My Guess is yes, however I have seen DING fares for 34 one way STL-PHX, and PHX is one of the top markets for SWA at STL with 6 daily. So It might be just random cities at random prices.

There was lonly two or three days where they were offering that fare. So my guess is that the ding fares are for days/routes that arem't filling up. So they lower the fares to create more demand on routes that seats would otherwise go out empty but who knows.
