Thanks Empress.
Will I actually know by Feb 1? In that case I might take a chance and do my January flight on CP. But I can't afford to invest too many flights on CP (late January, early February) if I'm only Gold next year -- getting 2001 Elite on AC would be more important!
The 100% bonus sounds like a good test normally, but I actually expect my Platinum status will be granted by a human review in January or even February.
