Republic Airlines: For me it would be nice to be SDF based, as its about 15 minutes from our house
This pretty much answers your whole question. They have a lot of experience helping pilots like you make the transition to the 121 world, and if SDF is obtainable it is clearly where you want to be for whatever period you are on reserve. That beats hell out of either a one and a half or a a three hour car ride, or the uncertainties of a jumpseat commute.
