Southwest Airlines Forces Plus-Size Flyers to Pre-Pay Double for Seats in Major

The commercial aviation sector is seeing major service changes. Southwest Airlines, a key low-cost carrier, is revamping its 'Customer of Size' policy. This policy was once known as the most generous for plus-size passengers in the United States. The airline will implement the new rules on January 27, 2026.

Under the updated policy, travelers must buy a second ticket at the time of booking. This applies if they cannot fit between a single seat's armrests. Critics call this change a "massive blow" to plus-size travelers.

Major Policy Shift and Financial Impact

This new rule is part of a larger plan to modernize Southwest's business model. The airline is moving away from its famous open seating policy. It is now shifting toward a traditional assigned seating system.

For many loyal plus-size travelers, this change creates a significant financial burden. They are now effectively forced to pay double for a single trip. This feels like a heavy "extra fee" just to reach their destination.

• The old policy allowed customers to request a complimentary extra seat at the gate.
• The new policy mandates the purchase of an additional seat in advance.
• The change coincides with the full implementation of assigned seating across the network.

New Refund Conditions

Under the previous rules, refunds for the extra seat were often guaranteed. The new policy introduces much stricter conditions for a refund.

• The flight must depart with at least one open seat.
• Both seats must be bought in the same fare class.
• The refund request must be submitted within 90 days of travel.

Extra seats purchased for itineraries involving a partner carrier are explicitly non-refundable. This is a key detail for travelers on connecting flights. The new structure means upfront costs and uncertainty about refunds.

Backlash and Industry Context

The announcement has caused sharp criticism from advocacy groups. Travel expert Jason Vaughn, founder of the Fat Tested Travel group, voiced strong concerns. He believes the changes reflect a loss of identity for the airline.

Vaughn pointed out that higher costs may force some travelers to "squeeze" into a single seat. This is done just to avoid paying double the price. Such actions make the flight miserable for them. It also creates a much more uncomfortable experience for neighboring passengers. This results in less personal space for everyone on the plane.

Broader Operational Changes

The Southwest Airlines Customer of Size policy change is not isolated. It is part of a broader revenue diversification strategy. The airline also recently ended its "bags fly free" policy. It now charges $35 for the first checked bag.

Southwest is also introducing new fare bundles. These include options for extra legroom and preferred seating. Airline officials state the updates aim to ensure safe and comfortable seating for all. They also want to adapt to the new assigned seating model. This shift aligns Southwest with the business models of other major U.S. carriers like American Airlines and United Airlines. These changes are a significant piece of commercial aviation news for the industry and consumers. aviation news
