@mmmears -- I've mostly away from my computer all day, checking in here and there, but really find myself about 4 pages behind and catching up. I think you might've caught
@SouthFayetteFan's post here:
https://www.disboards.com/threads/i-love-credit-cards-so-much.3528202/page-2715#post-59817758. My understanding was this was previously only possible on Amex co-branded cards within the same family of cards.
If you or your husband already have an Amex-branded card, even if it's not the new Amex Gold/Rose Gold Card, you can generate a referral from that Amex card (i.e., your or your husband's Platinums) for the Amex Gold/Rose Gold Card or any of Amex's other cards, and the referral bonus would go to your or your husband's MR account accordingly. Because MRs cannot be combined between different members, you should consider where you want the respective bonus points to go when referring and applying.
We always encourage the people in this thread and on DISchurners to seek the best offer and if you have the ability to self-refer yourself or refer a partner to the new Amex Gold/Rose Gold Card or any of Amex's other cards,
please do so. This would net yourself the referral bonus and the welcome bonus (or the referral bonus to one player, and the welcome bonus to the other).
