Above SS is of Dad's Amex Account, not mine. I need help here. On Platinum, I have 1.70 lakhs MR points. If I add the newly received MRCC to Platinum instead of Gold (initially that's what I thought), can I redeem 18k and 24k...? Both have different usernames to log in, but I don't lose Platinum benefits of transferring to Marriott (I haven't transferred yet because I don't have a travel plan yet, and I'm still learning the dos and don'ts of transfer, so I can't mess up here). And the 4 lakhs milestone benefit and all would be received just like before on Platinum; only 18k and 24k will be unlocked. I haven't tried to initiate the process, though. I'm aware I can remove and add the credit card back, but I thought let's ask here, right?
