We usually take about 3 weekend trips per year to the Cosmo. We accumulate about 10,000 points per trip. My wife and I each have our own, unlinked Identity cards. Our current plan is to use her card for everything for two of the three trips.....that should keep her at Gold level each year......and then use my card for the third trip which should keep me at Sterling. My question is: is this the best strategy for us? Is there an advantage to linking the cards or just using one card to see if the Cosmo might throw some better offers at us?
