Gatwick has said its expansion plans are cheaper and far more beneficial than Heathrow's.
Heathrow and Gatwick airports have both unveiled revised expansion plans to the Airports Commission in a bid to secure permission to build a new runway.
The west Sussex airport said expansion at Gatwick would deliver the following benefits:
- Will achieve £40 billion more in economic benefits to the UK than expansion at Heathrow
- Expansion will deliver more than 120,000 jobs in London and south east England
- Fewer people will be affected by noise pollution
- Around 10 million more passengers would be able to travel with a second runway at Gatwick each year than with a third runway at Heathrow
