Delta Cuts Hong Kong Service From Seattle, in Favor of Osaka

Delta Airlines today announced the company will be cutting it's Seattle to Hong Kong route, replacing it with a new Seattle to Osaka, Japan route.
Delta's Hong Kong service will be effectively cut from October 4. And the resumed service to Osaka will start during 2019, no exact date has been set as of yet. Timing of the flights were not released either.
Delta's fleet of Boeing 767-300 aircraft will be tasked with flying to Osaka. These 767 aircraft feature 225 seats in total, which include: 25 flat-bed seats, 29 premium economy seats and 171 economy seats.
With this announcement, it may seem Delta is withdrawing themselves completely from the Seattle to Hong Kong market. However, Delta will still be able to give passengers the ability to fly between Seattle and Hong Kong, via Seoul. With the Seoul to Hong Kong portion of the trip operated by Joint Venture partner, Korean Airlines.
This will be a reversal of what Delta Airlines did back in 2013 and 2014. In 2013, Delta axed services to Osaka, while services to Hong Kong began in 2014.
In 2013, Delta is quoted of saying that an "unstable revenue environment caused by Japanese yen devaluation and weak demand" was a leading cause to why Osaka flights were cut.
Over the four years Delta has served Hong Kong from Seattle, the company's Boeing 777-200 and Airbus A330-200 have been tasked with the mission.
This will become Delta's second flight to Osaka, and first flight direct from the mainland United States. The airline also serves Osaka from Honolulu, Hawaii.
From Seattle, Delta flies to four other destinations in Asia. These include: Shanghai and Beijing, China, Seoul, South Korea, and Tokyo, Japan.
