Airport locals have won a three year extension to the ban on night flights from Heathrow, Gatwick and Stansted today.
The ban was due to expire next year but it has now been rolled over until 2017 after a consultation.
The announcement means the Davies review into aviation - which is already looking into ways to increase capacity at London's airports - will have to consider a long-term plan for the future of night flights.
The government is even considering extending the ban so it applies to the noisiest aircraft.
London Mayor Boris Johnson has given his blessing to the new six-runway option for a Thames Estuary airport, saying:
“This is further welcome argument in favour of the feasibility of having a new hub airport in the Thames estuary.
With so many options available for a multi-runway hub airport in a new location, it would be folly for the Airports Commission to give countenance to the prospect of expanding Heathrow, the most noise-polluting airport in Europe.”
A new plan for an airport on the Thames Estuary has been unveiled - with six runways instead of the four originally proposed.
Plans for a Thames Estuary solution to London's airport capacity problems have been dubbed 'Boris Island' after the Mayor expressed his support for them.
The plans have been drawn up by Testrad - the consortium set up by the Mayor to look at Thames Estuary proposals. The new airport would be called 'London Britannia' and sit on a purpose build island off the Isle of Sheppey in Kent.
Bigwigs from Schipol Airport in Amsterdam and Chicago's O'Hare will be taking part in a discussion of the competitive challenges faced by large cities in growing their vital air links to global markets.
Mayor Boris Johnson has previously voiced his anger that any further delay in establishing a proper aviation strategy for the south east will give the advantage to continental hubs.
Schipol is expected to outstrip Heathrow in terms of passengers and flights within a decade. Last year they launched an aggressive advertising campaign, marketing itself as Heathrow's third runway.
In expanding to six runways Chicago's O'Hare has faced many of the challenges, both political and financial, that are now being faced in the south east.
Representatives from Schipol and O'Hare will be joined by Daniel Moylan, London Mayoral Adviser on Aviation Policy and the CEOs of both Heathrow and Gatwick airports.
