Alaska Airlines and Hawaiian Airlines have announced new seasonal flights to and from Hawaii, expanding domestic travel options while making a major change to their Pacific network.

Beginning in mid-December, Alaska Airlines will launch new nonstop seasonal service between Honolulu and Boise, Idaho, and Honolulu and Spokane, Washington. Alaska says it will be the only airline offering direct flights on both routes.

The airlines will also add three weekly seasonal flights between Honolulu and Las Vegas during peak holiday and spring break travel periods.

However, Hawaiian Airlines will discontinue its seasonal Honolulu–Auckland route. The airline cited high fuel costs, slower-than-expected demand recovery, unfavorable exchange rates and changing travel trends as reasons for the decision.

The additional domestic flights are expected to increase seasonal Hawaii capacity by 3% year over year, rising to as much as 6% during peak holiday periods.

More U.S. connections to Hawaii — but one Pacific route is saying aloha for now.
