Of course, we all know that a 3-times weekly service from Heathrow to a secondary city in China is going to contribute far more to the economy than an extra 15-20 aircraft that easyJet and Norwegian could base at LGW with an extra runway
You do know that when LHR gets the third runway easyJet will be shifting a load of Gatwick capacity round the M25 to take advantage of the fact? The reason Your London Airport Gatwick fought so very hard against LHR expansion was to prevent losing traction with EZY? You knew that, right?
easyJet are a leisure airline who serve business routes and traffic just like Ryanair, but not a business focus like a legacy. Mind you they're the same as BA short haul so enough said....
