If you add a free additional user to your Delta Gold consumer account via the link above and spend $500 on the new additional card within 3 months you will get 2,500 bonus Delta miles. There is a limit of 1 bonus per primary Delta account.
The terms state that the bonus points can take 8-12 weeks to post, though typically they post much quicker than that.
Additional AMEX cards qualify for AMEX Offers. You can have up to 99 additional users on a primary card account, but the bonus is only for adding 1 card.
Additional Card Members must be at least 15 years of age. You are able to add yourself, a family member, or a friend as an additional user.
A social security number is required for this offer. There is no hard credit pull for adding an additional user.
However the account will show up on their credit report, which means that spending on the card can help or hurt their credit score depending on your credit utilization and payments.
An additional user card will also count against the user with Chase, which limits approvals for many of their cards if you have had more than 5 new accounts in the past 24 months. It is possible to appeal that decision based on it being an authorized user account if you say that you don’t use it and aren’t responsible for payment on the card, but some have been turned down because of that approval guideline. It is possible to have the additional user account removed from the credit report by closing it and requesting removal from the bank and/or all 3 credit bureaus.
