Hundreds of thousands of aviation jobs are at risk without more state aid, a global industry body has warned.
The International Air Transport Association (IATA) has lowered its traffic forecasts for 2020 after a “dark end to the summer travel season”.
The association, which represents 290 airlines, says it expects traffic to be 66% below 2019 levels.
IATA estimates it will be at least 2024 before air traffic reaches pre-pandemic levels
A second jump in the Covid-19 cases and more government restrictions mean the sector has not seen a strong recovery.
The tourism industry saw a sharp decline in business after the coronavirus became a pandemic.
During the year, major airlines, airports and travel companies collectively reported thousands of job losses.
“In the absence of additional government measures to ease and reopen borders, hundreds of thousands of airline jobs will disappear,” said IATA CEO Alexander de Juniac.
He called for routine testing of Covid-19 passengers before departure to increase consumer confidence in air transport and make governments more willing to open borders.
Airlines have already shown signs of struggle this year.

Last month, the world’s largest airline, American Airlines, said it would cut 19,000 jobs in October when the government’s wage support scheme ended. Redundant jobs make up 30% of its pre-pandemic workforce.
Earlier this year, United Airlines said up to 36,000 jobs were at risk. Germany’s Lufthansa has warned it could cut 22,000 positions, and British Airways has said it is cutting 13,000 jobs.
