Heathrow third runway plans face 'delusion or deception' warning over costs and timeline

"Heathrow has estimated that a third runway, alongside major upgrades to terminals and infrastructure, could be delivered for around £49 billion, with the first flights operating by 2035. The airport has repeatedly stressed that the scheme would be privately financed, meaning it would not require direct taxpayer funding."

"However, critics argue that the true cost of the expansion would ultimately be borne by airlines and passengers through significantly higher airport charges. Airlines have already raised strong objections to Heathrow's proposals, warning that the expansion could dramatically increase the cost of flying through Britain's busiest airport."

"The report, authored by infrastructure adviser Paul Mansell, warns that the government-backed expansion could expose both the airport and airlines to major financial risks if the project suffers delays and cost overruns similar to those that have plagued the HS2 rail scheme."

Heathrow Airport's plans for a third runway have drawn renewed scrutiny following a report questioning the airport's claims about project delivery and financing. The airport estimates the expansion, including terminal upgrades, would cost approximately £49 billion and be completed by 2035 using private financing. However, critics argue the true costs would be borne by airlines and passengers through higher airport charges. Airlines, particularly International Airlines Group and Virgin Atlantic, strongly oppose the expansion, warning it could dramatically increase flying costs. Industry estimates suggest passenger costs could potentially double. The airport plans £59 billion in capital spending during its next regulatory period, with £10 billion needed for maintenance and operations alone.
