Alaska Airlines is set to significantly enhance its Seattle-area network by expanding services at Seattle-Everett Paine Field. Starting this autumn, the airline will increase seat capacity by 50%, with the expansion continuing through to the summer of 2027. This move will introduce new nonstop routes and bolster existing services to key West Coast destinations.

The airline plans to launch a new nonstop service between Seattle-Everett and San Jose, California, beginning in spring 2027. This route will operate twice daily on Horizon Air, providing a vital link between the north Puget Sound region and the South Bay area. Additionally, Alaska Airlines will expand its service to Los Angeles, increasing to twice-daily flights using larger Boeing 737 aircraft. Portland will also see an increase to two daily flights, whilst additional capacity will be added to routes serving San Diego and San Francisco.

Andrew Harrison, senior vice president and chief commercial officer at Alaska Airlines, stated, "As we grow, we're strengthening our presence across the region with more seats, more frequency, and more convenient travel options for guests in Snohomish County, North Seattle, and beyond."

Brett Smith, CEO of Propeller Airports, expressed enthusiasm for the expansion, noting the strong demand for more convenient air service from Paine Field. "These added flights give travellers more nonstop options close to home and further strengthen Paine Field's role in serving the region," he said.

This expansion is part of Alaska Airlines' broader strategy to reinforce its position as the leading carrier on the West Coast, offering more convenient access to popular destinations and enhancing its Seattle hub.
