The Government has easily won a vote on controversial plans for a third runway at Heathrow.
Support from Labour MPs helped push through the proposals to expanded Europe's busiest airport with an overwhelming majority of 296.
Jeremy Corbyn's party is officially opposed to the move but allowed a free vote on the measure that is backed by unions like Unite.
Transport Secretary Chris Grayling said support for the new runway would "clear path to our future as a global nation in the post-Brexit world".
He said: "This is a really important moment in the history of this House and the history of this country."
Boris Johnson, a long-time opponent of expansion, missed the vote as he was in Afghanistan.
The Foreign Secretary, who could have been forced to quit the Government if he had voted against the Government, was mocked for failing to appear with MPs shouting "where's Boris?"
Tory former international trade minister Greg Hands, who resigned from Government to oppose Heathrow's expansion, said the plans were "fundamentally flawed".
"But this vote is also about integrity and about the pledges we make to our electors. It is to be regretted it's now not a free vote but I urge colleagues to vote against this proposal tonight."
Shadow transport secretary Andy McDonald outlined Labour's official opposition to Heathrow expansion and accused Mr Grayling of making "a complete shambles of a vital national project".
Shadow chancellor John McDonnell, speaking from the Labour backbenches, warned that villages which have existed for 1,000 years will be "wiped off the face of the earth" by Heathrow expansion to enable a company to maximise its profits.
He said: "There are human costs to this decision that this House needs to recognise and contemplate before they vote tonight to worry and blight my community once again on a programme that will never - pardon the pun - take off."
