How big was LCY ever meant to become? A quick look at Google makes it seem it has reached the limits of growth, short of extending out into the Thames or Victoria docks to the west. Even then... where would the larger jets park on the apron? Was it built only for light traffic and private airport to begin with?
And although I am glad for the AMS route, any reason why? As far as I understand, LCY serves mostly the financial community and Amsterdam is not exactly a financial hub (maybe if Barkley's had succeeded in acquiring ABN Amro). Why not Luxembourg, Brussels, Düsseldorf or Geneva?
