Southwest Airlines announced they’ll be launching new service to Everett’s Paine Field, located about 30 miles north of downtown Seattle and 40 miles north of Seattle-Tacoma International Airport, which Southwest currently serves.
Routes haven’t announced yet, but I’d expect service to be to/from Los Angeles, Oakland, and/or Las Vegas based on their current route network.
Per the Seattle Times,
Southwest Airlines will be the third passenger airline to fly out of Paine Field in Everett, boosting the planned number of total daily departures to 24 flights.
The Dallas-based carrier said it will operate five flights daily after the new terminal opens in September. It will fly Boeing 737s, larger than the Embraer E175 regional jets that Alaska Airlines and United plan to operate initially.
