Any pilot under over 2000 seniority has a projected flow time of 7.5+ years. Even if that estimate turns out to be super conservative and they flow 2 years early that's 5.5 years to flow. Assuming 6 months worth of training, vacation, and sick time during their first 3 years. 30 months * 35 hours a month = 1050 hours by the end of year 3. So even if the flow goes much faster than predicted a reserve pilot flying 35 hours a month will spend over 2 years as a captain.
