Its back with a HT to reader Scott. There are, slightly playing with prices, a number of ways to play with this one. You can do it all in 1st class in one long day or in coach (just avoid E BASIC fare class flights). If you are a GM+ I sure would think about coach as weekend UG chances are much better. Then again, for the price, the 1st class MQMs is much better. Just consider both. Also consider staying over a day if you like visits to the Centurion Lounge DFW and HardEightBBQ near Dallas airport (just a short UBER or LYFT away folks)
Maxtrix is not showing all the dates at this lowest price so play with the dates you want and see if it pops up.
Anyway here are the 1st class numbers:
5,938 MQMs at 6.5CPM
Bookable direct on Delta.com
or example on Kayak.com in 1st class
or example on Kayak.com in coach (no E class)
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
