There is about maybe 2 or 3 percent of the people I know where I work that actually BUY a positive space ticket without even trying to go space available. Foolish in my eyes that someone would buy a positive space ticket while working for the airlines. I can see it as a last resort or if you absolutely have to get to a destination at a certain window when the flights are just too full. I plan my vacations around availability of spaces on flights as a non rever. I'll go to Nicaragua for instance instead of going to Honolulu or have a back up plan if my destination is overloaded with pos pax. Hey, kids are back to school, that means.......it's time to non rev.
