Hilton offers a double double dip promo
Hilton has a new promotion out for Q4 2012 targeting guest in the Latin America and Caribbean regions, as well as some US properties. Guest who choose to “double dip” with both HH points and airline miles in Aeromexico, American Airlines, Avianca/TACA, Multiplus or United (includes Copa) can earn double airline miles, either from variable or fixed rate earnings. The list of participating hotels is somewhat meager but if you normally credit to one of those airlines anyways then no reason to skip the registration. It might come in handy.
