Southwest Airlines has recently implemented a new policy for plus-sized passengers, causing controversy among travelers. The new rule, effective January 27, 2026, requires passengers who cannot fit within the armrests of their seat to book an additional one before their flight. This change has sparked mixed reactions, with many expressing disappointment and concern over the potential increase in fares.

Previously, plus-sized travelers could request an extra seat and either apply for a refund or request a complimentary seat at the airport. However, under the new rules, this may no longer be an option and refunds are not guaranteed. A refund will only be granted if there is an empty seat on the flight and both tickets were purchased in the same booking class. This means that passengers can no longer assume that an extra seat will automatically qualify for a refund.

The National Association to Advance Fat Acceptance (NAAFA) has expressed disappointment in the change, stating that Southwest was previously seen as a friendly and customer-oriented company. Tigress Osborn, chair of NAAFA, told the New York Times, “Southwest was the only beacon of hope for many fat people who otherwise wouldn’t have been flying. And now that beacon has gone out.

While the increase in obesity rates worldwide is undeniable, some argue that airlines should also consider the trend of shrinking seats. In the UK, government statistics show that over 64% of adults are estimated to be overweight or living with obesity. However, readers of Metro have also pointed out that carriers may be offering smaller seats to fit more passengers. Some have called for aviation authorities to set minimum seat dimensions to ensure passenger comfort and safety.

In 2018, Congress asked the Federal Aviation Administration (FAA) to set seat-size minimums to protect passenger safety. The FAA then asked the public for their thoughts on airline seats, and received over 26,000 responses outlining the discomfort, health risks, and safety concerns associated with current seat sizes. The average legroom pitch on domestic flights in the US has decreased by 2 to 5 inches, and seat width has decreased by 2 inches since the 1980s.

Despite the trend of shrinking seats, a spokesperson for Southwest has stated that their seat sizes will not be changed or reduced in any way. However, the new policy for plus-sized passengers has raised concerns about comfort and safety for all passengers, as well as the potential impact on fares. Only time will tell how this new rule will affect Southwest’s reputation as a customer-first airline.
