Taiwan's Mandarin Airlines has started a new service between Kaohsiung and Xiamen.
The China Airlines (CAL) subsidiary will operate on the route once a week with Airbus A330 aircraft, says CAL.
"The new service between Kaohsiung and Xiamen will make cross-strait travel more convenient for residents of southern Taiwan and expand the range of destinations accessible from Kaohsiung," it adds.
Mandarin will compete on the route against Taiwan's TransAsia Airways, which operates between Kaohsiung and Xiamen once a week, according to schedules in Innovata.
CAL and Mandarin operate 61 flights across the Taiwan Strait every week, serving 14 major destinations in mainland China.
CAL also plans to increase services to Beijing, Guangzhou and Shenzhen, after Taiwanese and Chinese authorities agreed recently to increase cross-strait flights.
