Southwest Airlines Alters Policy for Plus-Size Passengers

Southwest Airlines has decided to discontinue its well-known "customer of size" policy, which previously allowed plus-size passengers to request an additional seat without any extra charge. Starting January 27, 2026, individuals of larger size or those who are obese will need to purchase an extra seat in advance to ensure adequate space during their flight.

The airline has specified that the armrest will serve as the "definitive boundary between seats," and any passenger exceeding this limit will be required to pay for an additional seat prior to their trip. Moreover, refunds for the extra seat will be subject to stricter conditions. Refunds will only be considered if the flight is not fully booked, the seats are in the same class, and the request is made within 90 days before the travel date.

This policy change has sparked significant criticism among passengers, who describe it as a step backward in terms of inclusion, and believe it will considerably increase travel costs for those with larger bodies.

Southwest Airlines Announces Additional Changes That May Displease Customers

This new seating policy aligns with other updates in the company. In March, Southwest Airlines revealed that, starting in 2026, it will transition from its unique open seating system to assigned seating for the first time in its history. This shift aims to reorganize the flight experience and boost profitability, although it marks the end of a distinctive feature that set the airline apart for decades.

Farewell to Free Checked Bags

As of May 28, 2025, Southwest has begun charging for checked luggage. Previously, the airline allowed passengers to check two bags at no extra cost, a benefit that differentiated it in the competitive U.S. market. The new fees are $35 for the first bag and $45 for the second, except for customers with special benefits under the Rapid Rewards program or those holding Business Select tickets.

In addition, the airline is introducing more budget-friendly basic fares, expanding sales through external platforms like Expedia, offering overnight flights, and introducing other services that indicate a shift towards a more conventional business model. The pressure from shareholders, massive layoffs announced in July, and the necessity to increase revenue after years of financial losses have driven these changes.

Policies of Other Airlines for Plus-Size Passengers

Southwest is not alone in having policies regarding plus-size passengers:

• Alaska Airlines requires the purchase of a second seat if the armrest cannot be lowered.
• American Airlines suggests booking two seats and provides assistance at the airport.
• Delta Air Lines may reassign the passenger to another seat or flight without prior purchase.
• Frontier Airlines mandates the purchase of an additional seat if both armrests cannot be lowered.
