"We don’t see any alternative solution that would be less challenging or more effective," IATA Director General Alexandre de Juniac said.
Airlines hammered by the pandemic are pressing governments to embrace alternatives to blanket travel restrictions that are still hampering a traffic recovery - and now tightening again in Europe amid resurgent case numbers.
With rapid antigen tests becoming available for as little as $7 each, De Juniac said, airlines will push for their use to be endorsed by International Civil Aviation Organisation (ICAO), the UN agency that oversees global aviation rules.
IATA believes production could be quickly increased to millions per day and the tests phased in between late October and the end of the year, "helping to save a part of the winter season", De Juniac told Reuters television.
A global agreement is needed to ensure pre-departure test results are uniformly accepted by the destination country, he said. "It will also boost passenger confidence that everybody on the aircraft has been tested."
Antigen tests are faster but generally more likely to miss positive cases of the virus than laboratory-based molecular diagnostic tests.
Among companies marketing the new tests, German diagnostics specialist Qiagen said earlier this month it planned to launch a Covid-19 antigen test that provided results in 15 minutes and could be deployed in airports or stadiums.
