Heathrow Airport reports that it handles fewer passengers than a year earlier despite achieving a record day in May. The airport says 7.1 million passengers pass through its four terminals during May, which is down 1.2% compared with the same month last year. The accounts describe the May total as coming alongside a standout individual day, but the overall month figures still show a slight year-on-year decline. The reporting across outlets is focused on the passenger throughput for May and the comparison with last year, with no additional details cited about the reasons for the drop. Overall, the available information indicates that while Heathrow reaches at least one peak day during the month, cumulative passenger numbers remain marginally lower on a yearly basis.
