Both
Delta and Sun Country have direct flights from msp. Sun Country starts service in late December and runs thru April I think. Not sure about Delta schedule. Both Fly on Saturdays. Both had attractive fairs in Jan but it varies week by week. Went up on both after Jan. We just got a good deal on Sun Country for Jan 21 2017, 590. I've never booked this early before. I really like direct flights in the winter.
