Transport Secretary Heidi Alexander has approved plans for a second runway at London Gatwick Airport.
The landmark decision represents one of the most significant aviation expansions in the UK in decades, transforming Europe’s busiest single-runway airport into a dual-runway operation capable of handling nearly 390,000 flights annually by the late 2030s.
The £2.2bn privately-financed project involves effectively moving the current Northern Runway 12 metres to bring it into regular use, as well as other developments, including extending the size of terminals. This approach allows Gatwick to maximize its existing infrastructure while creating substantial new capacity.
Massive Capacity Expansion
London Gatwick, in West Sussex, is currently Europe’s busiest single-runway airport with more than 40 million passengers using it every year. The approved expansion would dramatically increase the airport’s capabilities across multiple metrics.
Gatwick currently handles about 280,000 flights a year. The airport says the plan would enable that number to rise to around 389,000 by the late 2030s. The plans approved by Transport Secretary Alexander would include adding 40,000 more flights before the second runway opens, and 70,000 more – almost 190 additional flights per day – once it is fully operational.
The transformation would see passenger numbers potentially rise to up to 80 million annually, nearly doubling the airport’s current capacity and positioning it as one of Europe’s largest aviation hubs.
Strategic Runway Deployment
Currently, the Northern Runway is only used for taxiing or as a backup facility. The approved plan will convert this underutilized infrastructure into a fully operational runway, demonstrating efficient use of existing assets.
The second runway would be dedicated to short-haul flights, with capacity also freed up for more long-haul services from the main runway. This strategic division would allow Gatwick to optimize operations for both European and intercontinental routes.
Timeline and Implementation
The government’s suggestion that planes could be taking off from the new runway before the next general election indicates an accelerated development timeline. Such rapid implementation would require streamlined planning processes and efficient construction management.
The phased approach, with 40,000 additional flights beginning before the second runway’s completion, allows Gatwick to start realizing capacity benefits immediately while the major construction work proceeds.
National Aviation Strategy
The Gatwick expansion represents a significant element of the UK’s aviation strategy, providing substantial additional capacity in the London area without the political and environmental challenges associated with Heathrow’s proposed third runway.
The £2.2 billion investment, combined with the potential for nearly doubled passenger capacity, represents one of the most significant aviation infrastructure developments in recent UK history, fundamentally reshaping the Southeast’s aviation landscape.
