My fiance' has a Bonvoy Elite account and they will not allow him to put me on as an authorized person to discuss the account i.e.make reservations, transfer points for flights, etc...

I'm the one that handles all of our travel arrangements, and knows the program. I think it is absurd that he cannot add an individual (at least one) to the account to handle things for him. What if heaven forbid something happens where he can't physically make the arrangements himself or speak to someone about the account does that mean he can't use his account any longer?

Has anyone dealt with this situation, and if so we're you able to add an authorized person to make transactions/reservations on the account?
