Given that the SC will only relate to the issues concerning operating into and out of the airport I would only anticipate it coming into play were an airline starting routes from said airport for the very first time, i.e. it is emphasising new airport rather than new route
If that's the case then it really does look like an a**e-covering operation. Can anyone name a single airport in the UK which doesn't currently have commercial services but might in the future? They're all covered now. Only places I can think of are Cambridge, Carlisle and Swansea.
