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.¡±
