Southwest Airlines has eliminated its well-known “customer of size” policy, which allowed larger passengers to request a second seat at no additional charge.
Starting from January 27, 2026, passengers of larger sizes or individuals with obesity will need to purchase an extra seat in advance to ensure their space on board.
The airline stated that the armrest will be regarded as "the definitive boundary between seats," and customers who exceed this will have to pay for an additional seat before traveling.
In addition, refunds for that second seat will be subject to stricter conditions. They will only be considered if the flight is not full, the seats are in the same class, and the request is made within 90 days prior to the trip.
The measure has generated strong criticism among passengers, who describe it as a setback in inclusion and believe it will significantly increase travel costs for people with larger physiques.
Southwest Airlines announces other changes that may not please its customers
This new seating policy aligns with other changes in the company. In March, Southwest Airlines announced that, for the first time in its history, it will abandon its open boarding system and begin assigning seats starting in 2026.
The change aims to reorganize the flight experience and increase profitability, although it marks the end of a distinctive feature that characterized the airline for decades.
They also said goodbye to free luggage
Southwest from May 28, 2025 will charge for checked luggage. Until that time, the airline allowed the check-in of two bags at no extra cost, a benefit that set it apart in the competitive U.S. market.
The new fees are $35 for the first suitcase and $45 for the second, except for customers with special benefits from the Rapid Rewards program or with Business Select tickets.
The airline is also introducing more affordable basic fares, sales through external platforms such as Expedia, overnight flights, and other services that signify its transition to a more conventional model.
The pressure from shareholders, the massive layoffs announced in July, and the need to increase revenue after years of losses have driven these changes.
Other airlines and their policies for large-sized passengers
Southwest is not the only airline with policies regarding larger passengers:
- Alaska Airlines requires the purchase of a second seat if the armrest cannot be raised.
- American Airlines recommends booking two seats and offers assistance at the airport.
- Delta Air Lines may reassign the passenger to another seat or flight without prior purchase.
- Frontier Airlines requires the purchase of an additional seat if both armrests cannot be lowered.
