Alaska Airlines Plans 50% Seating Capacity Expansion at Paine Field Through 2027

The San Jose route is scheduled to begin April 14, 2027, with two daily flights operated by Horizon Air on 76-seat Embraer E175 aircraft.
The switch to Boeing 737s on Los Angeles flights represents at least a 63% increase in seats per flight compared with the smaller E175s; Alaska’s San Diego service is scheduled to switch to a 737 on Nov. 1.
Alaska is currently the only airline serving Paine Field; Frontier operated there briefly in 2025, while United served the airport from 2019 through 2021.
Paine Field operator Propeller Airports CEO Brett Smith said the expansion responds to strong demand for convenient service and highlighted the terminal’s valet parking, streamlined security and lounge-like setting.
