I'd rather be an International wide body FO for the rest of my career at Delta with 17-18 days off every month than be a 737 CA flying 4 legs a day to the same places all the time at SWA. Anyone who thinks narrow body flying 4-5 legs a day is an easy job is kidding themselves. Just an opinion but I have done both and for me it would be Delta hands down due to the variety of flying. The same can be said for American or United. If I was in my early 30's, I'd get the hell out of SWA ASAP unless I was living in base and drove to work. Even then, it would be a hard pill to swallow because of the fact that I'd be flying a 737 forever. Not my cup of tea and just an opinion.

Also, SWA, as successful as it may be and there are no doubts about that, is still a low cost carrier. American, Delta and United are global airlines. Something to think about.
