If you haven't made the move to PHX yet would moving to DTW be possible? That's where you'd hold a line sooner. Just even getting transferred to LAX or DEN will take a little bit. And you'd be back on reserve. Commuting to reserve sucks and leaves little chance to work extra. Living in DTW would probably be where you could make the most money the first 3-4 years...
Your first upgrade opportunity will also probably be DTW. Living in base while all of this happen will make life incredibly better.
The DEN CRJ base is probably 3x larger than LAX.
