Southwest Airlines has once again revised its policy regarding plus-size passengers, allowing airport agents to provide an additional seat free of charge if adjacent seats are available. This update follows significant backlash from passengers who criticized the airline's previous policies, which required certain travelers to purchase extra seats if they were deemed to encroach upon neighboring spaces. The airline stated that if no additional seats are available, passengers may need to take a later flight. This change aims to restore some flexibility after complaints, including one from Ruby Cosby, who felt unfairly singled out when told she had to buy an extra seat. She highlighted concerns about the lack of clear guidelines for enforcement, emphasizing the need to avoid discrimination. Southwest Airlines continues to encourage customers to purchase additional seats in advance to prevent complications at the airport. The airline is also in the process of overhauling several long-standing practices, including moving from open seating to assigned seating for the first time.
