True, but how many people can consistently achieve two-leg day trips month after month for a significant part of their careers? While I'm not familiar with Delta's system, at AA, securing those day turns typically requires being in the top 10-15% at each base, which generally correlates with wide-body captain seniority. Everyone else on the narrowbody side is stuck with 3 or 4-day trips with multiple legs per day to satisfy the "optimizer" that came about because of the Average Calendar Day LOA.
