The word from the VPs in a recent upgrade class was no DFW base. Our DFW flying is primarily designed to route airplanes into the right place for overnight maintenance. We don't do anything west of DFW, and doing so would require us to go to 24 hour staffing in the SOC. Too much cost for too little benefit right now.
Bases do come and go, and the Mesa airplanes could really change the equation. But I'm saying that, not our execs.
