I did a ATL-DFW via SLC and a ATL-IAH via SLC in 2016, so I was looking for the same deals in 2017. Lo and behold, the fares are still low, BUT the fare rules now specify direct/nonstop which obviously pushes the CPM into "stoopid" category. Shame! I've seen this on a few more of the "good" 2016 runs so I'm in the middle of looking for new sweet spots for 2017....
