Global airline traffic recovered to 68.5% of pre-pandemic levels last year and surged 64.4% from 2021, according to figures published by global aviation body IATA on Monday.

Airlines lost tens of billions of dollars in 2020 and 2021 due to the COVID-19 pandemic and saw the first signs of relief as travel started to return in 2022, particularly during the summer months.

With China’s recent reopening, that recovery is set to go on, the head of IATA said.

“This momentum is expected to continue in the new year, despite some governments’ overreactions to China’s reopening,” said Willie Walsh, IATA’s director-general.

China previously said it would resume overseas group tours organized by tour agencies and online travel companies for Chinese citizens starting from Monday.

European carriers saw full-year traffic jump 132.2% compared to 2021, while North American airlines saw a 130.2% rise year-on-year, according to the data.

But analysts and executives have long said that recovery to full pre-pandemic levels depends on how quickly travel to and from China can bounce back.

“It is vital that governments learn the lesson that travel restrictions and border closures have little positive impact in terms of slowing the spread of infectious diseases in our globally inter-connected world,” Walsh added.

Many countries, like France, introduced mandatory COVID testing for those flying from China, sparking protests from the aviation sector.
