February 2026 passenger numbers (5,819,080) marked Heathrow Airport’s busiest February on record. Monthly passenger data from October 2024 to February 2026 highlighted consistent high volumes and clear seasonal trends. Summer months delivered the strongest performance, with July 2025 recording 7,981,137 passengers and August 2025 peaking at 8,035,996 – the busiest month in recent years. Shoulder months such as April to June and September to October regularly exceeded 7m travellers, while winter months (January and February) remained quieter, though still robust.
Notably, February 2026 saw 5,819,080 passengers, marking Heathrow’s busiest February on record. Year-on-year comparisons show modest growth, such as October 2025 (7,365,772) compared with October 2024 (7,214,853).
For the full year 2025, Heathrow handled a record 84.5m passengers, surpassing 84m for the first time and exceeding the pre-pandemic peak of 2019. This represents a 0.7pc increase on 2024 and cements Heathrow’s position as Europe’s busiest airport. December 2025 was also the airport’s busiest December ever.
The strong rebound reflects sustained demand for both leisure and business travel, improved operational efficiency, and Heathrow’s role as the UK’s primary global hub. With capacity constraints limiting faster growth, the airport is forecasting around 85m passengers in 2026 while investing heavily in passenger experience.
Peak months were, expectedly, July 2025 (7,981,137) and August 2025 (8,035,996) were the strongest, reflecting the height of the European summer holiday season, but the shoulder months of April–June and September–October consistently delivered solid volumes above 7m. January and February remain the quietest (around 5.7–6.5m), turning in a new record for February.
Heathrow has made a robust recovery since the COVID-19 pandemic lows of 2020–2021 (when annual passengers dropped below 20–22m). Key milestones include:
- 2019 (pre-pandemic peak): 80.9m passengers.
- 2024: 83.9m passengers, already well above 2019 levels.
- 2025: Record 84.5m passengers, the busiest year in Heathrow’s history, up 0.7pc on 2024 and roughly 4.4pc above the 2019 benchmark.
The airport outperformed the previous year in nine of twelve months in 2025, set a new busiest-day record (over 270,000 passengers on 1 August), and achieved its busiest December on record. Early 2026 data (January 6.46m and February 5.82m) continues this positive momentum, with February setting another monthly record.
Heathrow has now fully recovered from the pandemic and is operating near capacity. Growth has become more incremental (0.7pc in 2025), and forecasts point to around 85m passengers in 2026. This strong rebound has been supported by robust leisure demand, improved operational performance (e.g., faster security and baggage handling), and Heathrow’s position as Europe’s busiest and most connected hub.
November and December 2025 showed healthy volumes, with December 2025 (7,188,658) contributing to the airport’s busiest December ever.
