Alaska Airlines adds 10 nonstop routes, four long-haul from Seattle

Alaska Airlines will open ten new nonstop routes between November 2026 and June 2027, according to aviation analytics firm Cirium. The batch mixes daily regional hops in the American West with four long-haul international corridors out of Seattle-Tacoma, the carrier's first new European point in some time.

The winter routes

Two routes begin in November 2026, both aimed at Charles M. Schulz Sonoma County Airport in Santa Rosa, California. They originate at Phoenix Sky Harbor and Boise. The daily regional flights run until mid-April, flown on Embraer E175 jets supplied by Horizon Air and SkyWest under the Alaska brand.

December then brings two links to Daniel K. Inouye International Airport in Honolulu, departing Boise and Spokane on mainline Boeing 737 aircraft. Boise flights run daily until mid-March, while Spokane service lasts until late April. Both feed Alaska's long-established Hawaii network following its Hawaiian Airlines acquisition.

Kirsten Amrine, Alaska's vice president of network planning and revenue management, framed the winter additions around escape. "Whether you're in Santa Rosa looking for a winter escape to the snow or sun, or a SoCal traveler looking for a convenient alternative to the region's busiest airports, this expansion has you covered."

The long-haul expansion

The headline 2027 work is four long-haul corridors from Seattle-Tacoma International Airport. Two cross the Atlantic to Europe aboard Alaska's 787-9 Dreamliner widebodies. The other two reach the Asia-Pacific using Airbus A330-200s inherited from Hawaiian, which Alaska folded into its operation.

Paris Charles de Gaulle and Athens Eleftherios Venizelos both launch in May 2027. Seattle to Paris peaks over the summer at five flights a week, while Athens starts at three weekly. The pair mark Alaska's expansion beyond its long-standing European reliance on a handful of seasonal gateways.

On the Pacific side, Osaka's Kansai International begins in mid-May, operated four times weekly with Hawaiian's A330-200s. In June the same jets open a route from Seattle to Papeete in Tahiti, running three times a week. Papeete gives Alaska a rare South Pacific outpost.

Once all four launch, Alaska will operate nine long-haul routes from Seattle in 2027, Cirium's data show. The city has become the airline's anchor for international flying since the Hawaiian merger, concentrating widebody capacity there while domestic traffic keeps feeding connections from across the Northwest.

The domestic additions

Domestic flying still dominates Alaska's flying: Cirium counts 50,764 domestic flights in July 2027 against 1,481 international. The first links Portland International in Oregon with Yampa Valley Regional in Colorado, twice weekly in February and March.

That Colorado service runs on SkyWest E175 regional jets, suggesting a seasonal ski-market play given Yampa Valley's position as the airport serving Steamboat Springs. Twice-weekly frequency is thin, aimed at weekend travellers rather than daily business traffic.

The remaining domestic addition comes mid-April 2027, linking Seattle Paine Field in Washington with San Jose Mineta in California. It runs twice a day on Horizon Air E175s. Paine Field is Seattle's secondary airport, and the route hands Silicon Valley commuters an alternative to the larger Sea-Tac.

The ten routes span small regional airports and flag-carrier hubs alike. Santa Rosa, Boise, Spokane, Portland, Paine Field and Yampa Valley are on the domestic side, served by E175 or 737 metal. The international work concentrates on Alaska's widebodies and Hawaiian's Airbus fleet at a single hub.

Alaska, a member of the oneworld alliance, has pushed growth in recent years through its long-haul debut and the Hawaiian acquisition. Its route map now reaches Europe, the Asia-Pacific and the South Pacific from Seattle, extending a network long built on domestic strength across the western United States.

The schedule is staggered deliberately. Two routes open in November, two in December, then six across 2027 stretching to June. That sequencing spreads aircraft and crew commitments and lets each market launch before summer peaks, rather than concentrating new capacity in a single season.

Frequencies vary widely by corridor. Sonoma County runs daily on regional jets, Paris rises to five a week, Osaka to four, while Athens and Papeete hold at three. U.S. domestic routes open at four and fourteen weekly. The mix reflects demand Alaska measured before committing each market.

The winter routes terminate on a seasonal cadence rather than year-round: Santa Rosa service ends mid-April, Boise to Honolulu mid-March, Spokane to Honolulu late April. Alaska has not said whether any of the four long-haul corridors will run year-round or pause after their first summer.

For travellers, the additions open direct options that previously demanded connections. Sonoma County to Phoenix and Boise removes a hop through San Francisco; Seattle to Papeete removes a connection through Los Angeles or Auckland. Athens is a gateway Alaska had never served directly.

Alaska has not disclosed fares for any of the ten routes. What is fixed is timing: Santa Rosa and Honolulu flights in November and December this year, then Paris, Athens, Osaka and Tahiti from May and June 2027, with the Portland and Paine Field domestic links filling the winter and spring between.
