Southwest Airlines Changes Policy for Plus-Size Passengers, Requires Extra Seat Purchase.

Southwest Airlines is ending its 'Customer of Size' policy, which allowed plus-size passengers to secure extra seating without upfront costs. Starting January 27, passengers who cannot fit comfortably in one seat must purchase an additional seat in advance. Refunds for the extra seat will only be granted under certain conditions.

Southwest Airlines has announced significant changes to its seating policy for plus-size passengers, effective January 27, 2026. The policy, which has long allowed these passengers to book an additional seat and apply for a refund post-travel, is now being revised to require upfront payment for the extra seat.

Under the new policy, plus-size passengers who cannot fit comfortably within the armrest boundaries of a standard seat must purchase an additional seat in advance. This change aims to reduce in-flight disruptions and align with Southwest's broader shift to assigned seating. The airline has stated that the new policy is not a new fee but a requirement to secure the extra seat at the time of booking, ensuring smoother operations for both passengers and crew.

Refunds for the second seat will only be granted under specific conditions, including if the flight departs with at least one open seat and both tickets were booked in the same fare class. The airline has also clarified that plus-size customers traveling on itineraries with Southwest partner carriers must purchase an additional, non-refundable seat directly through the partner carrier.

This policy change reflects an industry-wide trend toward managing cabin space more efficiently. With the rise in carry-on baggage and the increased demand for seat space, airlines are under pressure to maintain punctual boarding and avoid delays. Southwest's move follows similar policies introduced by other carriers to address seating conflicts and enhance in-cabin safety and comfort.

Critics argue that the policy may disproportionately impact passengers with larger body types and raise concerns about accessibility in air travel. However, supporters highlight the importance of balancing passenger comfort with the rights of others.

The policy change also reflects Southwest's broader financial pressures and its need to increase profitability amid rising operational costs and investor demands. The airline has previously eliminated perks such as free bag allowances to boost revenue, and this latest shift is part of an ongoing strategy to align with industry trends while maintaining profitability.
