10 years from now.....proposed rail link to DUB gets built, parallel runway is live and BHD is protected by having the same owner who can cut down costs by merging various admin and training costs, negotiate cheaper contracts due to it's size, get cheaper ground equipment (snow ploughs, fire engines etc.) due to ordering in greater numbers for 3 airports....highly unlikely but a frightening proposition for management at BFS I'm sure.
Still, as I said, highly unlikely in my opinion.
