Gatwick second runway 'to rival Heathrow'
Gatwick Airport bosses are to begin work on detailed plans for a second runway which would double annual capacity to 70 million passengers.
The West Sussex airport's owners say they will scrutinise the options to develop the site up to 2020 and beyond.
Chief executive Stewart Wingate said it could be "affordable and practical" and a better option than new runways at Heathrow or Stansted airports.
