OK, I just read great news from @gleff.
While anyone applying for the cards starting today will see the new annual fee right away...- Existing Business Platinum cardmembers will not see the higher annual fee until their next renewal date or after December 2, 2025.
- Existing Consumer Platinum cardmembers will not see a higher annual fee until their next renewal date on or after January 2, 2026.
If your card renews in November 2025, you won't see the $895 annual fee until November 2026. But you get all the new benefits right away.
My AMEX Plat renews Nov 22. This means I won't get hit with the increased annual fee til 2026. And I will benefit from a number of the new and improved benefits.
