This site was very popular with CWL aficionados until a couple of years ago. In fact, CWL was then the second most discussed airport after LBA.
Since then numbers have dwindled to the point where the former posters rarely if ever visit let alone post.
I notice the same thing is happening on the Dried Plum which again used to be very strong in the CWL thread.
I suspect most posters have retreated to the W A N site which is fine up to a point but that site is full of people preaching to the converted which is why it's good to see you spreading your message here and possibly on other sites as well.
It might actually be helpful and constructive to hear the views on CWL from those with an interest in civil aviation who aren't as close to the furnace as the W A N members and perhaps view the subject more dispassionately.
There seems little doubt that CWL is under-served and is under-performing, but it is by no means the only UK regional airport that has under-performed in recent years.
I detect a feeling in too many people that they believe CWL should be outperforming merely because it's the capital city of Wales. Life isn't like that and CWL must compete on its merits as a UK regional airport.
Whilst the Cardiff city region is economically vibrant and successful much of the remainder of South Wales is not which effectively reduces the size of the realistic catchment which is relatively modest overall anyway.
I sincerely wish you well with your campaign but I wonder if some of the people who have signed your petition are in danger of losing a sense of proportion as to what they think CWL ought to be.
The same thing is happening with Plymouth. I've just read an article in the local press there concerning a petition being circulated demanding the closure plans be halted with the caveat that if PLH was seriously expanded it could become a top English regional airport - that sense of proportion again, or rather a lack of it.
