What are your goals? I assume getting out of the regionals. If thats the case and you are literally months away from upgrade, I'd say stick it out, get your time and use that time on reserve to try and nail that job at the Big Show. The PIC will do nothing but make you more marketable. So I think you need to ask yourself, which is the harder pill to swallow: a few more months and then an upgrade at Mesa, sucking it up at company thats miserable in a city you don't like all in the name of the almighty TPIC or 2 more years as an FO, another training cycle and year of probation, first year pay and having to commute?
