I think you're in the wrong airline for your geo-needs. If you're that anchored to FL, I'd keep apps updated at SW and AA if I was in your situation.

I hear Houston->Miami is not a tough commute for the AA guys, so perhaps central Florida to Houston would be a sustainable option once you can hold IAH at UA. What's your current commute situation? I hope for your sake you're not currently double commuting to airline and reserve job. I don't count driving when I say commuting btw. Good luck.
