London Heathrow Airport (LHR) enjoyed a record-breaking year in 2025, with the largest and busiest air hub in the United Kingdom confirming today that it handled more passengers in the last 12 months than ever before. This saw its annual passenger total rise above the 84-million mark for the first time, with 2025 coming to an end in style as Heathrow also recorded its busiest-ever December. This was one of many records to fall in 2025.
