The International Air Transport Association (Iata), which is the representative body for the global airline industry, has urged all air passengers to comply with instructions and wear face coverings during their journey. The wearing of such coverings is one of the major recommendations of the International Civil Aviation Organisations’ (ICAO’s) guidance for safe air travel during the Covid-19 pandemic. The ICAO guidance was drawn up in cooperation with the World Health Organisation (WHO) and national governments. (ICAO and WHO are both specialist agencies of the United Nations.) It provides for a multilayered approach to ensuring safe travel during the pandemic, and the wearing of face coverings is one of these layers. Iata pointed out that research by the University of Edinburgh in the UK had established that properly worn face coverings reduced the forward spread of droplets from the mouth (which could carry the disease) by 90%.
