Gatwick have said that expanding there could be enough to add the capacity that the UK needs to stay connected. A Heathrow spokesperson said: “Heathrow is the UK’s only hub airport and competes with Frankfurt, Paris and Amsterdam for transfer passengers to support long haul routes. As the country’s most important point to point airport, Gatwick serves a different market.
“There is a clear business case for a third runway at Heathrow regardless of whether Gatwick is also permitted to expand. We do not agree with Gatwick’s stance that there can only be one new runway in the South East and we would welcome a solution in which both airports were allowed to grow to deliver choice for passengers and airlines.”
