My search-fu is broken this morning... I have an AMEX Platinum and was considering adding my wife as an authorized user for the year so that she can get Global Entry reimbursed and can get access to lounges without me--she might end up doing a decent amount of work travel this year. If I do that, will she still be treated as a new cardholder for the purposes of future sign-up bonuses? I assume she will, but best to ask, considering a sign-up bonus of 50k points or more is definitely more valuable than $100 GE app. Thanks in advance!
