Virgin is to move into the domestic market for routes in and out of Heathrow - and that could spark a price war with British Airways.
Clues on the future of airports in the south may be revealed today, including whether new runways or airports will be built.
Heathrow and Southampton are scrapping the over-arching BAA name after the airport group has been forced to sell a number of airports.
Comedian Alistair McGowan explains why he is attending the rally.
Boris Johnson today urged the Government to resist the "great Moloch of aviation capacity" and rule out a third runway at Heathrow before the next election. At a rally against expansion, he said it would be "totally nuts" for the Conservatives to go to the polls without having buried the idea.
He said: "It is just too difficult to deliver - 15 years at least it would take to bring about.
"Above all you would be inflicting noise pollution not just on west London but on huge parts of London that don't even know they are going to be affected.
"That is not the right way forward for the greatest city on earth."The protest in Barnes, west London, attracted around 1,000 residents who live under the airport's flight path.
Mayor of London Boris Johnson will today attend a cross-party rally against the highly controversial proposal to build a third runway at Heathrow airport.
Organisers say they expect thousands to turn out for the protest in Barnes, west London, to voice their opposition to expansion of the travel hub.
The Mayor has previously accused David Cameron of kicking the matter "into the long grass" by delaying an independent report on the future of aviation until after the next election.
He favours a new "Boris island" airport in the Thames Estuary or possible expansion at Stansted.
Former transport secretary Justine Greening is expected to make her first speech on Heathrow since she was moved to international development in September's Cabinet reshuffle amid speculation that it was due to her stance on the issue.
Boris Johnson, Zac Goldsmith and a number of MPs will attend a rally in Richmond against the expansion of Heathrow Airport later today.
Thousands of holidaymakers will be getting partial refunds - after being told the new Dreamliner planes won't be ready in time for the busy summer season. Today, Boeing said the Dreamliners can now fly, although it doesn't know when. Transport Correspondent Mike Pearse reports.
Boeing today confirmed the safety problems with the 787 Dreamliner have been resolved but can't say when British airlines will fly them. We have an interview with Larry Loftis from Boeing.
The company say they are working as fast as possible to resume deliveries. It's not expected that Thomson, the UK launch airline, will get them in time for the busy summer season. Thousands of passengers had booked and paid a £10 supplement to fly on the planes.
British Airways is to buy an extra 18 Dreamliner planes with a major boost to the local economy.
The deal is thought to be worth more than £3bn. Many parts for the Boeing 787 are made in the South and shipped to America where the plane is assembled.
The news has just been announced by BA parent company International Airlines Group. British Airways 787s will be powered by Rolls-Royce Trent 1000 engines. The engine order includes a comprehensive maintenance package with total care agreement.
Responding to the publication of Heathrow Airport’s future investment plans and charges for the period 2014 to 2019, Virgin Atlantic Chief Operating Officer Steve Griffiths said:
– Virgin Atlantic Chief Operating Officer Steve Griffith
Virgin Atlantic is totally committed to improving the passenger experience at Heathrow. However, we believe this can be done without a repeat of the incredibly steep price rises we have seen in airport charges in the last few years. Prices at Heathrow are triple the level they were ten years ago. Clearly this is a concern for all passengers travelling through Heathrow, and all airlines operating there.
Passengers using Heathrow face a massive rise in airport charges to fund a £3bn investment programme, it has been revealed this morning. The move sparked an angry reaction from airlines who say fees should be going down in real terms - not up.
Fees could rise by 25 per cent in seven years, the airport owner said in a consultation document. Airlines and the CAA will now be consulted on the plan. Charges for each passenger will go up from around £20 to almost £25 per person.
The plans include the completion of Terminal 2 and the early works on extending the building; the development of a new integrated baggage system; and the construction of new taxiways and stands which will allow Heathrow to accommodate more of the most modern aircraft.
The Institute of Directors (IoD), which represents the business community, has called for the government to extend the HS2 line to Heathrow Airport.
– Corin Taylor, Senior Economic Adviser, IoD
Air and rail needs to be much better connected, and so it is very welcome to see the Y-network serving Manchester airport directly.
But by the same token it is disappointing to see a direct connection to Heathrow left out altogether.
If the Davies Commission recommends that Heathrow should remain the UK’s main hub airport, then the first section of HS2 ought to run through Heathrow, not around it.
