In 2026, Southwest passengers will be allocated seats.

In an effort to improve the traveler experience, Southwest revealed intentions to do away with open seating and implement assigned seating. Additionally, the business will provide first-rate seating selections. The sale of assigned tickets for flights in early 2026 will start in the second half of 2025. More improvements are also being made, such as more comfortable seats, bigger overhead bins, updated in-seat electricity, and quicker WiFi.
