Horizon Air is the sister-carrier to Alaska Airlines. It is also a codeshare partner of Northwest Airlines, American Airlines, and Delta Airlines. Baggage limitations on Horizon Air flights are the same as Alaska Airlines.
Please note that on Horizon Air flights with smaller airplanes (Bombardier Q400 or CRJ aircraft), larger carry-on items may need to be "gate-checked" when getting onto the plane.
