Airportplanner - extra runways at LHR will cost a fortune and the airlines will have to pay. They aren't going to be interested in 50 pax to Carlisle or Dundee. It'll be every hour on the hour to JFK.
same as yr local multiplex 20 screens and everyone thinks you'll get all sorts of arty movies... but what you get is 15 screens showing Batman v. Thor v. Paddington starting every 15 minutes.....
