I used a combination of ITA Matrix and Google flights to find it. Once I discovered the 2 different fare basis with good cpm on both I just played around and forced routing through ATL multiple times to get the lowest cpm possible for this routing. I had a difficult time trying to book it, but ended up getting it done by booking 2 individual multi city segments on DL.com So I booked COS-ATL-MCI-ATL-PHX as one multi segment itinerary for ~$158 and PHX-ATL-MCI-ATL-COS as a second multi segment itinerary for $~164.
