Be careful bud...I know a Flight Attendant that did what I think you are going to do, and her non-rev privelages were yanked without her knowing. She then had to pay for her way home from the Caribbean.
Just trip trade! I used to make "mini vacations" for myself all of the time! That way, I didn't have to chash in my paid vacation! Learning how to "work the system" will come with experience...trust me...
