About 83.9 million passengers travelled through Heathrow’s terminals in 2024, the airport has said.
This record-breaking number is 4.7 million more than in 2023 and 3 million more than the previous annual record in 2019, before the pandemic.
Heathrow forecasts it will serve 84.2 million passengers this year.
It added it would be investing over £1bn this year to make the airport fit for the future.
