My family traveled on the Allure this past week. As we were in the terminal waiting to board I noticed my wife's C&A profile had upgraded from Gold to Platinum. We have the same number of points, and I showed as Gold (as expected - we have about 15 points prior to sailing). When we got into our stateroom, she had welcome letters advising her of discounts for Platinum status, whereas I had one for Gold.
I cannot for the life of my figure out why this happened and am curious if anyone knows why.
