ATR 42-600 Horizon 'Meatball' Livery

Horizon Air Industries, Inc., operating as Horizon Air, is an American regional airline based in SeaTac, Washington, United States. Horizon Air and its sister carrier Alaska Airlines are subsidiaries of Alaska Air Group, and all Horizon-operated scheduled flights are marketed and sold by Alaska Airlines. Planes operated by Horizon are co-branded as Alaska Horizon in order to differentiate Horizon's planes from those operated by Alaska's other regional airline partner, SkyWest Airlines. Horizon Air started operations in September 1981, was purchased by the Alaska Air Group in November 1986, and continued to fly as a separately branded airline until 2011, when it shifted to the current capacity purchase agreement business model.
