Unfortunately it is all fantasy.
Water finds its own level. In other words, if a route was perceived to be profitable or even viable, there would be someone operating it already. The best judges of this potential are not airport management or any other body with a "wish list" of flights, but the airlines themselves. After all, it is they who are acutely aware of the bottom line and the danger of not breaking even. And it is they who, with a few exceptions, are totally indifferent to opportunities at CWL.
The likelyhood is that none of these routes will come to fruition. It is time to stop comparing CWL with BRS. They are not in the same league. Routes have come and gone repeatedly and CWL's growth has been modest at a time of unprecedented expansion in UK aviation.
In reality, CWL has found its niche as a small regional airport. It has neither the demographic, nor the economic prosperity of other UK regions to break out of this niche.
