Alaska Airlines is in the middle of its biggest expansion yet, and the schedule through mid-2027 shows it. According to aviation data firm Cirium, the carrier has ten new nonstop routes lined up, starting this November and running through June 2027 — a mix of handy regional hops and, for the first time, a serious long-haul push out of Seattle.

The first additions arrive in November 2026, when daily Embraer E175 flights begin connecting Santa Rosa's Sonoma County Airport with both Phoenix and Boise. Those seasonal services run until mid-April — a neat option for wine country locals chasing snow or desert sun. In December, the network stretches to Hawaii: new Boeing 737 flights from Boise and Spokane to Honolulu, running daily until mid-March from Boise and through late April from Spokane.

Then comes the headline news. From May 2027, Seattle-Tacoma becomes Alaska's long-haul launchpad. Two European routes start that month using the airline's Boeing 787-9 Dreamliners: Seattle to Paris Charles de Gaulle, peaking at five flights a week over summer, and Seattle to Athens, running three times weekly. On the Asia-Pacific side, Alaska will use inherited Hawaiian Airlines Airbus A330-200s to fly from Seattle to Osaka's Kansai Airport four times a week from mid-May, and from June three times a week to Papeete in Tahiti — a proper South Pacific link from the Pacific Northwest.

Two domestic routes round out the plan. In February and March 2027, SkyWest-operated E175s will fly twice weekly between Portland, Oregon and Yampa Valley in Colorado — prime ski country — and from mid-April a new Seattle Paine Field to San Jose link runs twice daily with Horizon Air E175s.

For travellers, this matters on a few levels. West Coast flyers outside the big hubs — Boise, Spokane, Santa Rosa — get direct access to Honolulu without a connection, and Yampa Valley gains a Portland option for ski season. Bigger still: Seattle is quietly becoming one of North America's best one-stop gateways to Europe and the Pacific. Flying nonstop to Athens or Paris from Seattle, or reaching Tahiti and Osaka on Hawaiian's widebody jets under the Alaska banner, opens up itineraries that previously meant transiting Los Angeles, San Francisco or a East Coast hub. Prices on newly launched routes are often competitive early on, and booking the first summer of a new widebody service tends to be where the value is.

If you're plotting a 2027 trip, keep an eye on when the Athens and Paris routes load into the booking system — May departures line up nicely with shoulder-season Europe, and the Osaka flights pair well with Japan's late spring. And with Hawaiian now part of the same group, expect the Honolulu connections from Spokane and Boise to feed nicely into Hawaiian's island-hopping network.
