From Sept 1- Dec 31, Hilton guests who want to earn Delta elite status, have a pretty good deal. You can choose 2 options:
1) Delta Mileage (Variable Miles Members): Earn 1 bonus mile + 1 Medallion Qualification Mile (MQM) for every U. S. dollar spent on a qualifying stay, up to a maximum of 10,000 MQMs.
2) Bonus Delta Mileage (Fixed Miles Members): Earn 500 bonus miles + 500 MQMs per stay. (maximum of 10,000 MQMs.)
For me, this is attractive- because I don’t have as much flying this fall, but a lot of hotel stays. I can’t bear the thought of dropping a Medallion level, so I may bank some of my hotels to Hilton to pad my Delta account.
To get the MQMs, make sure you have Delta selected as your Double Dip airline partner.
