• AFTER rebounding to pre-pandemic levels last year, air traffic in China has sunk back down to 35 per cent of what it was in 2019 as officials continue to impose restrictions on travel as part of their fraught battle with Covid-19
• Flight activity has dropped sharply in the past two months, coinciding with a rise in infections and as authorities turn to more targeted measures instead of broad steps like citywide lockdowns.
