There are so many ways to tweak this one and a HT to reader Brian for the help. You can route to SAN btw but I like the PDX one due to the fact that you can go out and back in just one day with no red-eye. That is worth a ton. But, the 1st class red-eye is also really nice at under 7CPM so do think about that one too! Here are the numbers
Cost $200 or $587
5,062 MQMs at 4CPM in coach
8,596 MQMs at 6.8CPM in 1st
Bookable on Delta.com
DM yields a nice 11,390 in coach and 15,758 in 1st Skymiles per CWSI.net!
