Alaska Airlines has begun the first commercial service out of Paine Field-Snohomish County Airport in Everett, Wash. By mid-March, the carrier will have its full flight schedule of 18 daily nonstop departures to eight West Coast cities in place. All Alaska flights at Paine Field are operated by Horizon Air with Embraer 175 aircraft, which feature a three-class cabin, including first class and premium class. Every seat on the plane is either a window or an aisle – there are no middle seats. From Paine Field, guests can fly to eight West Coast cities: Las Vegas; Los Angeles; Orange County, Calif.; Phoenix; Portland, Ore.; San Diego; San Francisco; and San Jose, Calif. From Alaska's gateway airports – such as Los Angeles or San Francisco – guests can then connect with the carrier‘s global partners to fly to cities around the globe. Flyers can also earn and redeem miles with Alaska's Mileage Plan program.
