The two airlines plan for their new partnership to take off on March 30th 2014, combining slots at Heathrow.
The Government must "pull its finger out and start building", Labour said in the wake of today's raft of infrastructure announcements.
Pothole repairs and improvement plans for the A21 in Kent, junctions on the M4, the M23 Gatwick and the A27 Chichester bypass announced.
A conservation group are campaigning against Gatwick's proposal to add a second runway to the airport.
Gatwick Airport Conservation Campaign (GACC) group are against Gatwick's plan for another runway, which would make the airport as large as Heathrow.
The group have already campaigned twice against Gatwick in its bid to build a second runway.
Volunteers from the group have been giving out leaflets and recruiting members outside runway exhibitions, including Crawley and Ifield.
The GACC vice chairman, Peter Barclay, said: "Many people are confused by the airport response form which has 278 boxes which you can tick but only one well-hidden little box labelled 'None of these options' if you wish to say No to a new runway."
– Brendon Sewill, chairman of Gatwick Area Conservation Campaign
A number of local action groups, from Tunbridge Wells to Horsham, have been formed opposing a new runway - all working with GACC. For instance, in Crawley the all-Party ‘One’s Enough’ group has been re-started: it had great success in 2003 in persuading Crawley Council to switch from a position of support for a new runway to one of unanimous opposition."
There has been an increase in the number of passengers flying through Gatwick last month.
The West Sussex airport handled more than 2.7 million passengers in March - a 5% rise since March 2013.
The rise came despite a dip in North Atlantic traffic and no US Airways flights from Gatwick in 2013.
Gatwick bosses are hoping that the summer's launch of three new Norwegian Air Shuttle routes to America will help increase traffic to the region.
Last week, the House of Commons Transport Committee criticised Gatwick and its handling of the Christmas Eve crisis when flooding caused a power failure which led to flight cancellations.
London Gatwick has issued a statement to the report: “Gatwick welcomes the Transport Select Committee’s report and fully accepts its recommendations.
"Following the events of Christmas Eve, Gatwick set aside a £30 million resilience fund and immediately began projects to strengthen flood defences.
"In partnership with its airlines, extensive work has already been undertaken to improve contingency plans and passenger welfare in times of disruption.
"It is now important to focus on the future and today’s report coupled with David McMillan’s accepted recommendations will help ensure the entire airport community makes the improvements required.”
A report into the chaos on Christmas Eve at Gatwick after flooding caused a power failure suggests the disruption should be a wake-up call to other airports.
More than eleven thousand passengers were affected by the delays and cancellations in 2013. Passengers complained of inconsistent information and a lack of facilities.
A report into the chaos at Gatwick airport on Christmas Eve should be 'a wake-up call for airports across the UK' in dealing with disruption.
More than 11,000 passengers were affected by delays and cancellations after flooding caused a power failure at the airport.
A report into the problems looked at what passengers were not happy with, which included:
Lack of clarity about who was in charge
A lack of basic facilities, such as toilets and drinking water
Confusion about what expenses passengers could be reimbursed for, particularly if alternative flights had been arranged
Louise Ellman, chair of the Transport Committee said, "Many staff at Gatwick, working for the airport, the airlines, and other operators such as the baggage handlers, worked extremely hard to keep flights operating on Christmas Eve and to look after passengers.
"But the problems that unfolded were not new and the whole event should be a wake-up call for airports across the UK to improve their operational resilience.
"Airports must ensure that their contingency planning is good enough to ensure that future disruption will be met with well-drilled arrangements that are familiar to airline operators, airlines and other contractors, and which put passenger interests first."
Gatwick Airport has today revealed plans for a controversial second runway.
It would cost £7 billion pounds and open in 2025. The airport says it would be the biggest-ever boost to the local economy- £56 billion pounds and with 19,000 new jobs.
Gatwick say a third runway should not be built at Heathrow and are launching a massive campaign against it.
Our Transport Correspondent Mike Pearse reports.
The owners of Gatwick Airport have released footage of their plans to build a new runway.
The airport claims that the expansion would help the UK connect to 27 more destinations than a third runway at Heathrow, while a key architect behind the plans suggests the move could spark an Olympic-style boost for the economy of south London.
- Gatwick claims a second runway, to open in 2025, would link the UK to more destinations than a three-runway Heathrow
- Heathrow and Gatwick were shortlisted as favourites in December by the government's Airports Commission
- Commission chairman Sir Howard Davies said a new airport in the Thames estuary merited further investigation but a so-called "Boris Island" is now thought increasingly unlikely
The owners of Gatwick Airport vowed today to start building a controversial second runway by 2020. The announcement is the latest salvo in the battle between Heathrow and Gatwick to win government backing for airport expansion.
Around 4,000 households most affected by noise from a possible second runway at
Gatwick will get £1,000 towards their council tax, bosses of the West Sussexairport have promised.
The pledge involves annual compensation and is equivalent to Band A council tax. Gatwick chiefs are pressing hard for an extra runway and such an option is on the shortlist now being considered by the Whitehall-appointed Airports Commission.
– Gatwick's chief executive, Stewart Wingate
Expansion at Gatwick would, without doubt, deliver many upsides for our local community in terms of jobs and investment. But we must also recognise the negative noise impacts on local people from more flights. Gatwick's location obviously means that comparatively fewer people would be affected by a new runway. However, I believe we must do more to help those that would be affected. Under the scheme, we are pledging £1,000 towards council tax for qualifying households in the local area, if and when a second runway became operational."
One of those opposed to a second runway at Gatwick is Horsham Tory MP FrancisMaude. He addressed more than 300 residents of the village of Warnham who areobjecting to a new Gatwick flight path trial.
– Francis Maude MP, Horsham Con
Even these last few weeks, with the weather keeping people indoors and off-season traffic levels, the noise from the flight path trial has been unacceptable for local residents. When high holiday season is on us, with the warm weather enticing people outside, the effects are likely to be intolerable. So I'm urging (air traffic control company) Nats and Gatwick to call time on this trial now. We've had the trial. It's failed."
