Over 6.3 million passengers traveled through Heathrow in January, fueled by a surge in trans-Atlantic travel and ongoing discussions for a third runway.
Heathrow Airport has recorded a significant milestone in passenger traffic, with 6.3 million individuals passing through its terminals in January 2025. This figure marks a 5% increase compared to the same month last year, indicating that the surge in air travel following the pandemic has not yet plateaued.
These figures are the first to be reported since Rachel Reeves expressed support for a potential third runway at Heathrow, a development that could increase the airport’s capacity to accommodate up to 140 million passengers annually.
January marked the eleventh consecutive month in which Heathrow averaged more than 200,000 passengers per day, with trans-Atlantic routes being a primary driver of this growth.
Specifically, more than 1.2 million passengers traveled between the UK and the United States during that month, reflecting an 8% rise compared to January 2024.
In addition to passenger traffic, Heathrow handled nearly 120,000 tonnes of cargo in January, a volume that is twice that of all other airports in the United Kingdom combined.
Thomas Woldbye, CEO of Heathrow, commented on the record passenger numbers, stating, "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." Furthermore, he noted the UK Government’s indication of support for expanding Heathrow and emphasized collaboration with Ministers to encourage necessary policy changes for the airport's growth plans.
Heathrow's management has welcomed recent expressions of support from the Chancellor regarding the third runway.
To expedite the delivery of this project, policy changes related to airspace modernization, planning reforms, and regulatory adjustments will be essential, according to airport officials.
A proposal is expected to be submitted to the Government by summer 2025.
In a coordinated effort underscoring their concerns, Virgin Atlantic, International Airlines Group (IAG), the Heathrow Airline Operators’ Committee (
AOC), and the Arora hotel group have jointly urged the Civil Aviation Authority (CAA) to undertake a comprehensive review of Heathrow’s regulatory framework.
They argue that such a review is necessary to enhance consumer benefits and bolster the UK economy, particularly in light of Heathrow’s status as the country’s only hub airport and the largest in Europe.
