Air Seoul, a South Korean low-cost carrier, announced on Sept. 11 that it will suspend flight services linking Incheon and Shizuoka starting from Sept. 30 as the number of passengers is on the decline due to deteriorating ties between Tokyo and Seoul. It will also reduce the number of flights between Incheon and both Kansai International Airport and Yonago starting from Sept. 16. (Abridged)
