OK you SLC hub captives here is one for you. The cheapest is staying two nights in NYC (yeah I know how dumb that sounds, cheap=NYC, not so much)! But, if you want a Sunday in NYC and need MQMs this could work two weekends in NOV. Or, if you don’t want to overnight, at under 6CPM you can in DEC do this run all in one day for the same MQMs! Here are the numbers:
4,700 MQMs at 4.2 CPM
Bookable on Delta.com
DM yields a nice 10,754 Skymiles per CWSI.net!
