Do you have any interest in Southwest?

Going to Sun Country, knocking out a B-737 type, and then getting time in type might set you up for success. Also, they're due for a new contract and they'll likely catch up with the other U/LCCs ... maybe.

Living in base is awesome, being 3 hours out though is just far enough away that you're doing the right thing by looking at other carriers.

Have you tried for Spirit or Frontier? Spirit has DFW and a pretty nice contract.
