I agree it's all still a bit murky (as an outsider) but a hopeful sign I think is the talk of more point-to-point flying. An analysis I worked on last year showed that the US is way over-hubbed -- airlines were sucking travelers through hubs to keep the hubs viable, when there are still plenty of markets (JB and SW are correct) that have enough demand to support direct service 2-3 times per day. Do you really think SFO-DEN has so many wide-bodies because of the OD demand? No!
In this world of comoditization adn price matching, the great thing about direct service is it's one of the few things that still commands a price premium. Many people are prepared to pay quite a bit more to travel direct and save time rather than connect through a hub. And US does have some great focus cities and spokes (BOS and DCA are obvious). As you expand the network this way you also get cost benefits (the "scale" at the spokes improves, you can get a lot more flights without, usually, needing more gates etc etc). As more traffic bypasses the hubs you have to re-gauge the flights to the hubs, and all this has a fleet mix impact, but nothing insurmountable.
I'll wait until I see more of the plan, but at least the talk of increased pt-to-pt, if done directly, makes very good sense.
