It'll be painful for the airport in the short-term if BASCO go... and the landside access to that side of the airfield is so poor it's hard to see anyone else moving in there?
I believe that Thomsonfly have used BASCO for some of their aircraft maintenance - would BASCO leaving make BOH a less attractive base?
Thomsonfly's Prague press release is approaching Ryanair in terms of spin... loads of new destinations, because you keep chopping and changing because you couldn't get the old ones to work. Get a new aircraft in there or Ryanair will be overtaking you as BOH's 'biggest operator'.
