Schiphol claims to operate Heathrow's third runway Schiphol is also helped by Air Passenger Duty levied on passengers flying from UK airports, meaning that long haul flights are frequently cheaper for passengers who change aircraft in Amsterdam. Its cheeky self-promotion will intensify pressure on the Government to tackle the problem of lack of runway capacity in the South East. Last week Sir Howard Davies, the former head of the Financial Services Authority, unveiled his team which will carry out an investigation into how Britain can retain its hub status. His team is due to produce an interim report by the end of next year and a comprehensive study after the 2015 election, a move which has led to accusations that the Government has kicked the decision on new runways into the "long grass." Boris Johnson, London's mayor, who is backing a new airport in the Thames Estuary rather than a third Heathrow runway, has repeatedly accused the Government of dithering and handing the initiative to Britain's continental rivals. A Heathrow spokesman said: "If we had more capacity these flights could be coming through the UK bringing jobs, economic growth and tax revenues. Instead the Government is outsourcing Britain's airports and jobs to our European competitors.
