Wyndham has announced a change to status earned through credit cards:
Beginning February 1, 2025, Wyndham Rewards cardholders will no longer be able to match their Wyndham Rewards PLATINUM and DIAMOND Member Level obtained as a result of being a cardholder (as opposed to earning their member level through stays) into the Caesars Rewards program.
Currently the Business earner card grants Diamond status (personal card grants Gold status) and Earner+ grants platinum status. Having the business card was useful for people matching between the two programs to get a free cruise. In addition the amount of points you can transfer between the two programs has been halved to 30,000 points (from 60,000 points).
