From what I understand, Endeavor is fully meeting their hiring goals right now and adding two planes a month. I bet their SSP will turn into a flow at some point in the near future. Upgrade is about to drop to two years or less.

One wholly owned for each legacy doing all the regional flying is the likely future. Crew bases in everyone Legacy hub and 100% of legacy hiring from the wholly owned flow agreement. 60K for FOs, 100K for captains and a five year flow would keep the wholly owned staffed no problem. Legacy's carriers won't be flying E175s and 900s.
