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) downgraded its 2020 traffic forecasts, after "a dismal end to the summer travel season".
The association, which represents 290 airlines, says it expects traffic to be 66% below the level it was in 2019.
The IATA estimates that it will be at least 2024 before air traffic reaches pre-pandemic levels.
A second surge in Covid-19 cases and more government restrictions meant the sector has not seen a strong rebound.
The travel industry saw a precipitous drop in business after the coronavirus developed into a pandemic, BBC reported.
Through the year major airlines, airports and tour firms have collectively announced thousands of job losses.
