Attrition is a factor I forgot to mention, thanks for pointing that out. I would say it would be very little as most guys inside 300-350 global are lifers and won't retire for about 7-10 more years. Beyond 350 global, it just depends on how fast guys get 1000 pic and who they know to get hired elsewhere, and how picky they are. Right now attrition is very little in the Captain ranks...
