Ascent Status Challange question

I am currently doing the Frontier Status Challenge for Ascent Status. Due to the recent change to fares, the status is more valuable now, so I really want to complete it. I currently have three one-ways scheduled, that I intend to keep, before the end of the challenge. To succeed in the challenge, I need a minimum of 4 one-ways within the 60 day period. My travel plans have changed over the next few months so, as of now, I'm not planning to travel any more within the challenge period. If I were to buy one of Frontier's cheap one-way tickets (~$29) and not use it (i.e. not show up for the flight) would this count for my fourth flight? Would there be any sort of no-show fee?

Thanks in advance!
