London Gatwick Airport (LGW) has long been the second-busiest air hub in the United Kingdom. While it does have two runways, their close proximity has meant that only one can be used at a time, resulting in the congested facility ending up as one of the busiest single-runway airports in the entire world. For some time now, the facility has been working to get its second runway into regular operation.
The airport initially got the necessary government approval for this just under a year ago. However, resistance from campaign groups held up the process, with legal challenges against the facility’s expansion having even been made. Now, however, it has been confirmed that these legal challenges have been rejected, meaning that London Gatwick Airport can continue with its Northern Runway expansion.
Gatwick Gets The Green Light
London Gatwick Airport confirmed in a statement released earlier today that the Court of Appeal had made the “decision to reject the legal challenges to our planning permission.” These came about following the Northern Runway’s initial government approval in September of 2025. According to the BBC, lawyers representing campaign groups told the High Court in January that the plans were insufficient.
They had qualms with the fact that the environmental impact of the project had not been properly assessed in the plans and approval, as these documents only considered carbon dioxide, but not other aviation-related emissions. After losing two challenges, the BBC reported in June that the groups were considering an appeal, but this has now been rejected. Gatwick CEO Pierre-Hugues Schmit said today that:
“This ruling, from senior Court of Appeal Judges, brings to an end an eight-year planning and legal process which has carefully tested and scrutinised every aspect of our expansion plans on multiple occasions.”
How Would Dual-Runway Operations Work At London Gatwick Airport?
The main runway at London Gatwick Airport is 3,316 meters (10,879 feet) long. Paved with asphalt, it bears the headings 08R/26L, and is able to handle the largest commercial aircraft. Situated just to the north of this runway is a shorter asphalt-paved strip, 08L,26R, that measures 2,565 meters (8,415 feet) in length. For the most part, this runway is used as a taxiway due to its proximity to the main strip.
At multi-runway airports across the world with greater separation between their strips, passengers may sometimes find that their plane will land in parallel to another aircraft on an adjacent runway of the same heading. However, while London Gatwick Airport will now be able to put its plans into action in terms of getting both of its runways to be operational at the same time, parallel runways will remain off the cards.
Indeed, as detailed in the infographic above, once Gatwick’s dual-runway operations are up and running, all arriving flights will continue to only use the longer southern runway. This will also be the case for larger departing aircraft. However, smaller departing aircraft will be able to use the shorter northern runway using existing flight paths. Such operations should ease congestion at what is a very busy airport.
A Much-Needed Boost For The Second-Busiest Airport In The United Kingdom
London Gatwick Airport has long been in need of a capacity boost, with its single-runway setup having severely restricted its growth in recent years. This has also left it vulnerable to operational disruption when things go wrong, as was seen last month when a British Airways Airbus A320 suffered a nose wheel failure and blocked the runway. 14 flights had to divert, with nine declaring fuel emergencies.
The facility also expects its growth plans to have a meaningful financial impact. Indeed, Gatwick Airport estimates that, along with creating some 14,000 new jobs, the project will “deliver a £1 billion [$1.3 billion] boost to the economy every year and a comprehensive education, skills and business strategy designed to bring maximum benefits.” Now, it will be able to bring the project to life in the coming years.
