How Southwest seats & boarding generally work now
The essentials under the 2026 assigned-seating model. Availability and price depend on fare, route and timing.
Since January 27, 2026, Southwest assigns seats rather than letting you pick any open seat on board. You can select or be assigned a specific seat before you fly.
Higher fares (Choice, Choice Preferred, Choice Extra) get better seat selection and access to extra-legroom seats; Basic is the most restricted, with your seat typically assigned at check-in.
If you're travelling as a family or group, book and select seats as early as you can — the best adjacent seats and extra-legroom rows go first on full flights.
Southwest now sells extra-legroom seating on many aircraft. It's limited and can sell out on popular flights, so choose early if it matters to you.
Rapid Rewards A-List and A-List Preferred members get priority boarding and better seat access. Add your Rapid Rewards number so any benefit applies.
Seat prices vary by route, cabin position and timing and change constantly, so we don't list amounts. Tell us your flight and we'll check what's open and reserve it for you.
Seat options by fare
General guidance under 2026 assigned seating — what's included and what's paid depends on your fare.
Boarding under the new model
Assigned seating changed boarding too — who goes first now depends on fare and status.
Board earlier
Priority

Board later
Basic
- Basic is the most restricted fare
