I see Ryanair are bleating on the front page of the P&J that they would create a base in Aberdeen if the costs (& taxes) were lower, that's pretty standard fare from them.
Persuade the airport/region to lower costs/subsidise then make it difficult for the arport to generate revenue any other way due to the way Ryanair operates.
They don't want to rent any check in desks, they want to charge people to carry on anything bought in the airport shops if it does not fit in your small pre booked piece of hand baggage.
IMHO better off without them
