In the wake of Chancellor Rachel Reeves giving her support for a third runway, Heathrow said in a statement the project would require policy changes including on airspace modernisation, planning and the regulatory regime.
Heathrow chief executive Thomas Woldbye said: “2025 has started how we mean to go on – serving record-breaking passenger numbers and delivering trade and investment across the whole of the UK.
More than 1.2 million passengers travelled between Heathrow and the US in January, up 8% compared with a year earlier.
Heathrow airport said it has recorded the busiest January in its history.
The statement added that Heathrow is “working with our stakeholders to finalise our plans” and intends to “submit our proposal to Government by the summer”.
