If you replace 35 Crj200s at PSA for say 35 CRJ700s it'd cost ZERO training dollars...... New hires I see as a push.
Upgrade at PSA is a week of ground, maybe 6 sims total then IOE. You can get an FO to CA under a month easily.
Who knows what's happening. We all will find out shortly. USairways mgt team seems to be ok with wholly owns. They've kept them around for a reason. They have direct control and if things go south can reduce block hours etc as they desire with no contractual obligations of a FFD contract. With USairways mgt keeping the power I'm unsure if their mindset will change after a merger.
