Hilton is offering 100 free Hilton HHonors points when you enroll in their Thank Again program. Thanks Again enables you to maximize the points you accumulate from your existing travel loyalty programs when you shop, park and dine at thousands of retailers in and around more than 100 airports.
Obviously this is not worthwhile for most people, since the value of the points is generously at around 50 cents. But these deals are useful for keeping inactive loyalty points from expiring. They will extend the life of your points another 12 months.
Must enroll before December 31st, 2016.
