The next steps to decide on the future of UK runway capacity will be outlined today, with Heathrow and Gatwick airports shortlisted for new runways.
Both airports could be possible sites for new runways to be installed by 2030.
Sir Howard Davies, Chairman of the Airports Commission will talk about the recommendations for the new runways.
London Mayor Boris Johnson's aviation adviser Daniel Moylan will also speak at the conference.
Mr Johnson is completely against a new, third runway at Heathrow and has instead approved a brand new airport in the Thames Estuary.
The commission excluded any of the estuary plans last month but have not ruled it out completely.
