Air Incheon, South Korea's only dedicated air cargo carrier, said Wednesday that it plans to provide regular flights to China, Japan and Russia in the coming weeks as part of its business expansion efforts. The airline company founded in 2012 currently offers irregular air cargo services from Incheon International Airport (IIA) and Russia's Sakhalin Island, using the two B737-400F cargo planes in its fleet. The company, which uses Incheon as its hub, said that starting Monday it will provide six weekly scheduled flights to Narita in Japan, followed by three regular flights per week to Yuzhno-Sakhalinsk, the largest city on Sakhalin Island, begining on April 30.
