re: When will plus-size airline passengers get their body size-justice?

What is your policy for Customers of size?
Booking

Customers who encroach upon any part of the neighboring seat(s) may proactively purchase the needed number of seats prior to travel to ensure the additional seat(s) is available. The armrest is considered to be the definitive boundary between seats; the width of the narrowest and widest passenger seats (in inches) is available on our Flying Southwest page . The purchase of additional seats serves as a notification of a special seating need and allows us to adequately plan for the number of occupied seats onboard . It also helps us ensure we can accommodate all Customers on the flight for which they purchased a ticket and avoid asking Customers to relinquish their seats for an unplanned accommodation. Most importantly, it ensures that all Customers onboard have access to safe and comfortable seating. You may contact us for a refund of the cost of additional seating after travel. If you prefer not to purchase an additional seat in advance , you have the option of purchasing just one seat and then discussing your seating needs with the Customer Service Agent at the departure gate. If it’s determined that a second (or third) seat is needed, you’ll be accommodated with a complimentary additional seat.

so that lardasses can buy an extra seat for the flight, then get refunded after the flight? so why cant i buy one seat for me & one for my wife, and then get refunded for one? whats the difference?
