I left NJA for SWA around six years ago. Despite the contract and management issues we're dealing with right now, there's not one single minute that I have regretted jumping ship and starting over. I was physically exhausted after every tour, and would need a day of recovery once I got home before I was useful for much.

At SWA, the pay is better, I'm not at work nearly as many days, and I'm not gone for a week at a time. My hardest days at SWA are still easier than an average day at NJA, without question. I'd highly recommend looking at the other majors as well.
