At the risk of drawing the ire of the orange kool-aid club (i prefer Blue myself

), what makes you think SWA will be the place to be in the realistic minimum 7-10 years it will take you to get there? SWA is a fine company to work for, but it wasn't that long ago SWA was considered second tier by most qualified pilots looking for work. DAL, US Air, UAL, CAL and NWA were considered better places to be. How long ago was this? Just prior to 9/11. A good business plan, low wages (by 2001 standards) and luck kept SWA intact. They didn't improve. Everybody else dropped down to below their pay. We can argue all day as to why that happened, but SWA just steadily remained on course while the rest of the industry imploded.
In fact, during the summer of '01 SWAPA was banging the drum for wage parity with UAL and DAL. The 'S' word was being bandied about. All of a sudden 9/11 happens and SWAPA rolls over like a new bride and accepts a 5 or 6 year extension on their old contract. Frankly, that was a good call, especially considering how the industry has been rocked. But SWA and SWAPA were a few months away from a similar situation as the legacy carriers.
My point is that this industry is so fluid and unpredictable as to make any definitive plans beyond a couple of years a waste of effort. I encourage you to go 'balls to the wall' but understand that things change RAPIDLY and in general terms SWA is a fine goal, but realistically just putting yourself in position to be hired by any major airline is probably a smarter move. When you have 5000+ TT and 2000 TPIC if SWA still looks good, go for it. Just keep your options open and have a broader target the farther out you look.
Good luck.
