If you want to be DFW based I'd say its probably a good place to go. They're going to shrink, that's not surprise at this point, a retention plan is in the works, and once the 175s come on property hiring classes will start filling up more. Pick a regional based where you want to live at this point. No point in chasing a quick upgrade when you'll likely be able to move on to bigger and better things 5 or so years down the road.
Also, there's no harm in doing the pipeline thing now, enjoying the travel benefits, and not spending any of the bonus. If a retention plan does actually materialize, it's going to have to be offered in the next few months, so you should have some time to think.
