Do you trust that airline seating changes improve your overall travel experience?

Southwest Airlines ended its 54-year open-seating policy on January 27, 2026, officially transitioning to a system featuring seat assignments. The move aligns the carrier with industry standards through a new tiered fare structure and eight distinct boarding groups.

Why it matters

The change follows market research indicating that 80% of existing customers and 86% of potential passengers preferred assigned seating over the previous model. The airline implemented the update to satisfy investor demand and bolster its financial performance.

The airline expects its 2025-2026 initiatives to generate $1.8 billion in additional earnings before interest and taxes. This strategy affects the carrier's entire fleet of 803 Boeing 737 aircraft.

The players

Southwest Airlines

Based in Dallas, this major carrier operates a fleet of 803 Boeing 737 aircraft across the United States.

Delta Air Lines

This airline secured the top position in the 2026 American Customer Satisfaction Index with a score of 79.

The details

Under the new system, travelers on eligible fares select seats in advance, while Basic fare passengers receive assignments at check-in. Boarding priority within the eight groups is determined by a combination of fare type, elite status, and credit card usage.

Southwest Airlines first announced the seating change in 2024.
The airline held an 80 score on the ACSI index during 2025.
Southwest began assigned seating across its network on January 27, 2026.
Southwest received a 77 ACSI score in 2026.

Travel Outlook

The airline's move represents a major shift from its long-standing open-seating model to match the standard practices of legacy carriers. This alignment is designed to capture market share and improve financial stability amidst competitive pressures in the U.S. aviation industry.

Passengers must now anticipate specific seat assignments rather than competing for spots during the boarding process. Travelers should check their fare type carefully, as Basic fare customers receive their assignments only at check-in.

The takeaway

Travelers should verify their boarding group status in advance to understand their relative priority under the new system. This change effectively ends the era of open seating, requiring passengers to adapt to a structured, fare-dependent boarding process.
