What happened
Select American Express Platinum Card members who receive a targeted email can register for Hilton Honors Diamond for 90 days, then keep it through March 31, 2028 by completing 10 nights booked directly with Hilton during the trial.
Registration closes September 7, 2026. The 10 nights have to be booked directly with Hilton. That bar replaces the usual 50 nights required for Diamond. Cardholders who did not receive the email cannot register.
Check the Amex inbox and register by September 7, 2026 only if 10 Hilton nights booked directly during the trial are realistic.
