Alaska Airlines Expands Seattle Paine Field Flights With New San Jose Route and More West Coast Service

Alaska Airlines is expanding its presence at Seattle Paine Field, giving travellers across the Puget Sound region more options for West Coast journeys. The carrier plans to increase the number of seats available from Seattle/Everett by 50 percent, adding a new nonstop connection to San Jose, California, while also increasing capacity on several established routes.

The expansion is designed to make Paine Field a more useful alternative for passengers who live in Snohomish County, North Seattle and surrounding communities. Rather than travelling farther south to reach Seattle-Tacoma International Airport for every trip, more passengers will have access to Alaska Airlines flights closer to home, with additional frequencies planned on key West Coast markets.

When Will Alaska Airlines Launch the New San Jose Service?

The new nonstop route between Seattle Paine Field and San Jose is planned to begin in spring 2027, with Horizon Air scheduled to operate the service twice daily. Tickets are already available for purchase through Alaska Airlines, allowing travellers to plan journeys between the Puget Sound and Silicon Valley well ahead of the new service.

The twice-daily schedule is particularly relevant for business and leisure travellers who need greater flexibility during the day. San Jose provides access to Silicon Valley and the wider South Bay, while the connection also gives travellers another gateway into the broader San Francisco Bay Area.

How Is Los Angeles Service Changing From Paine Field?

Los Angeles is among the established routes receiving a significant boost as Alaska Airlines expands its Paine Field operation. Service is planned to increase to twice daily, with both flights operated using larger Alaska Airlines Boeing 737 aircraft.

The additional frequency and larger aircraft will increase the number of seats available between the Puget Sound and Southern California. For travellers, the changes can create more flexibility when planning short breaks, business trips and onward journeys through the Los Angeles area.

What More Flights Are Planned to Portland, San Diego and San Francisco?

Alaska Airlines is also increasing capacity on several other important West Coast routes from Paine Field. Portland service will grow to two daily flights, creating additional scheduling options for travellers moving between the Pacific Northwest markets.

The airline is also adding capacity to San Diego and San Francisco. These markets serve a mix of leisure and business demand, ranging from Southern California holidays and coastal getaways to trips connected with major business centres. More seats on these routes are expected to give passengers additional choice when selecting flights from Everett rather than travelling to a larger airport farther away.

Why Is Paine Field Important to Alaska Airlines?

The expansion reflects Alaska Airlines’ broader strategy for strengthening its Seattle-area network and maintaining a strong presence across the West Coast. Paine Field provides the airline with an additional airport option in the Puget Sound market and offers passengers a more convenient alternative depending on where they live.

Andrew Harrison, Alaska Airlines’ senior vice president and chief commercial officer, said Paine Field is an important part of the carrier’s Puget Sound network. He said the expansion would strengthen the airline’s regional presence through more seats, greater frequency and more convenient travel options for customers in Snohomish County, North Seattle and surrounding areas.

What Does the Expansion Mean for Puget Sound Travellers?

For passengers, the most immediate impact will be a broader choice of nonstop West Coast flights from Seattle Paine Field. The planned 50 percent increase in seats, combined with the new San Jose service and additional capacity to Los Angeles, Portland, San Diego and San Francisco, gives travellers more opportunities to select Paine Field for regional journeys.

The changes also strengthen Paine Field’s role within the Puget Sound aviation network. As Alaska Airlines increases frequencies and aircraft capacity, the airport could become increasingly useful for travellers seeking convenient access to major West Coast destinations without starting every journey at Seattle-Tacoma International Airport.

A Larger West Coast Footprint From Everett

Alaska Airlines’ planned growth at Paine Field marks a substantial expansion of its Seattle/Everett operation. The combination of a new twice-daily San Jose route, additional Los Angeles service, two daily Portland flights and added capacity to San Diego and San Francisco will give the airport a stronger portfolio of West Coast connections.

With the San Jose service scheduled for spring 2027 and other capacity increases beginning from this fall, the changes will progressively expand the choices available to Puget Sound travellers. For Alaska Airlines, the move reinforces Paine Field as an important component of its wider Seattle network and West Coast strategy.
