That's Southwest's business model. Nobody preselects seats. If enough people start paying for early bird check in, that will likely affect later passengers' abilities to be seated together. That wouldn't be an issue for a family with small children, since, even in relation to Orlando, a parent would be allowed to board with a child (usually) four and under between the A and B boarding groups. Extended family - i.e. a grandparent - would still have to board with their proper group.
Southwest no longer allows parents with children to board first. At least they didn't last time we flew.
I'm relatively certain PanAm is once again defunct. If not, at the VERY least, they pulled out of their very short stay in Portsmouth several years ago.
What does that have to do with anything???
Mm, yes. They probably talked with several passengers who had paid in advance to select their seats and so were reluctant, or apparently entirely unwilling, to give up the seats for which they'd paid extra.
No ~ I spoke to several EMPLOYEES about our seats. And really? You think we were the ONLY people on the entire plane who didn't pay to select our seats?
And by they ~ to the PP who said they don't ask they age.... no they do better ~ they ask for the DATE OF BIRTH. Unless that can't figure out the age by the year a person was born. So perhaps you yourself have not flown Airtran.
