About SkyWest Airlines
SkyWest Airlines (IATA: OO) is the largest regional airline in the United States by fleet size, operating a large fleet of Embraer E175 and Bombardier CRJ-family regional jets. Unlike a typical regional carrier that flies for a single mainline partner, SkyWest is unique in that it operates flights under four different major airline brands, depending on the specific route: United Express, Delta Connection, American Eagle, and Alaska SkyWest.
SkyWest does not sell tickets under its own brand and has no independent fare class or reservation system. Each of its four mainline partners — United, Delta, American, and Alaska — handles reservations, ticket sales, pricing, and ground support for the SkyWest-operated flights on its respective routes. This makes SkyWest an important but largely invisible part of the US air travel network, quietly operating a substantial share of regional flying on behalf of the country's largest airlines.

How to Book SkyWest-Operated Flights
There is no separate SkyWest booking site, fare class, or independently searchable "SkyWest flight." SkyWest has no fare of its own — instead, depending on the specific route, SkyWest-operated flights are sold as United Express, Delta Connection, American Eagle, or Alaska SkyWest.
To fly on a SkyWest-operated aircraft, you need to search and book through whichever mainline carrier's brand applies to your route — united.com, delta.com, aa.com, or alaskaair.com — or via FareOptic's search for that specific airline. Your itinerary, ticket, and flight number will show as that mainline carrier's flight, even though SkyWest's aircraft and crew operate it. Delta Connection flights operated by SkyWest are booked the same way, directly through Delta, since FareOptic does not yet have a dedicated Delta Air Lines page.
If you're looking to book a flight rather than research the operator, search one of SkyWest's partner airlines instead:
SkyWest Crew Bases
SkyWest operates from numerous crew bases across the US to support its four partner networks, including these well-known airports.
Cabin Class on SkyWest-Operated Flights
SkyWest flies regional jets in a single Economy cabin, configured to whichever partner brand's standards apply on that route.
Economy
- ✓Regional jet cabin — Embraer E175 and Bombardier CRJ-family aircraft
- ✓Single-class Economy layout
- ✓Seat pitch and product set by whichever partner brand sold the ticket
- ✓United Express, Delta Connection, American Eagle, or Alaska SkyWest fare, depending on route
- ✓No SkyWest-branded seating or service tiers
Earning Miles on SkyWest-Operated Flights
SkyWest does not have its own loyalty program. Because every ticket is sold and issued by one of its four mainline partners, passengers earn miles in whichever program applies to their specific flight — United MileagePlus, Delta SkyMiles, American AAdvantage, or Alaska Mileage Plan — exactly as they would on that partner's own mainline aircraft.
Baggage Policy
Baggage policy on SkyWest-operated flights varies entirely by which partner brand your ticket was sold under — there is no separate SkyWest baggage rule.
| Bag / Policy | SkyWest-Operated Flights (all partners) |
|---|---|
| Carry-on bag | Follows the policy of whichever partner brand sold your ticket (United, Delta, American, or Alaska) |
| Checked baggage | Follows the checked baggage fees and allowances of the mainline partner whose brand appears on your ticket |
| Gate-checked items | Common on smaller regional jets due to limited overhead bin space |
| Fare class differences | Allowance depends entirely on the partner airline's fare class purchased — SkyWest does not set its own baggage policy |
Always check united.com, delta.com, aa.com, or alaskaair.com — whichever brand sold your ticket — for the exact baggage allowance. SkyWest does not set or vary this policy independently.
Check-In & Boarding
Check In via the Partner Brand
Check in at united.com, delta.com, aa.com, or alaskaair.com using your confirmation number for that airline — whichever sold your ticket.
Standard Partner Boarding Groups
Boarding follows the boarding process of whichever mainline partner sold your ticket, regardless of SkyWest operating the aircraft.
Regional Jet Gates
SkyWest flights typically depart from regional jet gates or remote stands at partner hub airports — allow a little extra time to reach the gate.
Cancellation & Change Policy
Governed Entirely by the Partner's Fare Rules
Partner Fare RulesBecause tickets are sold under United, Delta, American, or Alaska fares, cancellation and change rules on SkyWest-operated flights follow that partner's policy exactly.
24-Hour Risk-Free Cancellation
All FaresAs US carrier tickets, most fares booked at least 7 days before departure can be cancelled within 24 hours of purchase for a full refund, including on SkyWest-operated segments.
Basic Economy Restrictions
Basic EconomyIf booked on a Basic Economy fare with any of the four partners, changes may not be permitted at all — this applies the same way whether the flight is mainline or SkyWest-operated.
Manage via the Partner Airline
Partner OnlyAll cancellations, changes, and refund requests are handled through whichever of United, Delta, American, or Alaska sold your ticket — SkyWest has no independent customer service channel for ticketing.
In-Flight Experience on SkyWest-Operated Flights
Regional Jet Cabin
Embraer E175 and CRJ-family aircraft feature a smaller single-aisle cabin, typical of regional jets used for shorter partner-branded routes.
Standard Partner Service
Complimentary soft drinks and snacks are offered on most flights, consistent with the standard domestic service of whichever partner sold the ticket.
Limited or No Wi-Fi
Wi-Fi availability on SkyWest-operated regional jets varies by aircraft and partner brand — check availability for your specific flight.
Limited Overhead Bin Space
Smaller regional jets have less overhead bin space, so larger carry-on bags are frequently gate-checked at no charge.
Tips for Booking a SkyWest-Operated Flight
- 1.Check which brand your flight is sold under — United Express, Delta Connection, American Eagle, or Alaska SkyWest — before assuming baggage, loyalty, or change rules; each partner sets its own.
- 2.Search united.com, delta.com, aa.com, or alaskaair.com directly, or use FareOptic's page for that specific airline — there is no separate SkyWest site to book.
- 3.Look for "Operated by SkyWest Airlines" in the flight details of your itinerary to confirm which regional carrier is flying your route.
- 4.Your flight number will always show as the partner airline's number, even on SkyWest-operated aircraft — this is normal for regional partner flying across the US industry.
- 5.Expect a smaller Embraer E175 or CRJ-family regional jet cabin rather than a larger mainline aircraft on these segments.
- 6.Any loyalty number, seat selection, or upgrade request should be managed through whichever of the four partner programs applies to your ticket.
- 7.Because overhead bin space is limited on regional jets, consider gate-checking larger bags for free rather than fighting for bin space.
- 8.Contact the partner airline's customer service, not SkyWest, for any ticketing, refund, or itinerary questions.

Do I earn miles on a SkyWest-operated flight?
Yes. Since the ticket is sold and issued by the mainline partner, you earn miles in whichever program applies to your specific flight — United MileagePlus, Delta SkyMiles, American AAdvantage, or Alaska Mileage Plan — exactly as you would on that partner's own mainline aircraft.
