Davies needs to come up with a proposition--- this is what you could have ---which is not necessarily going to be what any individual airline would ideally want.
I don't see that happening - it would represent a massive change compared to how things are done at present.
The conventional wisdom is that, were there to be a step increase in capacity (i.e. from a new runway), then it would be market forces that would determine who flies where and how often, to make use of the additional capacity.
You can't tell BA, for example, that it's going to have to operate a daily service to, say, Chengdu, when the airline's view is that a better use of that particular aircraft is to add another daily JFK rotation.
