Hilton just unveiled their second quarter 2012 promotion of Double Hilton HHonors Points or miles. This promotion starts on April 1st and ends on June 30th, 2012. This promotion is rather straightforward. You will receive either double points or double miles. You need to register to this promotion before your stay.
If you want to earn miles, you need to choose between fixed or variable miles. Fixed miles are number of miles per stay (or nights in case of BMI) where variable miles are dependent how much you spend. In my case the fixed miles is always a better option. For longer stays the variable miles options is probably better.
Note that once you have chosen either double points or miles you cannot change the selection. Double points is better if you have longer and more expensive stays.
The list of non-participating properties is getting longer. Double check that the hotels you are intending to stay during the second quarter have not opted out from this. There are only six non-participating properties outside of the United States.
Here’s a list of participating airlines and their fixed mile options for Hilton stays. My favorite still is BMI that earns 1000 BMI miles per night regardless of the Hilton brand, and for up to 3 nights. Three night stay would thus earn 6000 BMI miles. Word of warning. Lufthansa is in a process of selling BMI to IAH, the parent of British Airways and Iberia.
