The quickest and best thing you can do to improve your QOL at SWA is to GET A LINE. Any line. This especially applies to commuters.
Reserves lose out on QOL and pay improving tools like ELITT, TTGA (for the most part it's impossible to trade or give away reserve), vacation pull, overlap pull, pay protection for next day reroutes, etc etc etc.
The worst line is better than the best reserve. There are very few people who prefer reserves in "slow" months, but with utilization well above 80 percent, those don't really exist any more.
