Heathrow Airport experienced a record-breaking single day for passenger numbers in May 2026, yet the overall monthly total declined compared to the same period in 2025, according to the airport's latest traffic report.
The record day saw over 260,000 passengers pass through the airport, the highest ever for a single day in May. However, total passenger numbers for the month fell by 2.3% year-on-year, to approximately 6.7 million.
Heathrow attributed the decline to ongoing economic uncertainty and reduced business travel, though leisure demand remained strong. The airport also noted that airline capacity constraints and air traffic control issues contributed to the mixed results.
Despite the monthly drop, Heathrow remains the busiest airport in the UK, and the record day underscores the resilience of travel demand during peak periods.
