a handful of Ryanair flights to the Med. When the time comes regarding the long term future of the passenger terminal it should be demolished. Would be scandalous to rebuild at the taxpayers expense, assuming it doesn't eventually find a private buyer after all these years.
