Southwest Airlines has maintained a notable policy for 'Customers of Size,' allowing larger passengers to purchase an additional seat and receive a refund later. This process is straightforward, as passengers only need to select an extra adult fare and request a refund after the journey.
For over five decades, Southwest's open seat policy has allowed passengers to choose their seats upon boarding. Customers of Size can board early to select two suitable seats. However, this policy will change next year, potentially affecting the Customer of Size procedure.
A Customer of Size is defined by Southwest as any passenger who "encroaches upon any part of the neighboring seat," with armrests serving as boundaries. Passengers needing an empty seat must purchase it during booking and will be refunded regardless of flight load.
