British Airways passengers have been left concerned for their safety after it emerged that some flights are running with '70% capacity'.
Passengers have complained about packed flights and people travelling without masks, amid fears of a second peak of the virus.
BA said face masks are a "personal preference", adding that it is currently in talks over how to implement safety procedures in a post-coronavirus world.
Under current rules, the airline said facial coverings are not compulsory on board its flights. The aviation industry as a whole is struggling to bounce back from the coronavirus pandemic, with Virgin Atlantic, British Airways and easyJet all facing significant losses after a season of cancellations.
