As a newhire you do not want to deal with DFW-ATL imho. I have heard NYC is easier, but pretty sure it's all rjs(no booking of the js, and no FA jumpseat). MSP and DTW became tough also with the merger making them mostly rj from all mainline. I think MSP and DTW might have 1 mainline per day. Hopefully as more 717s come on line, MSP and DTW will be upgauged.
