I'm also a SWA guy. How easy is it for reserves to break guarantee and by what margin? As flyguy81 mentioned, at SWA, you'll make more than guarantee the instant you're called out, and if you get rerouted while on the road or otherwise messed with, you'll make substantially more than guarantee. In other words, if you're starting a month with 90 TFP, it's not uncommon to finish the month with around 120 TFP and seen it as high as 145 TFP without picking up anything on your days off.
