The money to run HIAL comes from central Government, ie all the UK taxpayers, the money to run Dundee came from Dundee and nowhere else.
Now HIAL have Dundee, funding will come from all of us.
For info, none of the HIAL airports make a real profit, INV may make an "operating profit" but they still have massive debts to service each year.
The remainder of the airports within the group are largely operated for the benefit of the community and can't be expected to make profits.
Dundee will be amongst the latter.
