I dont see how it would work going into STN, it wont be cheap and though it would be for the business user i dont think STN offers that client what they want.
If it does get replaced i would think it more likely to be a LGW link wioth FlyBE though even that could be unlikely considering their NCL services.
Im with Skipness, if it does happen give it one season, it didnt even work at MAN.
