About 9 months back I referred both my parents for a amex gold charge card so I could get the referral points. I have since cancelled and reapplied for my plat for the joining bonus while they have held onto their golds. I want to refer them again before I cancel my second plat. If they cancel their cards would I be able to refer them again after a few days and receive the referral bonus again?
I'm fairly certain you'd be OK with your referral bonus, but your parents would not get any introductory bonus unless they went 6 months without a Membership Rewards account.
