Gatwick Northern Runway Cleared After Court of Appeal Dismisses Final Challenge; Analyst Says UK Capacity Problem Is Mismatch, Not Shortage
Why It MattersThe approval adds capacity at an existing airport using current land, which sharpens the question of whether UK constraints lie in total runway numbers or in where and when airlines can operate.
Gatwick Airport is set to become a two-runway airport after the Court of Appeal dismissed the remaining legal challenge to its Northern Runway project in August, following UK government approval in 2025. The plan moves the centreline of the existing Northern Runway 12 metres north and includes associated infrastructure works, allowing a runway that already exists to be used routinely alongside the main runway. The privately financed development is expected to cost more than £2 billion and could ultimately enable the airport to serve up to 80 million passengers a year.
Ivan Stevenson, associate professor of aviation management at Coventry University, considers whether the approval means the UK faces a capacity crunch. Gatwick handled 42.8 million passengers in 2025, fewer than the 46.6 million in 2019. The airport is also raising the productivity of its existing runway, lifting maximum scheduled movements from 55 per hour in 2025 to 57 in 2026. Stevenson argues the UK does not simply have too few runways; the problem is having enough capacity in the places, at the times and in the markets where airlines and passengers value it most.
Stevenson cautions that more passengers and aircraft movements are not automatically synonymous with economic growth. In 2024, overseas residents spent £32.5 billion visiting the UK, while UK residents spent £78.6 billion travelling abroad, and aviation capacity facilitates outbound tourism as effectively as inbound. He notes the Northern Runway adds capacity to an established airport using largely existing infrastructure and land, with financial risk resting mainly on its private owners rather than the taxpayer.
