LTN MAN
A lovely diagram , but in these harsh times who is going to fund all the expansion ?
BHX and MAN also have ongoing expansion,and the former a runway extension starting next year.
However the difference is at least they both have a fair number of full fare airlines paying there way.
LTN/STN being mostly low cost just don't get much fees,certainly Easy or Ryan Air don't want to pay anything for the privilege of going into airports.
Perhaps all the biz jets bring big funding in I don't know ?
