I travel a great deal, with many of my return flights happening on Thursday and Friday evenings. I cannot help but notice that, on late evening end of week flights out of places like NYC, there seem to be a lot of single young women traveling alone. They are usually in casual clothes, so these are not girls coming from the office. Most of them are quite attractive, which makes for some nice eye candy for this weary road hound.
I wonder how many of these girls work in adult entertainment. I'm guessing that the % is surprisingly high.
When I worked at LAX we used to see that all the time on flights to LAS on Friday nights. Many of them school teachers. We referred to them as weekend warriors. :)
