Alaska Airlines has unveiled plans to launch 13 new nonstop routes beginning next spring, marking a major step in the carrier’s ongoing expansion across its key hubs in San Diego and Portland. Alongside these additions, the airline will introduce two new destinations, deepen its commitment to Hawai‘i with more flights, and further establish its position as the leading carrier at Santa Rosa-Sonoma Airport.
The new nonstop routes will bring Alaska Air Group’s total network to 142 destinations in 2026, the largest in the airline’s history. As part of the new rollout, the carrier will begin daily service between San Diego and Tulsa, and from Seattle to both Tulsa, Oklahoma (TUL), and Arcata-Eureka, California (ACV), located along the scenic California Redwood Coast. With the addition of Arcata-Eureka, Alaska Airlines will now serve more California airports year-round than any other U.S. airline, strengthening its footprint in the state.
“With bold expansion in San Diego and Portland, plus more flights to Hawai‘i and new destinations like Tulsa and Arcata-Eureka, Alaska is redefining what it means to connect guests to a remarkable travel experience rooted in safety, care and performance,” said Kirsten Amrine, vice president of revenue management and network planning at Alaska Airlines.
San Diego remains a central focus for Alaska Airlines’ growth strategy. The carrier, which already operates the most nonstop destinations from San Diego of any airline, plans to increase its operations from the Southern California hub by more than 35% in spring 2026 compared to the same season in 2025. The new nonstop routes will include Dallas-Fort Worth, Oakland, Raleigh-Durham, Santa Barbara and Tulsa. With these additions, Alaska and Hawaiian Airlines will together serve the 15 most popular markets from San Diego, operating 49 nonstop destinations.
In Portland, the airline continues to build momentum following a successful summer season. Alaska will begin new services in May from Portland to Baltimore, Idaho Falls, Philadelphia and St. Louis, expanding its nonstop network from the Rose City to 62 destinations. The airline will also introduce a second daily flight to Newark, make its Portland–Līhu‘e (Kaua‘i) connection year-round, and increase daily flights to Santa Rosa-Sonoma to three.
The carrier’s commitment to Hawai‘i also remains strong, as it continues to serve more airports between California and the islands than any other airline. A new seasonal route will debut next summer between Honolulu and Hollywood Burbank Airport, reconnecting the two airports for the first time in over 20 years. Starting in the spring, service between Los Angeles and Kahului (Maui) will expand to two daily nonstops with an additional seasonal frequency. In June, flights between San Francisco and both Kona (Hawai‘i Island) and Līhu‘e (Kaua‘i) will increase to daily service. By early summer, Alaska Airlines will offer daily flights to all four Hawaiian Islands from San Francisco, matching the level of connectivity it already provides from Los Angeles, Portland, San Diego and Seattle.
At Santa Rosa-Sonoma, Alaska is serving twice as many destinations as any other airline. The company is introducing additional flights to Portland and San Diego, along with a new intra-California route connecting Santa Rosa-Sonoma and Ontario, located east of Los Angeles. This brings Alaska’s network from Santa Rosa-Sonoma to six California cities, including a new seasonal route to Palm Springs that will launch on October 26.
