DLNW has matched the $30+ for MDW to DTW and MSP ($81 all-in), but sadly it appears to be nonstop only. They have not matched on the other $30 cities from MDW, which is a shame because $91 for 4 segments would have been a no-brainer.

At $40/segment, it's not quite low enough for me to pull the trigger on a day's worth of segment running between MDW-MSP.
