I agree, these do not look like significant differences. Using a margin of error of 3-4%, which is typical for a study of the size they conducted (I clicked through the links to find some detail on methods at http://apex.aero/Resources/Passenger...3/Default.aspx), a more accurate headline would be "No Statistically Significant Difference Between Male, Female Travelers". But that wouldn't get clicks to sell ads.

I'm curious if there's more of a difference between regular travelers and infrequent ones. For example, my wife sweats getting to the airport on time while I don't. But I chalk that up more to our experiences than our genders. As a frequent traveler I know how long it takes to get to the airport, both with and without traffic, as well as how long it takes to get through security, both at peak times and quiet times. I use this knowledge to plan a schedule that balances the value of my time against risk mitigation. My wife, an infrequent traveler, does not know these things so she plans excessive amounts of time for them out of an abundance of (poorly informed) caution.
