DTW-BOS was $200 last month. The correlation seems far, far too great for it to be anything other than deliberate. I frequently see the upsell offers lag changes in fare differential which seems to indicate a human has to try to update them and frequently forgets.
Also, wow, sub-$100 is some serious discounting for BOS.
