Southwest trip for pay explained by someone who does it

Five years Las Vegas. Southwest pays per trip (a unit tied to flight time and sectors) rather than per block hour like the legacy carriers. Practical effect: efficient days with more sectors pay well, long days with delays pay less well than at the hourly carriers. The recent contract raised the rates a lot. Reserve exists but the rhythm is domestic, quick, and home more nights. Fun culture is real, though every airline says that.
