Heathrow Airport has warned that its planned third runway might be delayed to 2039 due to planning and regulatory challenges, pushing back from the original target of 2035. The project, estimated at £49 billion, faces opposition from environmental groups and local residents but is supported by the government for its potential economic benefits, including creating around 100,000 jobs. The Department for Transport acknowledges the timeline's ambition but remains committed to working with stakeholders on the project’s progress.

Story summary
Andy Burnham, the UK Prime Minister, has declined to support plans for a third runway at Heathrow Airport, citing the need to consider local opinions first. The project, which was initially set to be completed by 2035, is now expected to open in 2039 due to delays and regulatory challenges. Burnham's stance contrasts with his predecessor Keir Starmer’s support for the expansion, which is projected to create at least 108,000 jobs but faces significant opposition from environmental groups and communities concerned about pollution and climate impacts. Despite these challenges, Heathrow aims to secure planning permission by 2029, after which construction could take a decade. Burnham's reluctance to endorse the project further casts doubt on its future as it faces ongoing debates in Parliament and scrutiny over compliance with UK’s legally binding climate targets.
