Alaska will expand service from Seattle/Everett to key West Coast destinations, including twice-daily Los Angeles (LAX) flights on larger Boeing 737 aircraft, two daily Portland (PDX) flights and more seats to San Diego (SAN) and San Francisco (SFO).
Puget Sound area travelers will have more ways to fly from Seattle Paine Field (PAE) next summer, with Alaska Airlines planning a major expansion that will bring more flights, more seats and more convenient access to the West Coast.
The growth is part of Alaska’s broader strategy to strengthen its Seattle-area network, giving guests more convenient access across the Puget Sound region while reinforcing the airline’s position as the West Coast’s leading carrier.
The new San Jose route is planned to begin in Spring 2027 and operate twice daily on Horizon Air, making it easier for guests to reach the South Bay and Bay Area.
Guests will also see more choices on several familiar West Coast routes. Los Angeles will grow to twice-daily service, with both flights operated on larger Alaska Boeing 737 aircraft. Portland will grow to two daily flights, offering more flexibility for quick trips across the Pacific Northwest and beyond. Alaska will also add capacity in San Diego and San Francisco, giving guests more seats to sunny escapes, business centers and favorite West Coast destinations.
Paine Field is an important part of our Puget Sound network, giving guests a simpler, more convenient way to access Alaska’s West Coast flying. 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,” says Andrew Harrison, Executive Vice President and Chief Commercial Officer, Alaska Airlines.
