Only time will tell whether CWL actually grows to a decent regional airport (i.e around 2MPPA) or become a housing estate. However, despite the sceptics, this could be what CWL needs and that is a change of ownership. Abertis have run CWL into the ground since 2008, and others have also mentioned the situation at BFS. Yes, we can all moan about taxpayers money being spent, but don't forget that CWL can also deliver a nice little profit to the taxpayer, only making a loss last year (2011), but profited in the years before that.
However, taxpayer money needs to be well-spent on the airport, not nice new seats for the departure lounge for the few people that use it daily on winter months. Build an M4 connection, at least listen to the CBI and others who believe that this could add an extra weapon against BRS. Wouldnt that have been a more sound investment of £100m though ?
