OK I do agree it is kinda nuts to fly to Hawaii and only stay for one refreshing tropical drink and then fly home but you can stay for a day or so and get close to the same deal. Dates, as you can see, are VERY open. You may want to look at a 30,000 point FlexPerks redemption on this one if you live in BOS area and maybe play with fare class to get as close to $600 without going over! Here are the cheapest numbers I could find:
10,764 MQMs at 4.9 CPM
Bookable on Delta.com
DM yields a VERY sweet 24,220 Skymiles per CWSI.net!
This is one more of the mega Skymiles back under the current program that, depending on what you value a Skymiles, can make this a very cheap run!
