HAIKOU - Hainan Airlines plans to resume all domestic flights into and out of Hainan, southern China's tourist island, starting Sunday, according to the company.

The airline said it is expected to offer nearly 500 flights on more than 110 air routes each week.

The resumption of domestic air services is expected to bring more tourists to the tropical island as it helps connect Hainan with 39 big and medium-sized cities across the country.

The airline has launched charter flight services for government and enterprise customers since Feb 19 to fully support work and production resumption all over the country.
