I think you may be wasting your time and effort Shed with some of the naysayers. As an aside, I'm not sure why a regular contributor on the BHX thread, who posts only very occasionally on here, should be telling us what we should and should not be discussing. I wouldn't dream of doing that on the BHX thread despite making the odd post.
Aimed directly at me - without a doubt!
However I have an interest in commercial aviation in general, rather than being a willy-waggler for a particular airport - you will see I have posted in numerous threads, not just BHX - check out EMA, CWL, NCL, BRS - and probably a few other too.
Tumble-weed is an excellent description of the way some threads go, and I too would think that the best place for such discussions lies not with any particular airport thread, but with a general one covering the relationship of non-London airports with the rest of the UK. I think's there's already been one set up, which is good move.
