The coalition government had ruled out third runway, but the proposal just would not go away. Today, airport bosses argue the case.
Passengers using Heathrow face a rise in ticket prices under £3 billion investment plans proposed today by bosses of the airport.
Heathrow bosses will this week announce multi-billion pound investment plans for the airport.
Video. Heathrow says it has grand plans to make sure its massive new terminal opens without the chaos that surrounded the first day of Terminal 5. Baggage belts broke and staff got lost.
The new building is called Terminal 2: The Queens Terminal and will open in three months. For the past three years, it has been the biggest construction site in Europe. The cost of the rebuild, a staggering £2.5 billion and 24,000 staff will be employed in the new building.
So, as the finishing touches are being made, our Transport Correspondent Mike Pearse has been given an exclusive look around.
He spoke to John Holland-Kaye from Heathrow Airport.
While many believe another runway is needed in our region, few want it in their back yard. Although the expansion of Heathrow could create thousands more jobs, it would also bring more aircraft noise and pollution. And in some cases whole communities could be wiped out.
Chris Maughan has been finding out what the expansion of Heathrow would mean for those living under the flightpath.
Passengers at Heathrow, Gatwick, and Southampton airports are being told to expect delays due to an air traffic control problem. National Air Traffic Services says it's a technical hitch related to a changeover from night-time to daytime duties.
Due to a technical problem at Swanwick we are currently experiencing some difficulty switching from night time to daytime operation. This may result in some delays for which we apologise. Engineers are working to rectify the problem as soon as possible."
New runways must be built, that is the message tonight from the man in charge of airport expansion. Sir Howard Davies said developing Heathrow or Gatwick, and a new airport in the Thames Estuary, is firmly on the agenda.
Campaigners living beneath the flightpath say extra planes and more flights will be unbearable and nothing short of an environmental disaster. The final decision will be made at the end of the year. Our Transport Correspondent Mike Pearse reports.
Following plans to extend Gatwick and Heathrow at the Airport Commission discussion today, we asked residents in Ifield, near Crawley if they thought the plans for a new run way would affect them. Here is what they thought.
Airport campaigners hoping the Governments Aviation Commission would rule out expanding Gatwick, Heathrow or building a new airport in the Thames Estuary have been left disappointed.
Sir Howard Davies has told them at a gathering of campaigners and airport bosses new runways were needed.
Campaigners say this leaves hundreds of thousands of people living around airports blighted.
More runways in the South East must be built if gridlock in our skies is to be avoided, according to the man heading a Government review.
Today, it was confirmed the expansion of Heathrow and Gatwick and a new airport in the Thames Estuary were firmly on the agenda.
Critics gave a furious response saying more runways would be an environmental disaster.
Sir Howard Davies, who is heading the Governments Commission on the future of airports, was giving an update on his policy a year after it was launched.
Discussions about the future of the Souths airports has been getting underway today, with Sir Howard Davies saying that new, additional runways will be needed in the coming decades.
– Sir Howard Davies, Chairman of the Airports Commission
Our provisional conclusion is that we will need some net additional runway capacity in the South East of England in the coming decades. To rely only on runways currently in operation would be likely to produce a distinctly sub-optimal solution for passengers, connectivity and the economy and would also almost certainly not be the best solution in terms of minimising the overall carbon impact of flights and travel to and from airports.
The man looking at the future of airport expansion in the South is answering questions on the issue today.
Chairman of the Airport Commission, Sir Howard Davies, is looking at whether Gatwick should have a second runway, Heathrow a third or whether a new airport should be built in the Thames estuary.
The event is the first public discussion of the Commission's thoughts since its launch in November 2012.
Up to 150,000 new jobs will be created in the region if Heathrow gets a third runway, the airport claimed today. It put forward three separate locations to the Government's airport commission insisting it was in the best interest of the nation.
But around the airport it's left thousands worried about their homes and the noise. Campaigners say they will fight it tooth and nail. Here's our Transport Correspondent Mike Pearse.
He speaks to nearby residents, Colin Matthews of Heathrow Airport and London Mayor Boris Johnson.
