UK business leaders are asking the public to sign a pledge demanding political support for new runways in London and the south-east, in order to support future jobs and growth in the country.
The group of companies involved in the campaign include Harrods, international manufacturer Kesslers, construction giant Mace, property firm Segro and global law firm Linklaters.
A recent survey by the Office of National Statistics revealed that approximately 59% of the UK public wants the construction of new runways and the new campaign is taking a cue from that.
According to the group, the aim of the campaign is to put pressure on politicians to make a public pledge to build more runways and commit to this in their 2015 election manifestos.
The campaign will use email and social media to gather enough support before the Airport Commission releases its final recommendations next year.
The campaign organisers also plan to stage a roadshow of events in Newcastle, Belfast, Edinburgh, Cardiff and Liverpool and will have a presence at the forthcoming party political conferences to be held in Manchester, Birmingham and Glasgow.
Let Britain Fly director Gavin Hayes said: "Often in the public debate on airports expansion, we hear loudly the concerns of those people who are against. Let Britain Fly now wants to create the space and opportunity for the 'silent majority' of people who are in favour of expansion to also have their say.
"The evidence suggests that a majority supports airports expansion, and understands the need to support jobs and growth across the country. Today, we are giving them a chance to speak out on this important issue by signing the Let Britain Fly Pledge and demonstrating to politicians that voters think this issue is of national importance."
Kesslers international director George Kessler said: "The public needs to take their opportunity to have their say on this issue, which will seriously affect the availability of employment and jobs for both them and their children."
