The International Air Transport Association (IATA) has published Biosecurity for Air Transport: A Roadmap for Restarting Aviation, which outlines its proposal for a “layering” of temporary biosecurity measures. The roadmap, said the association, aims to provide the confidence that governments will need to enable the reopening of borders to passenger travel, and the confidence that travelers will need to return to flying. Alexandre de Juniac, CEO, said there is no single measure that will reduce risk and enable a safe re-start of flying. But he said that layering measures “that are globally implemented and mutually recognized by governments can achieve the needed outcome.” Highlights of the roadmap include: pre-flight (temperature screening, physical distancing, face coverings, sanitization); in-flight (face coverings, simplified catering, no lining up for restrooms); and arrival (temperature screening, automated customs and border control, accelerated processing and baggage claim). IATA said these and other measures should be temporary, regularly reviewed and replaced when more efficient options are identified or removed if they become unnecessary.
