The price on this is nice and you can do it all in one day. The fact it is a red-eye is a negative. Another plus is you get to go check out the brand new Delta Sky Club in DEN!
Personally, cuz I hate red-eyes, I would consider this one in 1st class vs coach. You only get one meal that is the last leg but you can eat at the MSP Sky Club or the MSP Escape lounge (a better choice).
Here are the cheapest number in coach:
4,184 MQMs at 4.3CPM
Bookable on Delta.com via Kayak.com
I have included the Google Flights or Kayak links and for those of you new to this, 1st log in to your Delta.com SkyMiles account and THEN you click the above links and it will, after you choose flights, send them over to Delta.com. Very simple! – René
