It is VERY interesting that they are only allowing Companion Pass use for children under the age of 18. We have two companion passes among the four of us and this negates one of them. I guess Southwest ran models to see what would happen with high companion pass usage and this was the compromise.
It's a good compromise because it allows some use of the companion pass, but it is going to be a real bummer for people that want to escape on a romantic trip using their companion pass.
