Southwest Assigned Seating Policy: Complete Guide [2026]

Last Updated on July 28, 2026 by Daniel Globe

For more than 50 years, Southwest Airlines was the last major U.S. carrier without assigned seats — but that changed for good on January 27, 2026. Southwest now uses assigned seating, four distinct fare bundles, and eight numbered boarding groups, replacing the open-seating, first-come-first-served system many travelers grew up with. Here is exactly how the new system works and how to get the seat you want on your next flight.

Southwest’s new assigned seating policy, explained

Southwest Airlines now assigns every passenger a specific seat, either at booking or at check-in, depending on the fare purchased. The airline made the switch after internal research revealed that 80% of current customers and 86% of potential customers preferred assigned seating over the old open-boarding model, with open seating frequently cited as a primary reason travelers selected competing carriers.

There are three distinct seat categories on Southwest flights:

Extra Legroom Seats

Located in the front rows and exit rows, Extra Legroom seats offer three to five additional inches of seat pitch, earlier overhead bin access, and a complimentary premium beverage on flights over 251 miles.

Preferred Seats

Standard-legroom seats located near the front of the cabin, offering a quicker exit upon arrival and better overhead bin availability without the legroom upgrade fee.

Standard Seats

Standard-legroom seats located toward the middle and back sections of the cabin.

Southwest’s four fare bundles and what they include

Your chosen fare bundle controls both when you can select your seat and how early you board the aircraft:

Basic Fare

The lowest-cost option. Basic fares do not include advance seat selection; a Standard seat is automatically assigned at check-in. This fare is nonrefundable, and changes are permitted only by upgrading to a higher fare bundle.

Choice Fare

Allows you to select a Standard seat at the time of booking while preserving Southwest’s traditional flexibility, including zero change or cancellation fees.

Choice Preferred Fare

Adds the ability to select a Preferred seat near the front of the cabin at booking at no extra cost, alongside priority airport check-in and security lanes where available.

Choice Extra Fare

The top-tier bundle, replacing the former Business Select fare. Choice Extra includes Extra Legroom seat selection at booking, boarding in Groups 1–2, two free checked bags, and the highest Rapid Rewards point earning rate.

How the new Groups 1–8 boarding order works

Boarding position is no longer determined by how quickly you check in 24 hours before departure. Instead, boarding order is established by seat location, fare bundle, elite status, and credit card privileges.

Boarding privileges also extend to travel companions. Elite status and cardmember boarding benefits cover up to eight passengers traveling on the same reservation, while Companion Pass holders automatically receive the higher boarding benefit between themselves and their designated companion.

What happened to EarlyBird Check-In

EarlyBird Check-In and Upgraded Boarding — the legacy paid add-ons used to secure early A/B/C boarding spots — were officially retired after January 26, 2026. They have been replaced by Priority Boarding, a standalone upgrade granting access to Group 1 boarding. Priority Boarding can be purchased online or via the app between 24 hours and 60 minutes prior to departure, with pricing variable by route.

Finding the best seat for your travel needs

With assigned seating, you can choose a seat based on personal preference well before departure rather than rushing onboard to claim a spot. If legroom is your main concern, an Extra Legroom seat in the front rows or exit rows is ideal, provided you meet FAA physical and age requirements for exit rows. If you travel with young children or prefer a quieter flight, Standard seats near the forward half of the cabin offer a smooth experience. Seats directly over the wings generally absorb the effects of turbulence best, while window seats near the front or rear offer unobstructed viewing angles for takeoff and landing.

Booking seats for families and groups

Families and travel groups on the same confirmation number are assigned to the same boarding group automatically. When booking Choice, Choice Preferred, or Choice Extra fares, passengers can select adjacent seats during check-out rather than coordinating seating upon boarding. Booking early remains the most reliable strategy to secure adjacent seats, as seat maps fill up quickly on popular flight routes.

Managing seat changes and same-day flight updates

If you need to change your seat assignment after booking, you can do so through the Southwest app or on southwest.com up until departure, subject to availability. Passengers on Choice or higher fares can switch between open seats within their eligible tier for free, or pay the price difference to upgrade to Preferred or Extra Legroom seats. For passengers taking advantage of same-day standby or same-day flight changes, seat assignments are provided at the gate when the standby list is cleared based on remaining seat availability.

Updated A-List and credit card boarding benefits

Southwest’s loyalty status remains highly valuable under the assigned seating structure, with enhanced perks:

• A-List Members: Can select a standard-legroom seat at booking free of charge, with the option to upgrade to an available Preferred or Extra Legroom seat within 48 hours of departure.
• A-List Preferred Members: Can select any available seat in the cabin, including Extra Legroom seats, at the time of booking at no extra charge.
• Rapid Rewards Credit Cardmembers: Receive minimum Group 5 boarding status if not already assigned an earlier group based on fare tier or status — a benefit that extends to up to eight companions on the same booking.

Updated Customer of Size policy

Southwest updated its Customer of Size policy alongside the seating transition. Passengers who require additional seat space are now requested to proactively purchase a second seat at the time of booking to guarantee seating availability. This replaces Southwest’s former policy of issuing a complimentary extra seat at the gate, aligning its process with broader industry standards while ensuring cabin space is accurately managed.
