HAGATNA, Guam (AP) ― United Airlines has launched daily direct flights between South Korea and Guam for the first time, serving a market that helped boost Guam’s tourism industry when the number of visitors from Japan declined.

“As Guam’s hometown airline, we are delighted to bring additional economic benefits to our tourism industry and further expand the extensive route network from our Guam hub,” said Sam Shinohara, United’s managing director for business development in the Asia-Pacific.

United also is launching twice-weekly direct flights between Guam and Shanghai, the Pacific Daily News reported Tuesday.

Japan was Guam’s top source of visitors for decades, but experts say the number of travelers from Japan is declining because of the country’s aging population and the weakened value of the yen against the U.S. dollar. Guam’s tourism industry has been working on improving its secondary visitor markets.
