In short: What began in 1981 as a small fleet of three aircraft serving Washington state has evolved into a vital component of the Alaska Air Group. From early hijacking scares to a complete shift in business models, the history of Horizon Air is a study in regional aviation evolution.

Milt Kuolt, Joe Clark, and Bruce McCaw established Horizon Air in May 1981, originally intending to operate routes to Hawaii before refocusing on Washington. The airline began operations on September 1, 1981, using three Fairchild F-27 aircraft. Its early years were marked by aggressive expansion through acquisitions, such as Air Oregon in 1982 and Transwestern Airlines of Utah in 1983, often to mitigate significant monthly operating deficits.

A pivotal shift occurred in November 1986 when Alaska Air Group purchased the carrier. For decades, Horizon operated as a separately branded airline, even entering codeshare agreements with United Airlines and Northwest Airlines. However, on January 1, 2011, the company transitioned to a capacity purchase agreement (CPA) model. Under this arrangement, Alaska Airlines handles scheduling, marketing, and pricing, while Horizon focuses on operating and maintaining the fleet. This change also saw the retirement of the standalone Horizon brand in favor of the co-branded 'Alaska Horizon' livery.

The airline's history includes notable turbulence, both operational and literal. In 2017, a severe pilot shortage forced the cancellation of hundreds of flights. The carrier has also faced high-profile incidents, including the 2018 theft of a Bombardier Q400 by a ground service agent and a 2023 incident where an off-duty pilot attempted to activate engine fire extinguishers mid-flight. Today, headquartered in SeaTac, Washington, the airline serves 45 destinations across the western United States and Canada, utilizing aircraft like the Embraer 175 and the Bombardier Q400.
