Korean Air has launched a regular cargo flight between southwest China's city of Chengdu and Seoul, airport authorities confirmed Saturday.

The Seoul-Chengdu-Singapore-Seoul cargo flight will arrive at the Chengdu Shuangliu International Airport at about 2:10 a.m. every Wednesday and arrive in Seoul at about 6:10 p.m. local time, an airport spokesman said.

A Boeing 747-400F cargo plane with a capacity of 100 metric tons will be used for the flight, he said.

"The new air route will allow international cargo dispatched from Chengdu to reach destinations around the world much faster than before," he said.

The first cargo flight took place on July 20, he said.
