Our attrition will not change with the majors hiring. Fractional pilots fly small planes not very often. Major computer filters favors mil and 121 (larger tonnage airframes and several hundred hours / year).
You say you're in your 30's. With more experinece you may learn not to make such baseless statements. In the first 3 years of this century well over 100 NJA (then EJA) pilots were eagerly hired by Delta, United, etc. Within months they were furloughed. That is another matter unrelated to their experience, however.
Flying small planes not very often? I blocked 160 hrs last quarter flying faster and higher than any airliner. I have also flown to hundreds more airports than any legacy pilot will ever see in their entire career. When we were still hiring, the retired legacy guys frequently commented on how much more challenging the fractional world is. Do you think that word has gone unoticed by their former collegues and bosses?
With the reduction in available military pilots retiring due to fewer being trained and longer commitments, I believe the fractional world will be a far riper orchard to pick from than what else is available. Or do you think a 2500 hour regional pilot with said "heavy" experience is a better choice? The dynamic has changed dramatically over the last 10 years.
