The 25m turnarounds were easy when WN was only flying to secondary airports. Not really feasible when you have more than a few flights into SFO, DEN, ATL, LGA and other places known for delays. Not to mention that there is usually an issue somewhere in the system and I think this is worse for WN as its planes route randomly through impacted airports.

Wondering if the historical stats have improved for UA, DL and AA relative to the others. The majors have removed so much capacity from the system it makes it easier to achieve the schedule when your hubs don't get stacked up. But maybe not given the number of de-hubbed airports. Maybe CLE, PIT, MEM, RDU, STL are better but ATL, SFO, ORD, DFW and LAX are still as crowded as always.
