True. People look at it saying its currently a 16 year flow, when really it is currently a 12 year flow, because 3 of those years there was zero hiring, and one year only 8 are left. Yes the people currently flowing have been here for 16 years. That will not be true for everyone else. As far as projected upgrades or flows go, here is an idea of who is left still on the seniority list and how it will both effect upgrade time and flow projections. I took what was on the ALPA unofficial seniority list from DEC that I got from a Eaglet, so it is not 100% correct or current.

The 99s are just about gone to the flow. Anyone more senior is staying, and also a few including in this list who are choosing not to flow.
