The word is the 220 will NEVER base in ATL unless it's the last stand. The heavy metal covers all of FL so we don't want to take seats away from that. The Canabus is more efficient on the "long skinny" routes between business destinations and 2+ hr lengths. The 717, for now, covers anything shorter, but the 220 is being pressed into replacement service faster due to the 717 monthly inspections and longer stage lengths out of there. The 220, right now, only does IAD, SBA, and BUR from ATL. The schefule for MSP in December is larger than other bases, hence the opening. There are a lot of commuters in MSP that have been patiently waiting for the opening and I hope every one gets in though it'll be sad not to fly with them, again. I just hope this opens holes on other fleets for some back fills.
