Heathrow Airport's third runway may be delayed to 2039
Heathrow has said its third runway might not open until 2039, four years later than the government's original 2035 target. The delay has put fresh attention on whether the project still has political backing.

01What happened
Heathrow Airport has warned that its planned third runway could be delayed by four years due to planning and regulatory hurdles, pushing a possible opening to 2039. The airport said it hopes to secure planning permission by 2029 and then open the runway within a decade. The government had hoped the runway, estimated to cost £49bn, would open by 2035. The Department for Transport said the timeline had always been ambitious. The project requires a parliamentary vote that could reportedly be delayed until 2027. Plans involve demolishing hundreds of homes, diverting rivers and rerouting the M25 between junctions 14 and 15 through a tunnel. The airport currently operates with a cap of 480,000 flights a year. Expanding would create an estimated 100,000 jobs.

BBC News
Read the original· bbc.co.ukHow they framed it
The BBC frames the delay as an operational and planning update from Heathrow, with the airport expressing confidence in the project's benefits and the government acknowledging the timeline was always ambitious.
In their words
Heathrow Airport has warned that its planned third runway might be delayed by four years due to planning and regulatory issues. The airport said its 'core scenario' had always been to open a new runway within a decade of securing planning permission. A DfT spokesperson said: 'The timeline has always been ambitious. We'll continue to work with promoters, including Heathrow, and all other stakeholders at pace.' A Heathrow spokesperson said: 'The benefits of expansion can be felt from today. At least 108,000 new jobs and billions of pounds invested in supply chains in every part of the country.'
The Guardian
Read the original· theguardian.comHow they framed it
The Guardian frames the delay as a political uncertainty story, focusing on Andy Burnham's refusal to answer questions and the mixed reactions from unions and environmental groups.
In their words
Plans for a third runway at Heathrow are once again up in the air after the prime minister refused to say whether he backs the 'contested' project which is delayed by up to four years. Burnham, who has previously criticised the expansion, said he did not want to 'jump straight in' before considering the results of a public consultation. Tony Bosworth, climate campaigner at Friends of the Earth, said 'putting the start date back four years makes the already dubious economic case for expansion even more questionable.' Warren Kenny, GMB London Regional Secretary said: 'Every year of dithering is a year of apprenticeships not started, contracts not signed and wages not paid.'
03Where they differ
The two outlets cover the same delay but emphasise different aspects. The BBC focuses on Heathrow's planning timeline, the government's response and the project's economic benefits, including job creation and investment. The Guardian leads with political uncertainty, highlighting Andy Burnham's refusal to answer questions and the mixed responses from unions and environmental campaigners. The BBC does not quote opposition groups, while the Guardian does not include the Department for Transport's comment. Both report the delay to 2039 and the 2029 planning permission target.
