Call this a selfish weekend lounge run at a high end of acceptable CPM but it is on a weekend, you get 24hrs in DFW to go to the Centurion Lounge and enjoy! At least something for MSP hub captives to think about. Here are the numbers:
3,274MQMs at under 7.3CPM
Bookable on Delta.com
DM yields 7,368 Skymiles per CWSI.net!
Personally I would do this if I had say a $50+ voucher to burn and some hotel points (& access to the Centurion lounge too). That would bring it down to a fun weekend getaway. Oh, you could spend some time in Dallas too I guess 😉
