Phileas, I think you go somewhat too far the other way here. Viable have talked to Air France/KLM and made some sort of deal that if they could keep the airport open, they would start flights there. A non-dominated SW airport could do very well, especially one which isn't in the middle of nowhere like Newquay. The fact that it is on a hill isn't really important as geographically there is nothing stopping it from having a runway as long as LCY's.
