American Express has released a new authorized user offer for the American Express Platinum card and unfortunately there is a negative change. The terms now state:
You will not be eligible to receive this bonus for Companion Platinum Card Members that you may add to your account
There are two types of authorized users that can be added:
Additional Platinum card ($195 annual fee)
Companion Platinum Card (no annual fee)
So this means you now have to add the card with an annual fee to get this bonus. It’s unclear if this will be the case on all authorized user bonuses on the Platinum card or not, but it’s worth checking for this language if you have an authorized user offer.
