Finaly some hard facts!! Thanks emb145!! Below is so correct. And things wont change very quick with a slight shrinkage...

"The current upgrade is held by a 2007 hire making current upgrade time just over 8 years. I do agree that this will come down, maybe to 6 or so years but that may take a couple of years from now to reach.

The latest person to flow is a mid 1999 hire. So, currently a 15+ year flow. I agree that this number will come down as well, but it will take longer. Five years from now, you might see a 10 year flow or a bit less. One wild card is the ability to get new hire pilots in the door. Envoy has averaged hiring 125 per year over the past 3 years. "
