I have had one checkride bust in my life, 8 years ago. We discussed it during the interview. No other fails. I resigned during training from a regional 11 years ago - moving from CFI'ing into a jet was a huge jump for me, and I just wasn't up to it at the time. That was also discussed during the interview. I really don't think those things were any issue, as I admitting to them, and told them what I learned from those mistakes. I have no traffic tickets in the past 2 decades, and never any DUI's or arrests.

I don't have any confirmation about the six others, that's just what I was told by a classmate. I can only speak about myself for sure.

I'm really not trying to bash Frontier, or scare anyone away. I'm just sharing my own experience. I'm hoping just maybe I can figure out something I can do different/better on my next big interview.
