Delta Air Lines will add new nonstop flights between Seattle and both Hong Kong and Seoul Incheon from June 2014, as it optimises its service to the Asia-Pacific region from the city.
Daily Hong Kong flights operated on a 234-seat Airbus A330-200 will begin on 16 June 2014 and daily Seoul flights operated on a 210-seat Boeing 767-300ER will begin 2 June 2014, according to the Atlanta-based SkyTeam alliance member.
Delta will codeshare with its partner Alaska Airlines, which is based in Seattle, on the routes.
"By offering new service from Seattle to Seoul and Hong Kong, Delta will now offer customers service to the top five destinations in Asia," says Mike Medeiros, vice-president of Seattle at Delta, in a statement. "Our expanding Seattle network, combined with investments in our aircraft, the airport and the community shows our commitment to become Seattle's premier international carrier."
Asiana and Delta's SkyTeam partner Korean Air both operate Seattle-Seoul, Innovata schedules show. No carriers operate Seattle-Hong Kong.
The announcement comes a day after the carrier confirmed that it would end flights between Seattle and Osaka Kansai on 3 November. Delta cited an unstable revenue environment due to the devaluation of the Japanese yen and weak demand for the decision.
Delta did not immediately respond to questions about how the new routes would impact its existing Tokyo Narita-Hong Kong and Detroit-Seoul flights.
The airline operates 44 peak day departures to 18 destinations from Seattle.
