I just received a letter yesterday in the mail informing me that, effective July 1st, 2015, my American Express Business Platinum card will no longer receive 20% of Membership Rewards points back when booking a trip with American Express Travel using Pay with Points.
This benefit was already removed from the personal platinum card.
If you’re looking to get the AMEX Business Platinum card, there are some good offers going on for 100K and 150K MR points. The card has a $450 annual fee which can be offset with $200 airline credit per year (you can get $400 back while paying just one annual fee). The card is surely not worth it to keep for more than a year.
