I did head over to the SW site to see what youth fares were all about. Now, I'm really confused!!! When you book, on-line, it only lists adults-age 2-65, and then seniors-65+, no youth. So, I went to one of the sidebar menu thingies, found that children, flying accompanied, can qualify for youth fares, but you have to call SW directly to do this. But since there was no way to do it on-line, did the OP actually call SW to get the youth fares?? Just curious.
