When clickmiles offers a double redemption promo (it was mentioned in the WWF flyer talk buzz that this happens at least yearly)is there a limit to the number of points doubled like Starwood's 10000 point limit? If so can anyone tell me what this limit has been in the past? I'm trying to decide how much to donate to the WWF based on the possibility that the miles gained could be doubled at a later date. This is my first post. Thanks for responding.
