London Heathrow Airport increased revenue by 1.9 per cent year on year to reach £1.7 billion in the first six months of 2025, despite macroeconomic uncertainty and geopolitical “events”.
The UK hub catered for 39.9 million passengers from 1 January to 30 June, a record for the airport, which said it is on track to reach its forecast of serving 84 million passengers for the year.
This is despite a dip in Q1 passenger traffic after operations were suspended for 10 hours on 21 March due to a power outage caused by a nearby fire.
Passenger growth in H1 was driven by “strong” demand for Asia-Pacific and Middle East destinations, while transatlantic travel remained “healthy”, contributing to a 2.4 per cent growth in trade.
The airport’s adjusted EBITDA (earnings before interest, taxes, depreciation and amortisation) rose by 0.8 per cent year-on-year to £959 million in the year’s first half, compared with £951 million in the same period of 2024.
In a statement, the airport said it intends to submit a proposal for a third runway to the UK government by 31 July. The project will be privately funded and promises to “improve operational resilience”. Subject to government approval and planning permission, the runway could be operational by 2035, the airport said.
“We will soon submit our long-term expansion plans to the Government, providing the UK with the opportunity to stay competitive, boost jobs and drive nationwide growth,” said Heathrow CEO Thomas Woldbye. “Heathrow has an exciting future ahead and we are ready to get going.”
