I don't disagree with anything you've said in your response. The context of my post was a little unclear.My take on this is there is no point on holding out for an airline to come to Cardiff on the basis of having a slightly longer runway than Bristol airport, or by hoping passengers will revolt from Bristol because of overcrowding. Cardiff airport needs to find its own way and not rely on the shortcomings of competing airports. While the facilities are underused the airport needs to capitalise on the positives this brings by focusing intensely on customer service. If the airport can then attract a new based operator such as Ryanair they will be able to build up passenger numbers to reach the all important critical mas which in turn will provide more growth opportunities.
Also @Samdorob Welcome to Forums4airports, good to have you with us!
All businesses look for opportunities in all forms of business growth. The factors you've identified are typical of organic growth. You're quite right in that CWL has more control and influence over its organic growth opportunities and therefore should do all it can to maximise the potential benefits.
What I was thinking about was what factors may CWL be able to use or benefit from for strategic growth. It seems WG is reluctant to sell or attract an outside investor in the airport (and even if they did, that's no guarantee of success), so I was just suggesting what I thought was the most likely of the other potential strategic growth factors that may occur.
I think just about everyone who posts on this forum wants CWL to be successful. I certainly do - as well as being a reasonably regular passenger, I spent the first 10 years of my working career at the airport (seems a long time ago now, though!
