Horizon Air

Horizon Air is a U.S. regional carrier that functions as the regional feeder operation for Alaska Airlines, so from a traveler’s point of view it operates short-haul, point-to-point and feed flights rather than long-haul services. The airline concentrates on routes in the Pacific Northwest and the U.S. West Coast, using smaller regional jets and turboprops to connect secondary airports to Alaska’s mainline network. As part of the Alaska Airlines group, its flights integrate with Alaska’s route and loyalty network (Alaska Airlines is a member of the Oneworld alliance), so bookings and benefits are commonly handled through Alaska rather than a separate Horizon system.

Frequent Flyer - Alaska Airlines' Mileage Plan

Horizon does not run its own frequent-flyer program; flights are credited to Alaska Airlines’ Mileage Plan when you choose to earn miles. Mileage earning and redemptions follow Alaska’s rules (miles accrual depends on fare class and Alaska’s earning charts), and Alaska’s elite tiers-MVP, MVP Gold, and MVP Gold 75K-apply to eligible travel and benefits. Because Horizon flights are integrated into Alaska’s network, Mileage Plan partners (including Alaska’s airline partners and oneworld members) are the main sources of additional redemption and earning opportunities, and for most travelers it makes sense to credit Horizon-operated flights to Mileage Plan.

Where Horizon Air Flies

From a traveler’s perspective Horizon is a U.S. regional airline focused on short-haul routes out of its Pacific Northwest bases such as Portland International (PDX) and Seattle-Tacoma International (SEA). It primarily serves intra-regional routes along the U.S. West Coast, the Pacific Northwest, interior West routes and short connections to Alaska and nearby Canadian destinations, feeding larger Alaska Airlines networks. Because Horizon operates as the regional arm of Alaska Airlines, its schedule extends via Alaska’s codeshares and partner connections rather than through a separate wide-reaching route map.

Aircraft and Cabin Classes

Horizon operates as a regional carrier with a typical regional-aircraft profile: its network is flown largely with smaller regional jets and, historically, turboprop types in the Dash 8 family. On the regional jets (commonly Embraer 175s) travelers will typically find a small front cabin marketed as First or First Class and a main economy cabin; turboprops are generally single-class or have more basic seating. Expect regional-seat configurations and fewer onboard amenities than mainline jets - Wi‑Fi, inflight entertainment screens, and galley service vary by aircraft and route.

Aircraft types operated: Fairchild F-27, Fokker F28 Fellowship, Embraer 175, BAC One-Eleven, Douglas DC-9-10, Fairchild Swearingen Metroliner, Dornier 328, de Havilland Canada DHC-8-100, de Havilland Canada DHC-8-200, de Havilland Canada DHC-8-400

Tips for Flying Horizon Air

• Credit Horizon-operated flights to Alaska Airlines’ Mileage Plan rather than expecting a separate Horizon program.
• Confirm at booking whether a flight is marketed by Alaska and operated by Horizon to know which aircraft and airport procedures apply.
• Expect limited carry-on and overhead space on some regional turboprops and smaller jets, so pack accordingly or check baggage rules in advance.
• Use the Alaska Airlines app or website to manage bookings, check in, and monitor seat assignments and connections on Horizon-operated flights.
