Tokyo and Seoul are just a start for Alaska.
The airline teased plans for at least 12 new intercontinental routes from Seattle in the future.
Alaska is also adjusting the two airlines schedules between Hawaii and the U.S. mainland to offer travelers more options.
Hawaiian will also fly its largest planes between Seattle and Anchorage next summer.
And Alaska plans new nonstops between San Francisco and both Kona and Lihue in Hawaii beginning in June.
The changes are all part of the synergies that Alaska hopes to gain by merging with Hawaiian.
