The Government's decision to build a third runway at Heathrow has received a mixed reaction from leading airline chiefs, who variously branded it "good news", a pricy risk or a "piecemeal" expansion that does not go far enough.
Willie Walsh, chief executive of British Airways owner IAG, said his group was "pleased" a decision had been made but warned: "The cost of this project will make or break it."
He added: "Heathrow want it, argued for it and now must ensure it's the UK and the travelling public who get the benefits from the runway, not the airport's owners."
Ryanair chief executive Michael O'Leary said choosing between Heathrow and Gatwick was the wrong approach.
"The best way to deliver additional runways in a timely and cost-efficient manner is to approve three additional runways - one each at Heathrow, Gatwick and Stansted."
But Carolyn McCall, chief executive of easyJet, offered the largest support.
"This is good news for UK consumers and businesses and will help ensure that the UK is better connected to the rest of the world," she said.
Tory MPs are taking lumps out of each other on Heathrow, grammar schools and - above all - the true meaning of Brexit.
Environmentalist Goldsmith called the move "catastrophic" - and announced he will now stand as an independent in protest.
The expansion of the London airport will affect the whole of the UK, with more domestic routes, while impacting air fares and house prices.
