No need to apologise for a few drams...
From the link bad bear provided that article states regional airports
with fewer than 700K pax per year are exempt. INV being the
busiest airport in the HIAL portfolio only manages I think less
than 400K per annum, and with island airports being lifelines
I doubt there will be any change for a long time.
Some of the places Ryanair operate to is another matter.
