I mean SWA pilots always tout how much they get paid and how many days off they get per month so to me it sounds like they have the best NB flying on the planet. So in your situation the ONLY reason you would ever leave right now from your position is because you want to do WB flying. No other reason for leaving makes sense unless you are concerned about SWA's long term viability. Whatever you do you will know you made the right decision in 35 years.
