Alaska Airlines Expands from Santa Rosa, Resumes Seattle-Long Beach Route

‍SEATTLE — Alaska Airlines (AS) announced on May 7 the addition of four new nonstop routes from Charles M. Schulz-Sonoma County Airport (STS) and Long Beach Municipal Airport (LGB), continuing the carrier's expansion across California.

Alaska will return to Long Beach after a decade-long absence, launching twice-daily year-round service to Seattle-Tacoma International Airport (SEA) beginning September 8, operated on Boeing 737 aircraft. The addition makes Alaska the only airline serving Seattle from all five major airports in the Los Angeles Basin.

Santa Rosa expansion

Three new seasonal routes from Santa Rosa will begin on November 1, all operated on Embraer E175 regional jets. Service to Phoenix Sky Harbor International Airport (PHX) will run daily through April 21, 2027, while flights to Salt Lake City International Airport (SLC) and Boise Airport (BOI) will operate daily through the same period, bringing Santa Rosa's total nonstop destinations to 12.

Alaska has served Charles M. Schulz-Sonoma County Airport (STS) for nearly two decades and remains the largest carrier there. The Salt Lake City and Boise routes are currently unserved markets from the North Bay, timed to connect wine country travelers to ski destinations ahead of the winter season. Alaska's Wine Flies Free program allows Atmos Rewards members to check an entire case of wine, up to 12 bottles, at no charge.

Connectivity

All three Santa Rosa routes will be operated by Alaska's regional fleet, which the carrier says is the only regional fleet in the world fully equipped with Starlink Wi-Fi, offering gate-to-gate connectivity through a T-Mobile partnership at no cost to Atmos Rewards members. 

Starlink is scheduled to roll out across Alaska's mainline fleet, which will serve Long Beach, throughout 2026.
