The PIK runway is a national asset.
Without wishing to dabble in the world of Scottish politics...
PIK's runway is probably a national asset for Scotland, but less so for the UK, with ca. 3000m runways available at MAN, EMA, BHX, STN and LHR it's value for the UK is somewhat less.
Of those 3000m runways, only LHR could be said to be at capacity, and is likely to remain the only one of the list for the foreseeable future.
