Heathrow Breaks Historical Record in January with 6.5 Million Passengers, Reigniting Urgent Expansion Debate
London Heathrow began the year with figures that solidify its position as Europe’s premier hub, while simultaneously reviving a structural concern that can no longer be deferred: a lack of capacity. In January, 6.5 million passengers traveled through its terminals, making it the busiest January in the airport’s history, with year-on-year growth exceeding 2%.
A Record January Despite Adverse Weather
Heathrow recorded multiple days with over 250,000 passengers, surpassing the previous January single-day record of 246,000 travelers. This achievement is particularly significant considering the month was marked by adverse weather conditions across the United States and Europe, factors that typically disrupt punctuality and long-haul flight schedules.
From an operational standpoint, January also marked a major infrastructure milestone: it was the first month in which 100% of passengers used new security lanes across all terminals. This full implementation has improved processing speeds without compromising security standards, confirming a technological transition completed during a key operational period.
Punctuality, Passenger Experience, and European Leadership
Heathrow maintains its title as Europe’s most punctual hub, a notable indicator given the high levels of continental air congestion. This operational performance was reflected in satisfaction metrics, with over 95% of passengers rating their experience as “good” or “excellent” during January. Additionally, the airport was recognized as the “Best UK Airport” for the fifth consecutive year at the Travel Weekly Globe Travel Awards.
Air Cargo: 125,000 Tons and a Vital Role in British Trade
Beyond passenger traffic, Heathrow remains the primary engine for UK air trade. In January, the airport handled nearly 125,000 tons of cargo, reinforcing its role as a gateway to international commerce.

Structurally, Heathrow supports more than £200 billion in British trade annually. By value, it manages over 70% of the UK’s air exports to non-EU countries.
Capacity Limit: Growth Falling Below European Average
Despite these robust results, new figures from ACI reveal a critical turning point: passenger growth at Heathrow is now tracking below the European average. The reason is structural: the British hub is operating at full capacity.
One year after the Chancellor’s speech highlighted Heathrow’s expansion as a central pillar of the UK’s economic ambitions, the project has once again moved to the center of the political and regulatory debate. To move forward, the airport requires key decisions from the Government and the Civil Aviation Authority (CAA) in 2026. Fundamental milestones include:
- Providing regulatory clarity.
- Publishing the draft Airports National Policy Statement (ANPS) before the summer.
- Unlocking the framework to release the private financing required for the full expansion program.
Without concrete progress on these points, Heathrow will be unable to activate the capital necessary to realize the project.
CEO’s Warning: Risk of Losing European Leadership in 2026
Heathrow CEO Thomas Woldbye was direct in his assessment:
“I am proud of the strong service, great value, and unrivaled global connectivity that Heathrow offers our customers. We remain Europe’s largest airport, but the latest figures show we could lose that position in 2026, and we cannot continue to drive growth for the UK economy without more capacity”.
Woldbye emphasized that the decisions made this year by Ministers and the CAA will be decisive in:
- Enabling the delivery of the UK’s flagship growth project.
- Securing planning permission before 2029.
- Ensuring the country has the air and cargo capacity it requires.
