Horizon Air is a US regional airline founded in 1981 and based in the Pacific Northwest, operating as a wholly owned subsidiary of Alaska Air Group under a capacity purchase agreement. Since 2011, Horizon-operated flights have been marketed, sold, and branded entirely as Alaska Airlines — you’ll always book, check in, and fly as an Alaska Airlines passenger, even though Horizon’s own crews and aircraft (a fleet of Embraer 175 regional jets) operate the flight.

Horizon Air Route Network
Horizon Air operates regional routes throughout the Pacific Northwest, the Western US, and into Canada, feeding passengers into Alaska Airlines’ broader network from smaller cities that don’t support mainline jet service.
Primary Hub
Seattle-Tacoma International Airport (SEA) & Portland International Airport (PDX)
Horizon Air’s operations are centered on Seattle-Tacoma International Airport (SEA) and Portland International Airport (PDX), both major Alaska Airlines hubs.
Alliance & Partner Airlines
As part of Alaska Air Group, Horizon Air flights are booked entirely through Alaska Airlines and benefit from Alaska’s oneworld alliance membership and Mileage Plan program — there’s no separate Horizon Air booking channel or loyalty program.
Baggage, Seating & Onboard Amenities
A quick reference before you pack — always confirm exact allowances on your fare rules at booking, since they vary by route and cabin.
Carry-On & Personal Item
Since Horizon flights are sold and ticketed as Alaska Airlines, standard Alaska Airlines carry-on rules apply: one carry-on bag plus a personal item on most fares.
Checked Baggage
Checked baggage allowance follows standard Alaska Airlines fare rules, since Horizon-operated flights are ticketed under the Alaska Airlines brand.
Excess Baggage Fees
Overweight, oversized, or extra bags typically incur a per-bag fee charged at check-in or online in advance — pre-paying online is usually cheaper than paying at the airport.
Seat Selection & Cabin Classes
Horizon Air’s Embraer 175 aircraft are configured with First Class, Premium Class, and Main Cabin seating matching Alaska Airlines’ standard cabin layout, in a comfortable 2-2 configuration with no middle seats.
How to Find the Cheapest Horizon Air Fares
Four habits that consistently lower what you pay.
Book in the Sweet-Spot Window
For most Horizon Air routes, fares tend to be most competitive when booked several weeks to a few months ahead of departure, rather than at the last minute or extremely far out.
Fly Midweek and Off-Peak
Tuesday, Wednesday, and Saturday departures are usually cheaper than Friday or Sunday, and red-eye or early-morning flights often undercut peak daytime departures.
Set Fare Alerts
Track your route and let price-drop notifications do the watching, instead of checking manually every day.
Price-Tracking Tip
Compare a fixed date range over a week or two before deciding — single-day price checks can be misleading.
Compare a fixed date range over a week or two before deciding — single-day price checks can be misleading.
Use Flexible Date Search
Searching a date range instead of one fixed day often surfaces Horizon Air fares that are noticeably lower just one or two days earlier or later.
Check-In & Day-of-Travel
Online Check-In
Online and mobile check-in generally opens 24–48 hours before departure, letting you select or confirm your seat and download your boarding pass in advance.
Airport Arrival Times
Arrive with enough buffer for check-in, bag drop, and security — this matters more on international Aegean Airlines routes than short domestic hops.
Domestic vs. International Cutoff
International check-in and bag-drop counters usually close earlier relative to departure than domestic ones, so double-check your specific route’s cutoff.
