ACI steps up to the plate, demanding global harmonisation of standards and processes At least Airports Council International (ACI) World Director-General Luis Felipe de Oliveira made some salient points, on another panel (‘Restoring Cross-Border Mobility’), when he said that cooperation on global standards towards a global harmonisation of processes would help promote industry recovery from the COVID-19 crisis (even if he did choose clichés such as “seeing the light at the end of the tunnel” to express it). Mr de Oliveira said there were some signs for optimism, but that the industry is “braced for” 1H2021 as the situation will "get worse before it gets better this year". ACI expects to see "light at the end of the tunnel with the development of vaccines and by using tests to reduce quarantines" around Jun/Jul-2021.
