I respectfully take onboard all the above posts. I am not in airline management; I fully accept that I'm not the world's leading expert on airline economics.
I must say however, that I think you've missed my point. What I'm saying is that there is absolutely no point in ARTIFICIALLY keeping the low cost carriers out of the market. If the businessman still wants to pay €300 for all the facilities you mention, then the market will support his doing so. What happens at the moment (at many airports) is that the rest of us end up subsidizing him - which is in my opinion plain, straightforward wrong!
