The airport saw a daily average passenger flow of more than 130,000 people from March 1 to March 21, with the number exceeding 150,000 on March 19, a pre-pandemic peak level, the authorities noted.

In the new flight season to start on Sunday, the airport plans to increase weekly flight numbers to over 7,300, up nearly 3 percentage points compared to the same season last year.

China's civil aviation sector has continued to show signs of recovery.
