The International Air Transport Association (IATA) said its latest analysis showed that annual passenger revenues will fall by $252 billion if severe travel restrictions remain in place for 3 months.
That would mark a 44% drop compared to 2019 revenues, and is more than double the $113-billion drop previously predicted by IATA before countries around the world began introducing sweeping travel restrictions.
"It is the deepest crisis we ever had in our industry," IATA chief Alexandre de Juniac told reporters in a virtual briefing, calling on governments to quickly step up and provide desperately needed liquidity.
"Airlines are fighting for survival in every corner of the world," he said in a statement, pointing out that "travel restrictions and evaporating demand mean that, aside from cargo, there is almost no passenger business."
"For airlines, it's apocalypse now. And there is a small and shrinking window for governments to provide a lifeline of financial support to prevent a liquidity crisis from shuttering the industry."
On Tuesday, it said that while some governments were stepping up, it was still far from enough to cover the needs.
"We need money," Juniac told reporters.
He stressed that IATA fully supported government measures to slow the spread of COVID-19, which has now infected nearly 400,000 people worldwide and killed close to 17,000, according to an Agence France-Presse tally based on official data.
"But we need them to understand that without urgent relief, many airlines will not be around to lead the recovery stage," he said.
