The frequency argument is an interesting one. This recent survey seems to indicate that travel maps pretty closely (within a percent or three) to population of the area which I wasn't actually expecting (sure, lobbying group doing the research caveat caveat): http://airlines.org/wp-content/uploads/2016/04/2016Survey.pd...

It also looks like there's a pretty significant difference between Midwest and Plains states in terms of numbers - less people, many fewer airports.

I totally get why the stereotype kinda makes sense given a certain view of a large swath of the country (though I've generally found these to be poor guides) but the statement would've worked without the regional or gender modifier :)

This is also a bit raw for me because I JUST flew my kids to Disney haha
