With the state of the industry, just get to the first company that will get you flying without killing you in the process. You don't have to get married to TSA, just date and fool around until something better comes along. Don't spend the bonus money that you have to pay back if you leave early.
TSA is probably not a place that you want to go to build up your 401k plan, but they will get you 1,000 hours of 121 time in a RJ faster than just about anyone out there. Just don't expect a quick upgrade. After that, you have plenty of options to consider.
FWIW, Compass is probably not the best place to wait for a call. They could possibly be losing both their Delta and American flying. Sure, I'd fly for them today, but I wouldn't pass up a similar paying job waiting on them.
