Hawaiian Airlines will begin nonstop service to Seoul, South Korea starting January 2011, the carrier announced today.

The airline will fly to the destination four times a week — Tuesdays, Thursdays, Saturdays and Sundays.

The new route will be the airline’s sixth international destination.

Hawaiian, the state’s largest interisland air carrier, currently serves Sydney, Australia; Manila; Pago Pago, American Samoa; Papeete, Tahiti; and has tentative approval to begin service to Tokyo’s Haneda International Airport in October.
