The airport is predicting a strong rebound this year despite lingering headwinds, driven by "a surge of Brits heading for summer sun".
Passenger numbers at Heathrow fell to just 19.4 million last year (year to 31 December), the lowest level since 1972. It claims to be the only European hub airport to have experienced a reduction in traffic last year, citing "tighter travel restrictions than EU countries".
Cumulative losses owing to the pandemic, meanwhile, have now risen to £3.8 billion – even after achieving cost savings running to £870 million over the past two years.
