But your series of questions implies that you assume Delta wins those metrics, which may not be true. (I haven't investigated them, and I bet it varies significantly by city pair, and SWA is generally known for successfully quick turnarounds.)
DL does score at or near the top on those metrics. WN has fared very poorly on those metrics over the past few years. Not saying those things do or should matter to most consumers, but there is a significant disconnect between your view of WN and the reality of their operations - they are not the well-oiled machine you imply they are.
