Heathrow's proposed third runway expansion could lead to a shift of nearly 15,200 aviation jobs from regional airports by 2050, raising concerns among critics who question the claimed economic benefits, despite government assertions of nationwide growth and a potential £33 billion investment in the project.

Heathrow's third runway expansion has sparked significant debate as new analysis reveals that 15,200 regional aviation jobs could be concentrated at the airport by 2050, displacing jobs from other UK airports.

The New Economics Foundation (NEF) conducted the analysis, indicating that Birmingham Airport alone could lose 7.5 million passengers annually, translating to approximately 9,500 jobs. Furthermore, an additional 6,400 jobs at other London and southeast airports may also be affected.45

The UK Government maintains that the expansion will enhance economic growth, projecting a potential increase in UK GDP by up to 0.05 percent annually. However, critics argue that these benefits are overstated, with a peer review commissioned by the Department for Transport (DfT) suggesting that it would be 'erroneous to claim a broad distribution of the gains' from Heathrow to other regions.

Heathrow's chief executive, Thomas Woldbye, has also challenged the economic modelling, asserting that traditional appraisal methods overlook the broader benefits of increased exports, private investment, and trade.

The proposed scheme involves constructing a 3,500-metre runway at an estimated cost of £33 billion, which would increase Heathrow's annual flight capacity from 480,000 to 756,000 flights. The Government aims to expedite the project, targeting completion by 2035.12

Key Insight
“The analysis by the New Economics Foundation estimates that 15,200 aviation jobs could be concentrated at Heathrow by 2050, with a further 6,400 jobs potentially displaced at other London and south-east airports. Critics argue that the Government's claims of widespread economic benefits are overstated, with a peer review stating it would be 'erroneous' to expect broad distribution of gains.”
