Hawaiian Airlines will add three new weekly flights between Honolulu and Sea-Tac Airport starting in January.
The airline now operates just one direct flight from Seattle to Honolulu every day, as well as one daily flight from Seattle to Kahului.
The airline is also increasing flights to and from Las Vegas and Los Angeles.
The new flights starting Jan. 7 to and from Seattle will utilize the new narrow-body, fuel-efficient Airbus A321neo. Current flights are on the Airbus 330. The Airbus321 is a short to medium-range twin-jet airliner. The 330 is a medium-to-long wide-body plane.
Sea-Tac is the eighth-busiest airport in the country and is quickly reaching capacity. Sea-Tac served nearly 50 million passengers last year, and airport officials say they anticipate 66 million in the next 15 years.
Earlier this year, three airlines – Japan Airlines, Cathay Pacific and Delta – announced new nonstop flights from Sea-Tac to Asia.
