It won't come down to people not showing up for class; I think there will be a steady flow. I joined last summer because my regional was dying, so I'd be a hypocrite if I then said that people shouldn't come here for lackluster pay.

What I DO think could be a factor is pilot attrition. As all airlines keep hurting for pilots, and frontier continuing to hold out on pay, I think you'll see greater and greater attrition. The training department can only handle X amount of people in the training center/sims. With plans of growth, the need to hire and upgrade, just a small increase in attrition could be catastrophic. Heck, the big 3 could tank F9 by taking just a few more pilots per month. They may need to "incentivize" people staying here. I'll gladly vote with my feet.

But what do I know, I'm just a dumb pilot.
