Southwest does not really operate point-to-point anymore. It is basically a hub and spoke network, albeit with LOTS of hubs, some small and some large.
Very few markets can support point-to-point service (e.g., DAL-HOU, HOU-SAT, SAT-DAL, BWI-LAX, etc.) All the other markets (e.g., TUS-MCI) require a stop along the way. Adding small planes will work fine with Southwest's system.
I dunno about that JS. From MCI, I can go to 22 Southwest cities on a nonstop flight. You're right, TUS isn't one of them. Compare that to 2 cities on United, 2 cities on AA, 2 cities on NWA, 3 cities on U, and 4 cities on Delta. And I doubt seriously that 22 fewer seats than a 737-500 is going to allow them to start serving TUS-MCI with a nonstop flight anytime soon.
And I agree with Busdriver on a couple of points - first that I doubt seriously that SWA would accept any kind of "regional jet" outside of a 737-600 configured for 100 seats. I don't see them as "following JetBlue's lead" in that I'm not so sure that JetBlue's lead is the right one. First off, Jetblue admits that their new "regional" jet will increase their operating costs by 14% right off the bat. Eventually, the one big happy family feeling will grow stale, especially among pilot ranks since IMHO, pay rates are going to cause a problem. Then you have the transition costs as the "RJ" pilots move over to the 320's. Considering that Jetblue, though profitable, is running with a breakeven load factor of nearly 80% - you start bumping up costs and you're going to have to either bump up the breakeven load factor, or bump up the ticket prices. Neither are an enviable position to be in, IMHO.
And I agree with Busdriver on his statement:
Can't argue with that. One of the things that has made SWA a darling of Wall Street is their consistency in sticking with their business model. Should they begin to emulate the other airlines that are losing money by introducing a new aircraft into the fleet, I think Wall Street will send them a reminder of their displeasure.
