London's Heathrow Airport said passenger numbers in August were down 81.5% compared to last year.

It also repeated its call for the UK government to introduce testing as an alternative to the country's 14-day quarantine rule. 

Heathrow, which before the Covid-19 pandemic was the busiest airport in Europe, said North American passenger numbers were down 95% compared to last year as the 14-day quarantine rule deters long-haul travel. 

"Heathrow urges the government to introduce testing as an alternative to 14-day quarantine to protect millions of jobs across the UK and to kickstart the economic recovery," the airport said in a statement today.
