WN has zero hubs in the classic sense of "hub". They make a lot of money flying people in airplanes, though. So does B6 out of BOS service. SEA is not exactly well positioned to be a hub for DL, but they have O/D. MSP isn't ideally geographically positioned, either. DL didn't ditch it post merger.
It's not 2001, AA's financial structure isn't a disaster any more. And it's not time to turn planes into beer cans again. PHX is fine.
