i have a hilton amex card i use regularly, and i've convinced my spouse (who never travels unless it's with me) to get one as well. it would be far more convenient and valuable to have all the points from the new card deposited into my account. the 15k bonus points for first use is a factor, and i'm sure we can find a way to put 4 stays on the new card.

so is it possible to have two separate hilton amex cards linked to the same hhonors account? or must each active amex account link to a distinct hilton account?
