I just called Delta’s DOT-COM support in Dallas Texas and got a supervisor to both confirm and note my account that I am eligible for the LGA 2x promo. If it is NOT showing up in your “My Promotions” page you may want to do the same. Also keep in mind, per the convoluted rules, the 1st flight you don’t get 2x MQMs but the 2000/2000 bonus. So, if you do what I showing above, here is what you get:
Flight 1 – 3264+2000=5264MQMs
Flights 2-7 – 6528MQMs
Total for 7 days of flying back and forth = 44,432MQMs
Total cost $1,666 at 3.75CPM. Not all bad plus a boatload of Skymiles on top of that to offset much of that cost. Keep in mind the medallion bonus is not doubled just the base miles. Still a bunch of Skymiles for the 7 days of flying. Also does work either way.
You can do connections but only get 2x for the LGA to wherever segment btw both per the terms and DOT-COM support.
I picked DEN as the start / finish as the AUA route is not really feasible and the BZN seems seasonal to me anyway from the Delta route map from LGA. What do you all think? – Rene
