About Horizon Air
Horizon Air (IATA: QX) is a US regional airline wholly owned by Alaska Air Group. It does not sell tickets under its own brand. Instead, it operates a fleet of Embraer E175 regional jets on behalf of Alaska Airlines, flying 100% of its scheduled flights as Alaska Horizon — Alaska's regional brand for shorter Pacific Northwest and West Coast routes flown with smaller aircraft.
Horizon Air has been one of Alaska Air Group's original regional partners for decades, and today it flies exclusively and fully integrated under the "Alaska Horizon" name. Because Horizon Air has no independent fare class or booking system, every ticket on a Horizon Air-operated aircraft is sold, priced, and ticketed by Alaska Airlines — the flight number appears as an Alaska Airlines (AS) flight even though Horizon Air's crew and aircraft operate it.

How to Book Horizon Air Flights
There is no separate Horizon Air booking site, fare class, or independently searchable "Horizon Air flight." Horizon Air operates exclusively as Alaska Horizon, meaning every flight it flies is sold, ticketed, and priced entirely by Alaska Airlines.
To fly on a Horizon Air-operated aircraft, search and book an Alaska Horizon flight at alaskaair.com or through FareOptic's Alaska Airlines search. Your itinerary, ticket, and flight number will show as Alaska Airlines (AS), even though the aircraft and crew are provided by Horizon Air — this is standard practice for regional partner flying in the US airline industry.
If you're looking to book a flight rather than research the operator, search Alaska Airlines flights instead:

Earning Miles on Horizon Air-Operated Flights
Horizon Air does not have its own loyalty program. Because every ticket is sold and issued by Alaska Airlines, passengers earn Alaska Mileage Plan miles and applicable elite-qualifying credit on Horizon Air-operated Alaska Horizon flights exactly as they would on a mainline Alaska flight.
Baggage Policy
Since tickets are sold as Alaska Airlines fares, baggage policy on Horizon Air-operated flights follows Alaska's policy exactly — there is no separate Horizon Air baggage rule.
| Bag / Policy | Alaska Horizon (QX-operated) |
|---|---|
| Carry-on bag | Follows Alaska Airlines' carry-on policy |
| Checked baggage | Follows Alaska Airlines' checked baggage fees and allowances |
| Gate-checked items | Common on smaller E175 regional jets due to limited overhead bin space |
| Fare class differences | Allowance depends on the Alaska fare class purchased (Saver, Main, First) |
Always check alaskaair.com for the exact baggage allowance tied to your fare class — Horizon Air does not set or vary this policy independently.
Check-In & Boarding
Check In via Alaska Airlines
Check in at alaskaair.com or the Alaska Airlines app using your Alaska confirmation number, exactly as you would for any other Alaska Horizon flight.
Alaska Boarding Groups
Boarding follows Alaska Airlines' standard boarding group process, regardless of which regional operator is flying the aircraft.
Regional Jet Gates
Horizon Air flights typically depart from regional jet gates or remote stands at Alaska hub airports — allow a little extra time to reach the gate.
Cancellation & Change Policy
Governed Entirely by Alaska's Fare Rules
Alaska Fare RulesBecause tickets are sold as Alaska Airlines fares, cancellation and change rules on Horizon Air-operated flights follow Alaska's policy exactly — there is no separate Horizon Air rule set.
24-Hour Risk-Free Cancellation
All FaresAlaska Airlines tickets booked at least 7 days before departure can be cancelled within 24 hours of purchase for a full refund, including on Horizon Air-operated segments.
Saver Fare Restrictions
Saver FareIf booked on an Alaska Saver fare, changes may not be permitted at all — this applies the same way whether the flight is mainline Alaska or a Horizon Air-operated Alaska Horizon segment.
Manage via Alaska Airlines
Alaska OnlyAll cancellations, changes, and refund requests are handled through alaskaair.com or Alaska Airlines customer service — Horizon Air has no independent customer service channel for ticketing.
In-Flight Experience on Horizon Air-Operated Flights
Regional Jet Cabin
The Embraer E175 features a comfortable single-aisle cabin with 2x2 seating, typical of the regional jets used for shorter Alaska Horizon routes.
Standard Alaska Horizon Service
Complimentary soft drinks and snacks are offered on most flights, consistent with Alaska Airlines' standard domestic service on regional jets.
Wi-Fi on Most Aircraft
Many Horizon Air E175 aircraft offer inflight Wi-Fi consistent with Alaska's mainline fleet, though availability can vary by specific aircraft.
Limited Overhead Bin Space
Smaller regional jets have less overhead bin space than mainline aircraft, so larger carry-on bags are sometimes gate-checked at no charge.
Tips for Booking a Horizon Air-Operated Flight
- 1.Search alaskaair.com or FareOptic's Alaska Airlines page — there is no separate Horizon Air site to book directly.
- 2.Look for "Operated by Horizon Air" in the flight details of an Alaska Horizon itinerary to confirm which regional partner is flying your route.
- 3.Your flight number will always show as an Alaska Airlines (AS) flight number, even on Horizon Air-operated aircraft — this is normal for regional partner flying.
- 4.Expect a smaller Embraer E175 regional jet cabin rather than a larger mainline Alaska Airlines aircraft on these segments.
- 5.Any Mileage Plan number, seat selection, or upgrade request should be managed the same way as any other Alaska Airlines reservation.
- 6.Because overhead bin space is limited on regional jets, consider gate-checking larger bags for free rather than fighting for bin space.
- 7.If your itinerary changes to a different operating carrier, your Alaska Airlines ticket and fare rules remain unchanged.
- 8.Contact Alaska Airlines customer service, not Horizon Air, for any ticketing, refund, or itinerary questions.

Frequently Asked Questions
Everything you need to know about Horizon Air and booking its Alaska Horizon flights on FareOptic
Can I book Horizon Air flights directly?
No. Horizon Air does not sell tickets under its own brand and has no independent booking site or fare class. It operates 100% of its flights as Alaska Horizon on behalf of Alaska Airlines, so every seat on a Horizon Air-operated aircraft is sold and ticketed as an Alaska Airlines flight. To fly on a Horizon Air-operated plane, you book an Alaska Airlines flight through alaskaair.com or a travel platform like FareOptic.
Why does my Alaska Airlines flight say the plane is operated by Horizon Air?
Alaska Air Group wholly owns Horizon Air and uses it to fly shorter Pacific Northwest and West Coast routes under the Alaska Horizon brand using smaller Embraer E175 regional jets. Your ticket, flight number, and fare are all Alaska's — Horizon Air simply operates the aircraft and crew for that specific flight segment.
Is Horizon Air the same company as Alaska Airlines?
No, though they are closely linked. Horizon Air is a separate operating subsidiary wholly owned by Alaska Air Group, the same parent company that owns Alaska Airlines. Horizon flies exclusively as a regional feeder for Alaska, branded as "Alaska Horizon."
What aircraft does Horizon Air fly?
Horizon Air operates a fleet of Embraer E175 regional jets, configured to Alaska Horizon specifications for short and medium-haul routes across the Pacific Northwest and West Coast.
Do I earn Alaska Mileage Plan miles on a Horizon Air-operated flight?
Yes. Since the ticket is sold and issued by Alaska Airlines, passengers earn Alaska Mileage Plan miles and any applicable elite-qualifying credit exactly as they would on a mainline Alaska-operated flight.
What are Horizon Air's crew bases?
Horizon Air's Alaska Horizon operations are anchored by crew bases at Seattle-Tacoma International Airport (SEA) and Portland International Airport (PDX), two of Alaska Airlines' key Pacific Northwest hubs.
