All we can do is speculate on what will happen, taking into account the industry history. Things are always changing, you just need to make the best decision for you, using the available information and literally hope for the best.
Certainly the industry is changing right now. Almost a complete turn around from this time last year (almost). A lot of Regionals have slowed up big time, some of them even having trouble and few have gone belly up. I would expect the next few years to be slow, with little movement upward. I don't want to see that, because no movement means long upgrades for everyone.
I'm just happy to be in the position I am in right now. I think leaving Colgan was a smart decision on many levels. If I'm going to get stuck at a Regional, I'd rather be stuck at one with good QOL and a Union. Plus I think we're one of the few Regionals still actively hiring on a large scale. I expect that too will slow down, but hopefully not before I get quite a few peope behind me.
