This is interesting. Yes, WARNING, it is EVIL BASIC E fare so you can not upgrade. But, you can spend much more and fly all 1st class as well. After the choice, you have a few options to think about.
The first is, since this is a weekday run, go after work and fly out, then just take one day off. Or, take two days off and enjoy quality Centurion DFW lounge time. Then off to HardEight BBQ. Maybe you can get some work done in the club? 😉
Any, here are the EVIL BASIC COACH numbers:
5,141 MQMs at 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
