ORD it’s pretty senior. DTW is way faster for holding a line. Also MCO could be a good option out of BNA. No matter where you go, it would take at least 6 months to hold a line at a jr base (12-18 months at ORD/DFW). So the first question you need to answer yourself is where do you want to sit reserve? As a commuter I would go to base that has R19 (MCO does). R19 has only 15 periods per month, so that will give you plenty of time at home. The downside is that they’ll use you less, so better have a decent crash pad (and maybe nice WX .

Once you’re a lineholder you can swap/pick up trips from any base, making BNA a strategically positioned airport.
Obviously, there’s nothing like living in base, but at least you’d have a way better commute that our friend from Lubbock. (waaayyyy better)
