With another HT to FT for this find on this nice one day run at an amazing CPM on a weekday. The better one may be the weekend 1st class run at just about 7 CPM (I like under 8 CPM in 1st btw).
The other reason I like the 1st class find is if you have FlexPerks points you can spend 20k since the 1st run is just under $400. Do note you can do it this some dates from Boston but you have to overnight.
Here are the coach numbers:
3,638 MQMs at 3.2CPM via MSP 2x
Bookable direct on Delta.com via Multi tool
