The whole system is designed to reinforce their filthy addiction to cheap regional labor. They will hire as many military pilots as possible in the time of pilot shortage, because this forces civilian pilots to flow through their regional feed in order to make it to the mainline. That's the whole point of them offering increased flow-through programs to their regional airlines in exchange for decade-long contracts that maintain indentured-servitude wages with 1% yearly raises. If there was no pilot shortage, they wouldn't be hiring military pilots either, except at the regional airlines. They will be cold and dead before they give up on this dream for themselves and their shareholders.

The whole debate about whether they prefer a healthy mix of experience, etc. is irrelevant.
