The impact of the coronavirus disease (COVID-19) pandemic on global air transport is without precedent. Airports have seen a -28.4 per cent decline in global passenger traffic volumes for the first quarter of 2020, equivalent to a reduction of 612 million passengers in absolute terms. These volumes (domestic and international traffic) are expected to decrease by -50.4 per cent for 2020 as a whole as compared to 2019 figures1 . ICAO estimates that by the end of 2020, the COVID-19 impact on scheduled international passenger traffic could reach reductions of up to 71 per cent of seat capacity and up to 1.5 billion passengers globally2 . Airlines and airports face a potential loss of revenue of up to USD 314 billion3 and USD 100 billion respectively, for 2020.
