Southwest Airlines has updated its policy for plus-size passengers, removing the requirement to purchase an extra seat in advance.

•� � If adjacent seats are available, airport agents can now provide an additional seat at no extra cost.

•� � Passengers who do not reserve an extra seat beforehand still risk being unable to board their original flight if no additional seats are available.

•� � Southwest said the change is intended to create a more consistent and seamless travel experience, while still encouraging customers who may need extra space to book an additional seat in advance.
