I travel enough that lounge access would make the Platinum card worthwhile for me. My wife just received (for the 3rd time, so maybe this is a normal offer, but it seems pretty good to me) a 100,000 point sign up offer for that card. I also frequently get offers, but the sign up bonus is significantly lower when I get the offers. My understanding is that only the primary card holder gets lounge access (I understand the guest policy). My question is: Is there a way to sign up with that bonus, but make me the primary card holder, as I usually travel solo for business, and my wife would therefore be unable to guest me in, as she would not be with me? Thank you for your input.
