Yeah, I base the three years for someone hired today. We are not expect significant additional growth right now. Probably top out around 2300 pilots. We have just under 2100 right now. Junior upgrade this round was around 1250. Assuming average attrition of 30/month, that gives about 28-35 months based on which point of that hiring curve. Guys hired earlier this year will upgrade faster. That huge push from last fall to today really messes up predictions based on current events. The questions is when will the plateau hit.
