There used to be a black market for airline tickets before they started checking ID. You would see classified ads "DFW-LAX, Male January 14-29" and naming a price.
The conspiracy theorists quickly assumed the airport ID process was put in place to stop this kind of activity. Of course, frequent flyer programs were much more generous back then so it might have been worth it to get people to fly for you.
As to the OP, you could probably get away with it, but you're asking for trouble doing this in the current security climate.
