Would this then count as activity: I have some miles that I want to use December of 2012 (I know I am nuts for planning what to do with miles that far out) - I know you can't book that yet, but once that is bookable does the actual booking count as activity? I will be able to book within the 18 months of no activity window, but the actual redemption will likely be just over that window. Is there a chance that points that are being utilized for an active reservation can disappear (and thus the reservation presumably cancelled) since the actual date I will check-in to the hotel and use them will be more than 18 months from when they are earned (assuming no additional activity between now and then).
Hope that isn't too confusing, just wondering what I need to plan for. Thanks!
