"This is the worst year in aviation history and airlines are in survival mode. The carriers in Asia-Pacific will experience the largest losses at $29 billion. That's a loss of $30.09 per passenger," Conrad Clifford, IATA's Regional Vice President for Asia Pacific, said.
"It will take a few years for the industry to get back to 2019 levels of activity," said Clifford.
