IHG is now allowing Diamond elites and business members to to transfer points between accounts for free. Normally there is a $5 charge per 1,000 points.
eginning December 6, 2023, Diamond Elite and IHG Business Rewards members may transfer points free of charge. For all other Members, the Member authorizing the transfer will be charged $5 US per 1,000 Points transferred, payable via valid, accepted credit card or approved payment method.
The business enrollment link can be found here. You need to have been a business member for 30 days before point transfers will be available. There is no fee to become a business member currently so this is a great way of moving orphan points around without a fee.
