Gatwick's second runway has been given the go-ahead by the government.
The northern runway already exists parallel to Gatwick 's main one, but cannot be used at the same time, as it is too close.
It is currently limited to being a taxiway and is only used for take-offs and landings if the main one has to shut.
The £2.2bn expansion project will see it move 12 metres further away to solve the problem, facilitating 100,000 extra flights a year and 14,000 jobs.
The airport is already the second busiest in the UK, and the busiest single runway airport in Europe.
No public money is being used for the expansion plan, which airport bosses say could see the new flights take off from the second runway by 2029.
