The organisation, which launched last November to lobby for the building of new runways in the South East, is hosting invite-only events at the Labour, Conservative and Liberal Democrat party conferences.
As well as sponsoring the events, Cicero founder Iain Anderson and CEO Jeremy Swan will join a line-up of speakers that includes leading figures from London First, the British Chambers of Commerce London First and the Institute of Directors.
Referencing the agency’s international presence, which includes offices in London, New York, Singapore and Brussels, Anderson told PRWeek the group’s aims "aligned with our needs and those of our clients".
"The central message is that politicians need to get on with delivering more capacity and that is something we’re right behind."
The move was also a "clear statement" that Cicero had moved beyond its former focus on finance, he added.
"We increasingly work with clients across all sectors of the economy and this demonstrates our interest in conversations around infrastructure and transport."
Earlier this week, the option of building a four-runway airport in the Thames Estuary, which has been heavily backed by London Mayor Boris Johnson, was dropped by the Government-backed Airport Commission, which is looking into the best options for future expansion.
