Some of those "snot-nosed FOs" are pushing 50+ years, but that really doesn't matter.
What does matter is not what you or I or the Unions think, but what the airlines and their handmaiden, the FAA, decide is the cheapest way to go.

I can perfectly understand the "pull the ladder up, I've got mine" attitude and I am neutral on the issue. But then again, I could walk away right now and live happily ever after from a money standpoint. Some guys are really wanting this to change and there are good arguments on both sides, but ultimately it boils down to money and the supply of available pilots to those actually making the decision.
