It's all part of the plot to drive GA away from self-important regional 'International Airports'.......
First put up landing fees to stupid levels, biased against light singles. Recent increases at Staverton, sorry, Gloucestershire International, being a typical example. Then insist that all GA pilots and passengers go through some 'GA terminal' complete with uniformed bottom-fondlers and toothpaste-pilferers. Then insist on 'mandatory handling' at extortionate cost. Pretty soon the word will get round - and yet another once GA-friendly aerodrome becomes a virtual no-go zone....
