If you are not counting Stansted you can't count Gatwick either. Both are well outside London's boundaries (Gatwick in West Sussex, Stansted in Essex). Only LHR and LCY are inside London. But so many cities have airports outside the political city boundary.
Paris Le Bourget, IIRC, has no commercial air services any longer.</font>
But... If you're counting Stansted, you should also count Luton. And up until recently, you could have counted Biggin Hill too, where the Love Air flights to Le Touquet left from.
Le Bourget is private only now. But then, Roissy and Orly are not in département 75, so you may as well also count Beauvais (BVA)... Unless you're taking Ile de France as the marker, as Beauvais is solidly within Picardy.
