Southwest Airlines is updating its seating and pricing policy for plus-sized passengers, requiring those who cannot fit comfortably between a seat’s armrests to purchase an additional seat in advance.
According to The Independent, the new rule is set to take effect on January 27, coinciding with the airline’s upcoming switch to assigned seating — a major change from its current open boarding process.
Southwest’s current “Customer of Size” policy allows travelers to purchase a second seat before flying, with the option to receive a refund after the trip or to request an additional seat for free at the airport if one is available. However, the new policy will require passengers who need extra space to buy that second seat up front, rather than waiting until check-in.
Refund Options Available If Flight Isn’t Fully Booked
Under the updated policy, plus-sized passengers who purchase a second seat will still be eligible for a refund if the flight isn’t fully booked.
The airline said the change is meant to ensure comfort and fairness for all passengers while avoiding last-minute seating conflicts or flight delays.
Southwest’s new policy also notes that if a passenger who requires an extra seat does not purchase one before the flight, they’ll be required to buy the additional ticket at the airport. If that particular flight is already full, the airline will book them on the next available flight instead.
Airline Says It’s About Comfort, Not Punishment
In a public statement, Southwest Airlines clarified that the new rule isn’t meant to single out passengers based on body size, but rather to make sure each customer’s comfort and safety are prioritized.
The company explained that travelers should proactively purchase the number of seats they need to sit comfortably and that doing so also ensures those seats remain available when booking.
However, The Independent reports that Southwest has not provided clear guidelines on how many seats certain passengers should buy, stating instead that the requirement will be handled on a “case-by-case basis.”
The move has sparked debate online, with some travelers arguing the change could create confusion and added costs for larger passengers, while others say it provides clarity for seating arrangements and improves flight logistics.
Other Policy Changes: Legroom Charges and Red-Eye Flights
Along with the “Customer of Size” update, Southwest Airlines is also rolling out a new seat-pricing model that charges passengers extra for additional legroom — a first for the low-cost carrier known for its one-class cabin model.
The airline will also begin offering red-eye flights, expanding its schedule to include late-night and early-morning travel options.
These changes reflect Southwest’s ongoing effort to modernize its fleet and operations while adapting to growing competition in the airline industry.
