There was a separate thread called 'Davies commission' or similar. It was set up after the event in Manchester a few months ago. It was essentially Shed and Bagso talking to themselves and died a death, but by all means, try and dig it out and resurrect it.
Personally, I've yet to meet anyone involved in airline route development who believes that MAN is a substitute market for LHR. It doesn't surprise me at all that people in the business don't engage with the debate because for many (me included) it's based on an entirely false premise.
