They've awarded a bunch of CA's Boise the past several months. FO staffing is currently way behind, with only two FOs that have that as their number one choice to transfer in. If starting class soon it looks like getting based there should happen rather quick. As far as holding a line, that's rather hard to tell. First off, the number of lines at every domicile changes every month based on how busy we are. Certain times of the year are busier than others. Second, future staffing, due to transfers, upgrades, resignations, etc. are a total guess. The junior line holder in Boise for March may have just finished IOE. Someone getting based there later this summer could sit reserve for a year, or not at all.

CAS? I'm not sure what that is. If you are referring to at risk flying, I don't believe the ERJ does any of that. Strickly CRJ 200, I think. Someone can correct me if I'm wrong.

I believe BOI and SEA are growing with the new Alaska aircraft that are arriving this year.
