The A220 is being used to replace most of the 717 flying at MSP beginning in May. (320s and RJs picking up the rest) Delta’s published flight schedule shows the 220 taking bunch of short haul out of MSP from the 717 too, legs like ORD, MCI, STL, and MKE.
Don’t see any 717 routes being replaced by 737s yet.
